The direct anterior approach (DAA) is gaining popularity in primary total hip arthroplasty (THA). Although DAA has demonstrated many advantages over other surgical approaches, periprosthetic femur fractures (PPFF) rates continue to be higher. Femoral stem designs that allow for easier insertion via a DAA may contribute to the higher rates of fracture seen in this approach. Certain stem designs and fixation methods may reduce the risk of PPFF via a DAA in primary THA.

Ligament balancing in revision knee arthroplasty is crucial to the success of the procedure. The medial collateral ligament and lateral ligament complex are the primary ligamentous structures that provide stability. Revisions can be performed with nonconstrained cruciate-retaining, posterior cruciate substituting, or anterior-stabilized/ultracongruent inserts when there are symmetrical flexion/extension gaps and intact collateral ligaments. When the collateral ligaments are insufficient either due to attenuation or incompetence from bone loss, a more constrained knee system is needed. Constrained condylar knees provide increased stability to both varus/valgus and rotation forces with a nonlinked construct. This increased constraint, however, does lead to increased stress at the implant-bone interface which requires more robust metaphyseal fixation. In cases of significant soft tissue disruption, severe flexion/extension gap mismatch or extensor mechanism disruption, a rotating hinge knee is needed to restore stability. Advances in revision implant design have led to improved outcomes and longer survivorship then earlier iterations of these implants. Surgeons should always strive to use the least constraint needed to achieve stability but must have a low threshold to increase constraint when ligament integrity is compromised.

Background: The purpose of this study is to evaluate survivorship and outcomes of high-activity patients compared to low-activity patients after total hip arthroplasty.
Methods: A retrospective review identified 2002 patients (2532 hip) that underwent a primary total hip arthroplasty with vitamin E-infused highly crosslinked polyethylene liner. Patients were divided into 2 groups based on their University of California Los Angeles (UCLA) activity level: low activity (LA) (UCLA ≤5) and high activity (HA) (UCLA ≥6). Outcomes included Harris Hip Score, UCLA activity score, and reoperations. A multivariate nominal regression analysis was performed to evaluate the significance of postoperative activity level on survivorship.
Results: The mean follow-up duration was 4.5 years (range, 0.3 to 9.9 years). HA group had significantly higher improvements in Harris Hip Score (HHS) (P < .001) and UCLA activity score (P < .001). Aseptic revisions were performed in 2.1% of the LA group and in 0.4% hips of the HA group (P < .001). After controlling for age, gender, preoperative pain, HHS, and body mass index, a higher postoperative activity level remained a significant factor for improved aseptic survivorship with an odds ratio of 4.9 (95% confidence interval, 1.1 to 21.2, P = .03). The all-cause 5-year survivorship was 99% for the HA group and 96% to for the LA group (P < .001). The aseptic 5-year survivorship was 99.6% for the HA group and 98% for the LA group (P < .001).
Conclusions: This study found that a higher activity level after primary THA was not deleterious to survivorship at short to midterm follow-up with modern implants.

Common peroneal nerve palsy (CPNP) after total knee arthroplasty has a reported incidence of 0.3% to 4% and can lead to foot drop, equinovarus deformity, and marked disability if not resolved. Patients typically present in the early postoperative period with weakness or inability to dorsiflex the ankle and decreased sensation of the dorsum of the foot. The authors report their experience, technique, and outcomes of acute peroneal decompression within the first 90 days postoperatively for 5 patients with this unique complication. Preoperatively, all patients had valgus deformity with intact dorsiflexion and sensation of the foot. The diagnosis of CPNP was made on postoperative day 0 or 1 in all cases. After diagnosis, patients were offered acute peroneal decompression and returned to the operating room electively. The surgical technique for dissection, release, and decompression of the nerve is described. At an average follow-up of 12 weeks (range, 6-16 weeks), all patients showed return of motor and sensory function, as tested by ankle dorsiflexion and dorsal foot sensation, with average motor strength of 4.6 of 5.3. Acute decompression of acute CPNP after total knee arthroplasty is a prudent treatment option that provides good functional results and rapid recovery. [Orthopedics. 2021;44(4):e556-e562.]
Aims: The purpose of this study is to evaluate early outcomes with the use of a smartphone-based exercise and educational care management system after total hip arthroplasty (THA) and demonstrate decreased use of in-person physiotherapy (PT).
Methods: A multicentre, prospective randomized controlled trial was conducted to evaluate a smartphone-based care platform for primary THA. Patients randomized to the control group (198) received the institution’s standard of care. Those randomized to the treatment group (167) were provided with a smartwatch and smartphone application. PT use, THA complications, readmissions, emergency department/urgent care visits, and physician office visits were evaluated. Outcome scores include the Hip disability and Osteoarthritis Outcome Score (HOOS, JR), health-related quality-of-life EuroQol five-dimension five-level score (EQ-5D-5L), single leg stance (SLS) test, and the Timed Up and Go (TUG) test.
Results: The control group was significantly younger by a mean 3.0 years (SD 9.8 for control, 10.4 for treatment group; p = 0.007), but there were no significant differences between groups in BMI, sex, or preoperative diagnosis. Postoperative PT use was significantly lower in the treatment group (34%) than in the control group (55.4%; p = 0.001). There were no statistically significant differences in complications, readmissions, or outpatient visits. The 90-day outcomes showed no significant differences in mean hip flexion between controls (101° (SD 10.8)) and treatment (100° (SD 11.3); p = 0.507) groups. The HOOS, JR scores were not significantly different between control group (73 points (SD 13.8)) and treatment group (73.6 points (SD 13); p = 0.660). Mean 30-day SLS time was 22.9 seconds (SD 19.8) in the control group and 20.7 seconds (SD 19.5) in the treatment group (p = 0.342). Mean TUG time was 11.8 seconds (SD 5.1) for the control group and 11.9 (SD 5) seconds for the treatment group (p = 0.859).
Conclusion: The use of the smartphone care management system demonstrated similar early outcomes to those achieved using traditional care models, along with a significant decrease in PT use. Noninferiority was demonstrated with regard to complications, readmissions, and ED and urgent care visits. This technology allows patients to rehabilitate on a more flexible schedule and avoid unnecessary healthcare visits, as well as potentially reducing overall healthcare costs.

Background: The thickness of the polyethylene bearing in medial unicondylar knee arthroplasty (UKA) is determined by the depth of the tibial resection, degree of correctable deformity, and balance of the knee. The purpose of this study is to evaluate whether polyethylene thickness in medial mobile-bearing UKA impacts clinical outcomes and survivorship.
Methods: A retrospective review from 2004 to 2017 identified patients who underwent a primary mobile-bearing medial UKA with 2-year minimum follow-up or revision. A total of 2305 patients (3030 knees) met inclusion criteria. Patients were divided in 2 groups: thin bearing (group 1): 3-mm or 4-mm bearing and thick bearing (group 2): ≥ 5 mm. The thin group consisted of 2640 knees (87%), whereas the thick group had 390 knees (13%). Preoperative and postoperative demographics, range of motion, Knee Society scores, complications, and reoperations were evaluated.
Results: Mean follow-up was 5.2 years (range, 0.5 to 12.6). There was no significant difference between groups in postoperative range of motion or Knee Society scores (P > .05). Manipulations were performed in 1.3% of patients and not significantly different between groups. The all-cause revision rate for group 1 was 4.02% and group 2 was 4.58% (P = .6). Revision rates for tibial aseptic loosening were significantly higher in group 2 (1.8%) than those in group 1 (0.7%) (P = .04). There was no significant difference in failure rates between groups for tibial collapse or fracture, femoral aseptic loosening, arthritic progression, bearing dislocation, or other cause of revision.
Conclusion: This study demonstrated that thicker bearings in medial UKA increased the risk of tibial aseptic loosening, but not all-cause failures or clinical outcomes.

Aims: A limited number of investigations with conflicting results have described perivascular lymphocytic infiltration (PVLI) in the setting of total knee arthroplasty (TKA). The purpose of this study was to determine if PVLI found in TKAs at the time of aseptic revision surgery was associated with worse clinical outcomes and survivorship.
Methods: A retrospective review was conducted on 617 patients who underwent aseptic TKA revision who had histological analysis for PVLI at the time of surgery. Clinical and radiological data were obtained pre- and postoperatively, six weeks postoperatively, and then every year thereafter.
Results: Within this cohort, 118 patients (19.1%) were found to have PVLI on histological analysis. Re-revision was performed on 83 patients (13.4%) with no significant differences in all-cause or aseptic revisions between groups. A higher incidence of PVLI was noted in female patients (p = 0.037). There was no significant difference in improvement in the range of motion (p = 0.536), or improvement of KSC (p = 0.66), KSP (p = 0.61), or KSF (p = 0.3) clinical outcome scores between PVLI and no PVLI sub-groups. There was a higher incidence of a preoperative diagnosis of pain in the PVLI group compared with patients without PVLI (p = 0.002) present.
Conclusion: PVLI found on large-scale histological analysis in TKAs at aseptic revision surgery was not associated with worse clinical outcomes or rates of re-revision. Cite this article: Bone Joint J 2021;103-B(6 Supple A):145-149.

Aims: The purpose is to determine the non-inferiority of a smartphone-based exercise educational care management system after primary knee arthroplasty compared with a traditional in-person physiotherapy rehabilitation model.
Methods: A multicentre prospective randomized controlled trial was conducted evaluating the use of a smartphone-based care management system for primary total knee arthroplasty (TKA) and partial knee arthroplasty (PKA). Patients in the control group (n = 244) received the respective institution’s standard of care with formal physiotherapy. The treatment group (n = 208) were provided a smartwatch and smartphone application. Early outcomes assessed included 90-day knee range of movement, EuroQoL five-dimension five-level score, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) score, 30-day single leg stance (SLS) time, Time up and Go (TUG) time, and need for manipulation under anaesthesia (MUA).
Results: Overall, 90-day mean flexion was not significantly different between the control (121° (SD 11.7°)) and treatment groups (121o; p = 0.559); 90-day mean SLS was 22.7 seconds (SD 9.8) in controls and 24.3 seconds (SD 20.8) in treatment (p = 0.519); 90-day mean TUG times were 10.1 seconds (SD 4.8) in control and 9.3 seconds (SD 3.3) in treatment (p = 0.139). Mean KOOS JR scores were significantly different between control group (73.6 (SD 13.4)) and treatment group (70.4 (SD 12.6); p = 0.026). MUAs were performed in nine (3.7%) patients in the control group and four (1.9%) in the treatment group (p = 0.398). Physiotherapy was performed by 230 (94.4%) of control group and 123 (59.3%) of treatment group (p < 0.001). There were no significant differences between groups in postoperative urgent care visits, or readmissions within 90 days, with significantly fewer emergency department visits in the treatment group (16 (8.2%) vs five (2.5%), p = 0.014).
Conclusion: The use of the smartwatch/smartphone care platform demonstrated non-inferiority of clinically significant outcomes to traditional care models, while requiring significantly less postoperative physiotherapy and fewer emergency department visits. This platform could aid in decreasing postoperative costs, while improving patient engagement and communication with the healthcare team. Cite this article: Bone Joint J 2021;103-B(6 Supple A):3-12.

The literature is mixed on the long-term fate of knees that undergo manipulation under anesthesia (MUA). The purpose of this study is to evaluate the long-term outcomes and survivorship of patients who required a MUA after primary total knee arthroplasty (TKA) compared with a cohort of patients who did not undergo a MUA. Between 2003 and 2007, 2,193 patients (2,783 knees) underwent primary TKA with 2-year minimum follow-up; 182 knees (6.5%) had a MUA. Patients who had a manipulation were younger (p < 0.001) and had worse preoperative range of motion (ROM) (p < 0.001). Postoperative ROM, Knee Society clinical (KSC), functional, and pain (KSP) scores, revisions, and survivorship were compared between MUA and no MUA. Mean follow-up was 9.7 years. MUA patients had lower postoperative ROM (p < 0.001), change in ROM (p < 0.001), KSC (p < 0.001), KSP (p < 0.001), and change in KSP scores (0.013). Revisions occurred in 18 knees (9.9%) in the MUA group compared with 77 knees (3%) without a MUA (p < 0.001). Most common reason for revision after MUA was continued stiffness (50%). Relative risk for revision after one MUA was 2.01 (95% confidence interval [CI], 1.1-3.8, p < 0.001) and after three or more MUAs were 27.02 (95% CI, 16.5-44.1, p < 0.001). Ten-year survival after MUA was 89.4% (95% CI, 87.1-91.7%) compared with 97.2% (95% CI, 96.9-97.5%) without a MUA (p < 0.001). Patients who undergo a MUA after primary TKA may have a knee at risk with higher revision rates, worse long-term clinical scores, ROM and survivorship.

Introduction: Revision knee systems have adapted to the challenges of revision knee arthroplasty with offset stems, augments, cones, and various levels of constraint. The purpose of this study is to review the mid-term outcomes of a second-generation modular knee revision system.
Materials and methods: A retrospective review was conducted from 2011 through 2014 on all patients who underwent knee arthroplasty with the Vanguard® 360 revision knee system (Zimmer Biomet, Warsaw, Indiana). Patients were included in the study if they were eligible for five-year minimum follow up and had signed a general research consent. The initial query revealed 253 patients (267 knees) that met inclusion criteria. Complications assessed were manipulation under anesthesia (MUA) and revision of any component. Statistical analysis using paired t-test was performed to evaluate changes in clinical outcomes and Kaplan-Meier survival analysis.
Results: Mean follow up was 6.6 years. The Vanguard® 360 knee system was used in four (1.5%) primary total knee arthroplasties (TKAs), 66 (24.7%) second-stage reimplantation TKAs after infection, and 197 (73.8%) aseptic revisions. There were significant improvements in knee range of motion and Knee Society Scores (all p<0.05). Manipulations under anesthesia were performed in 17 knees (6.4%). A total of 41 knees (15.4%) failed for any cause and required re-revision surgery. Of these, 11 (4.1%) failed due to aseptic loosening. Kaplan-Meier analysis revealed overall survival to endpoint of aseptic loosening to be 96.4% (95% CI: ±1.2%) at five years and 95.2% (95% CI: ±1.4%) at 9.5 years. When comparing survivorship in patients who underwent initial revision for aseptic indications compared with those whose underwent revision for second-stage reimplantation after infection, Kaplan-Meier survival to endpoint of revision for any cause at 9.5 years was higher for patients with aseptic than septic indication for TKA (87.0% [95% CI: ±2.4%] vs. 75.3% [95% CI: ±5.4%], p=0.0156).
Conclusion: The findings of this study demonstrate greater than 95% aseptic survivorship with the use of the Vanguard® revision knee system at mid-term follow up.
Background: Total hip arthroplasty (THA) continues moving to the outpatient arena, and may be feasible for some conversion and revision scenarios. Controversy surrounds appropriate patient selection. The purpose of this study is to report complications associated with outpatient revision and conversion THA, and to determine if comorbidities are associated with complications or overnight stay.
Methods: From June 2013 through August 2018, 46 patients (47 hips) underwent conversion (n = 10) or revision (n = 37) THA at a free-standing ambulatory surgery centre. This represented only 6.3% of revision THA cases at our institution during the study period that were selected for outpatient surgery. Mean patient age was 58.0 years, and 52% of patients were males. 1 or more major comorbidities were present in 15 patients (32%) including 1 valvular disease, 7 arrhythmia, 2 thromboembolism history, 3 obstructive sleep apnoea, 3 chronic obstructive pulmonary disease, 2 asthma, 4 frequent urination, and 1 renal disease.
Results: 44 (94%) patients were discharged same day without incident, none required transfer to acute facility, and 3 stayed overnight (2 convenience, 1 for medical reasons – urinary retention). The patient kept overnight for medical reasons had no major comorbidities. 3 patients were placed on an extended course of antibiotics, including 2 with positive intraoperative cultures and 1 for cellulitis. There were no major complications, readmissions, or subsequent surgeries within 90 days.
Conclusions: Outpatient revision hip arthroplasty is safe in selected patients undergoing minor or partial revisions. Presence of medical comorbidities was not associated with risk of complications. Medical optimisation and a multimodal programme to mitigate risk of blood loss and reduce narcotic need facilitate the safe performance of arthroplasty in an outpatient setting.

Adverse local tissue reactions (ALTRs) were initially reported as complications associated with metal-on-metal (MoM) bearings; however, there is increasing concern regarding the occurrence of adverse local tissue reactions from mechanically assisted crevice corrosion (MACC) at the femoral head-neck junction or between other modular junctions of the implant containing cobalt chromium parts in patients with metal-on-polyethylene (MoP) bearings. ALTR due to MACC at the head-neck junction has primarily been reported in association with cobalt chromium alloy femoral heads. As pain following total hip arthroplasty may have various intrinsic and extrinsic causes, a systematic approach to evaluation (risk stratification algorithm) based on the currently available data is recommended to optimize patient management. Evaluation should begin by ruling out common causes of pain, including component loosening and periprosthetic joint infection. While specialized tests such as blood metal analysis and metal artifact reduction sequence magnetic resonance imaging (MARS MRI) are useful modalities in evaluating for ALTRs, over-reliance on any single investigative tool in the clinical decision-making process should be avoided. There should be a low threshold to perform a systematic evaluation for ALTR due to MACC in patients with metal-on-polyethylene total hip arthroplasty as early recognition and diagnosis is critical, as delays in appropriate treatment initiation may result in soft-tissue damage, which complicates surgical treatment and is associated with a higher risk of complications and poorer patient outcomes.

Background: There has been increasing utilization of ultracongruent bearings with a cruciate retaining (CR) femoral component in primary total knee arthroplasty. The purpose of this study is to compare outcomes and survivorship between an ultracongruent anterior stabilized (AS) and CR bearing.
Methods: A retrospective review was performed from 2010 through 2014 of all primary total knee arthroplasties with a single knee systems identical CR femur and AS or CR bearing with minimum 2-year follow-up yielding a study cohort of 3323 patients (4164 knees). Knee range of motion, Knee Society pain scores, Knee Society clinical scores, Knee Society functional scores, and University of California Los Angeles activity scores were evaluated. The need for manipulation under anesthesia (MUA), nonrevision surgery and revisions were assessed.
Results: AS bearing was used in 1471 knees (35%) and CR bearing used in 2693 knees (65%). Mean follow-up was 5.4 years. The AS group had significantly higher improvements in knee range of motion, Knee Society clinical, Knee Society functional, and Knee Society pain scores. MUAs were performed on 120 knees (8.2%) in the AS group compared with 158 knees (5.9%) in the CR group (P = .005). The AS group had significantly less all-cause failure, aseptic failures, revisions for instability, and revisions for isolated polyethylene wear. The 10-year aseptic survival for AS was 98.3% and for 92.3% for the CR group (P = .002).
Conclusion: These mid-term results demonstrate the AS bearing had significantly higher improvements in clinical and functional outcomes as well as greater survivorship. Knees in which an AS bearing was used did have a higher incidence of MUA.

Background: The purpose of this study is to evaluate early postoperative surgical and medical complications in patients undergoing staged bilateral total knee arthroplasty (TKA) and determine if the interval to the second stage influences the risk of complications.
Methods: A retrospective review was performed from 2016 through 2018 of all staged bilateral primary TKA procedures, yielding a cohort of 1005 patients (2010 TKAs). Four groups were created based on the timing of the second stage: 3 to 6 weeks, 7 to 12 weeks, 13 to 24 weeks, and >24 weeks. Clinical data compared between groups included demographics, knee range of motion, University of California, Los Angeles (UCLA) activity score, Knee Society pain score, Knee Society clinical score, and Knee Society functional score. Postoperative complications within 90 days were evaluated, with complications after the second knee being the primary outcome.
Results: The mean follow-up after second stage was 10.7 months (range, 3 to 37 months). No significant differences were found between groups in the range of motion, Knee Society pain, Knee Society clinical score, Knee Society functional score, or University of California Los Angeles activity score in either the first or second knee. After the first knee surgery, medical complications were highest in the >24-week group. After the second knee, there were no significant difference in manipulation (P = .9), wound complications (P = .7), venous thromboembolism (P = .8), or other medical complications (P = 1) based on the interval duration.
Conclusion: The interval between staged TKA did not affect early medical or surgical complications after the second stage. Early clinical and function results were not different based on timing of the second surgery.

With the advances in perioperative care, rapid recovery protocols, and meticulous surgical technique, outpatient joint arthroplasty is a safe and effective option in many patients. To ensure the best outcome with minimal complications, patients must be properly medically optimized, be appropriately educated, and have adequate support at home. This combination of patient optimization must be combined with comprehensive rapid recovery protocols and multidisciplinary medical and anesthesia teams. Surgeons should use a multimodal pain control protocol, blood conservation, and minimally invasive techniques so that patients may be mobile hours after surgery with minimal complications.
Unicompartmental knee arthroplasty and patellofemoral arthroplasty were pioneered in the 1970s but abandoned by most in favor of total knee arthroplasty because of inconsistent early outcomes. Advancements in implant design, instrumentation, indications, and surgical techniques have enhanced results and led to a resurgence in both unicompartmental knee arthroplasty and patellofemoral arthroplasty for appropriate candidates. In appropriately selected patients, current implants and techniques provide surgeons the resources to carry out a surgical procedure that is simpler to perform and easier to recover from. Furthermore, unicompartmental knee arthroplasty is associated with fewer postoperative complications and lower mortality and is equal to or better than total knee arthroplasty.
Background: Total knee arthroplasty (TKA) is a common treatment for end-stage knee osteoarthritis but is associated with increased complication rates compared with unicompartmental knee arthroplasty (UKA). UKA offers better functional outcomes but is associated with a higher risk of revision. The purpose of this study was to apply good-practice, stated-preference methods to quantify patient preferences for benefit-risk tradeoffs associated with arthroplasty treatments for end-stage knee osteoarthritis.
Methods: A discrete-choice experiment was developed with the following attributes: chance of complications, functional ability, awareness of the knee implant, and chance of needing another operation within 10 years. Patients included those aged 40 to 80 years with knee osteoarthritis. A pivot design filtered respondents into 1 of 2 surveys on the basis of self-reported functional ability (good compared with fair or poor) as measured by the Oxford Knee Score. Treatment-preference data were collected, and relative attribute-importance weights were estimated.
Results: Two hundred and fifty-eight completed survey instruments from 92 males and 164 females were analyzed, with 72 respondents in the good-function cohort and 186 in the fair/poor-function cohort. Patients placed the greatest value or relative importance on serious complications and rates of revision in both cohorts. Preference weights did not vary between cohorts for any attribute. In the good-function cohort, 42% of respondents chose TKA and 58% chose UKA. In the fair/poor-function cohort, 54% chose TKA and 46% chose UKA.
Conclusions: Patient preferences for various treatment attributes varied among patients in a knee osteoarthritis population. Complication and revision rates were the most important factors to patients, suggesting that physicians should focus on these areas when discussing treatments. The proportion of patients who chose UKA suggests that the current trend of increased UKA utilization is aligned with patient preferences.
Clinical relevance: Systematic elicitation of patient preferences for knee arthroplasty procedures, which lays out evidence-based risks and benefits of different treatments, indicates a larger subset of the knee osteoarthritis population may prefer UKA than would be suggested by the current rates of utilization of the procedure. Arthroplasty treatment should align with patient preferences and eligibility criteria to better deliver patient-centered care.
Background: Most implants for total knee arthroplasty (TKA) are comprised of alloys that contain nickel. Controversy exists whether metal allergies produce negative effects and affect clinical outcomes. The purpose of this study was to retrospectively review a minimum 2-year follow-up with an ion-bombarded titanium TKA implant in patients with reported metal sensitivity.
Methods: A retrospective review of patients who underwent primary TKA with the ion-bombarded titanium Vanguard (Zimmer Biomet, Warsaw, IN) implant with 2-year minimum follow-up was performed from 2008 through 2017. The query revealed 346 patients (451 knees) with minimum 2-year follow-up. The mean age was 64.7 years, the mean body mass index was 35.1 kg/m2, and 95% of patients were women.
Results: The mean follow-up was 4.6 years. The mean range of motion improved from 109° to 112° (P = .03), University of California Los Angeles activity scale from 4.1 to 5.1 (P < .001), Knee Society Clinical scores from 36 to 89 (P < .001), and Knee Society Functional scores from 48 to 73 (P < .001). There were 5 (1.1%) revisions: 2 infections (2-staged exchange), 1 tibial revision for aseptic loosening after a fall, and 2 bearing exchanges for instability. Other surgeries were open reduction internal fixation of periprosthetic fracture, 1 arthroscopic release of snapping popliteus, and 4 local wound incision and debridement (2 superficial infections and 2 nonhealing wounds). Manipulation under anesthesia was required in 27 (6%) patients.
Conclusions: These early results are encouraging for the use of alternative metal titanium alloy implants in metal-sensitive patients undergoing primary TKA. At 4.6 years of mean follow-up, patients had substantial improvement in the range of motion and clinical outcomes with a low frequency of revision.

Polyethylene wear and osteolysis has long been an issue with the survivorship of total hip arthroplasty. The purpose of this study was to assess the survivorship after isolated liner exchange with the use of the RingLoc acetabular cup. A query of our practice registry revealed 106 patients (112 hips) with a single cementless titanium plasma sprayed acetabular component (RingLoc, Zimmer Biomet, Warsaw, IN), who underwent acetabular liner exchange for treatment of polyethylene wear between January 2001 and March 2015. Eighty patients (85 hips) met inclusion criteria. Clinical outcomes were assessed with the Harris hip score and radiographic evaluation was performed. The mean follow-up after liner exchange was 6 years (range, 2-15.7 years). Harris hip scores improved from 70.9 (range, 28-100) preoperatively to 79 (range, 29-100) at most recent evaluation (p < 0.001). Subsequent surgery was required in 11 patients (11 hips, 13%). Components were revised in 7 hips (8.2%). One acetabular revision was performed for aseptic loosening and four for instability (4.7%). One metal-polyethylene sandwich liner was revised for metal hypersensitivity. One patient underwent two-staged exchange for infection. In our early to mid-term experience with the RingLoc acetabular cup, isolated liner exchange for treatment of polyethylene wear yielded 98.8% acetabular survival for aseptic loosening at up to 15 years.

Background: The purpose of this study is to review the incidence of symptomatic venous thromboembolism (VTE) in patients undergoing outpatient primary total knee arthroplasty (TKA) who used a portable pneumatic compression device as part of their VTE prophylaxis protocol.
Methods: A retrospective review of all outpatient primary TKA procedures in which patients used ambulatory pneumatic compression pumps as part of their multimodal VTE prophylaxis was performed from 2016 through 2018. This yielded a cohort of 1131 patients (1453 TKAs). An aspirin (ASA)-based protocol was used in patients with standard VTE risk receiving either 81 mg or 325 mg of ASA twice daily for 6 weeks postoperatively. High-risk patients received a stronger chemoprophylaxis for 2 weeks followed by ASA for 4 weeks. Pneumatic compression pumps were worn for 23 hours/day for 14 days.
Results: VTE prophylaxis medication was 81-mg ASA in 56% of patients, 325-mg ASA in 10% of patients, and stronger chemoprophylaxis in 34% of patients. Patients were considered morbidly obese (body mass index >40 kg/m2) in 267 (18.4%) procedures. Ninety-seven (6.7%) patients had a preoperative history of VTE event. Forty-nine duplex ultrasounds were performed (3.3% of TKAs). Confirmed VTE events were documented in only 5 (0.3%) patients. All VTEs occurred in high-risk patients who were discharged on stronger chemoprophylaxis. The time (days) to VTE was 3, 3, 7, 45, and 88 days.
Conclusion: The use of portable pneumatic compression pumps as part of a multimodal VTE prophylaxis protocol aided in a very low rate of symptomatic VTE events in patients undergoing outpatient primary TKA.

Background: The shift toward outpatient joint arthroplasty is rapidly growing, but concerns still remain on whether certain patients should be excluded from same-day discharge arthroplasty. The purpose of this study is to evaluate whether morbid obesity is a risk factor for perioperative complications after outpatient joint arthroplasty.
Methods: A retrospective review was performed from 2013 to 2017 of all outpatient primary total hip, total knee, partial knee, and revision hip and knee arthroplasties, yielding a cohort of 4863 patients (5988 arthroplasty procedures). Patients were separated and analyzed based on 2 groups: nonmorbidly obese (NMO) (BMI < 40 kg/m2) and morbidly obese (MO) (BMI ≥ 40 kg/m2). The NMO group consisted of 4870 arthroplasties and the MO group consisted of 1118 arthroplasties. Overnight stays, medical complications, and early perioperative complications were assessed between groups.
Results: Overnight stays occurred in 5.4% of NMO patients and 9.1% of MO patients (P < .001), with medical reasons for the overnight stay occurring in 3.2% of NMO and 6.4% of MO patients (P < .001). Respiratory/sleep apnea was the leading medical reason leading to overnight stay occurring in 4% of MO patients and 0.8% of NMO patients (P < .001). There was no significant difference between groups in direct facility transfers, emergency room visits/admissions, or medical complications within 90 days. Wound revisions, nonrevision surgery, or revisions within 90 days were significant between groups.
Conclusion: MO patients did not have an increased risk of 90-day medical complications, readmission, or revisions after outpatient arthroplasty. However, MO patients did have a significantly higher incidence of overnight stay.

The purpose of this study is to determine if a fellow’s involvement, as well as duration of a fellow’s training, impacts complications, outcomes, and survivorship in primary total knee arthroplasty (TKA). A retrospective review identified 2,790 consecutive patients (3,530 knees) who underwent primary TKA between 2003 and 2008. A 2-year minimum follow-up was available on 2,785 knees (2,195 patients). Operative data, clinical outcomes, complications, and survivorship were compared between cases with and without a fellow involved as well as comparing cases in the first quarter (Q1) of the academic year to the last three quarters (Q2-4). Mean follow-up was 9.7 years. Fellows were involved in 1,434 (41%) surgeries. Fellow cases had significantly longer tourniquet times (59.5 vs. 49 minutes, p < 0.001) and operative times (82.4 vs. 70.8 minutes, p < 0.001). Overall, there was no difference in clinical, functional, or pain outcomes between attending and fellow cases. Fellow cases during Q1 had significantly worse pain scores (p = 0.009) and clinical scores (p < 0.001). Revision rate, infection rates, and survivorship were not significantly different between fellow and attendings or during Q1 of fellowship compared with attendings. Primary TKA survivorship and complications were not affected by fellow involvement or academic quarter. An “August Effect” may be suggested for clinical and pain outcomes in the first 3 months of fellowship.

Background: As total knee arthroplasty (TKA) continues moving to the outpatient arena, the demand for revision surgery will subsequently increase which draws into question the feasibility for some revision scenarios as an outpatient. The purpose of this study is to report on the safety of outpatient revision knee arthroplasty.
Methods: From June 2013 through December 2018, 102 patients (106 knees) underwent revision knee arthroplasty at a free-standing ambulatory surgery center. Mean patient age was 58.0 years, and 43% of patients were male. Procedures included the following: 45 cases of unicompartmental arthroplasty to TKA, 54 TKA revisions, and 52 cases involved a full exchange of components.
Results: Ninety-three patients (88%) were discharged the same day without incident, none required transfer to acute facility, and 13 required overnight stay with 4 of these for convenience and 9 for medical reasons. There were no major complications within the first 48 hours postoperative. One patient required readmission for treatment of ileus 11 days postoperative. There were no other readmissions, no subsequent surgeries, and no deaths within 90 days. One or more major comorbidities were present in 66 patients.
Conclusion: Outpatient revision knee arthroplasty was found to be safe in carefully selected patients and case scenarios. Presence of medical comorbidities was not associated with risk of complications. The paradigm changes of patient education, medical optimization, and a multimodal program to mitigate the risk of blood loss and reduce need for narcotics facilitates performing some revision arthroplasties safely in an outpatient setting.

Background: At the turn of the 21st century, there was a re-emergence of metal-on-metal (MoM) articulation with 35% of all total hip arthroplasty implants having MoM articulation. Approximately 10 years after its peak use, MoM articulation began to decrease dramatically as revisions became more apparent because of adverse reaction to metal debris. Today, there are surveillance guidelines and reconstructive clinical pearls a surgeon should recognize.
Methods: This article gives a literature-based overview of clinical pearls and discusses how to avoid pitfalls when performing revision of a metal-on-metal total hip arthroplasty.
Results: Patients with MoM can be risk-stratified based on symptom, implant, and testing variables. Those patients who are symptomatic and/or develop adverse reaction to metal debris with local tissue destruction will require a revision. The revision of MoM can be challenging due to bone and soft tissue destruction. Constraint may be needed in cases of abductor deficiency.
Conclusion: Although MoM implants for THA have declined significantly, surgeons are still faced with the revision burden from a decade of high use. Risk stratification tools are available to aid in revision decision making, and the surgeon should be prepared to address the challenges these revisions present.

Background: The opioid epidemic has created a national healthcare crisis, and little is known about the accuracy of self-reported narcotic usage in arthroplasty. The purpose of this study is to evaluate the accuracy of self-reported opioid usage in patients undergoing outpatient arthroplasty.
Methods: A retrospective review was conducted on all primary unilateral arthroplasty procedures performed in 2018 at a free-standing ambulatory surgery center, yielding a cohort of 959 arthroplasties. Patient’s prescription records were queried in the Ohio Automated Rx Reporting System for 3 months before surgery and minimum 9 months after surgery. These data were cross-referenced against the patient-reported preoperative use of narcotics. Three groups were evaluated: (G1) no preoperative narcotics, (G2) accurately self-reported on narcotics, and (G3) on narcotics but did not disclose.
Results: One hundred fourteen patients (12%) were on preoperative opioids based on the Ohio Automated Rx Reporting System query, with only 35 of these patients (31%) self-reporting. G2 had significantly lower postoperative knee range of motion, Knee Society Pain score, Knee Society Clinical score, Knee Society Functional score, Harris Hip Score, and University of California Los Angeles activity scores than G1. Overnight stays occurred in 1.2% of patients in G1, 3% of patients in G2 (P = .5), and 6.3% of patient in G3 (P = .002). All aspects of postoperative narcotic use were significantly higher in G2 and G3 compared to G1. The relative risk for narcotic refill after 90 days in G2 was 4.6 (95% confidence interval 3.7-5.8, P < .001).
Conclusion: The majority of patients on preoperative narcotics did not disclose their use. Patients on narcotics preoperatively had significantly greater postoperative narcotic use including refills, total morphine milliequivalent, and risk of being on narcotics 90 days after surgery.

Introduction: With the growing demand for total knee arthroplasty (TKA), the burden of revision surgery will continue to rise. Revision knee arthroplasty has historically had worse survivorship than primary knee arthroplasty. The purpose of this study is to review the 10-year outcomes and survivorship of a modular revision knee system.
Materials and methods: A retrospective review was conducted on 109 patients (117 knees) who underwent a revision knee arthroplasty with the Vanguard® Super Stabilized Knee (SSK) Revision System (Zimmer Biomet; Warsaw, Indiana) who were eligible for 10-year minimum follow up. Clinical and radiographic data was obtained pre- and postoperatively, six weeks postoperatively, and then every year thereafter.
Results: With an average follow up of 10.7 years (range, 2.3 to 14.1 years), the SSK revision system exhibited a notable improvement in both clinical and functional outcomes. Average knee range of motion improvement was 4.2 degrees (SD ±18). Manipulations under anesthesia were performed in six knees (5%). Re-revisions occurred in 27 knees (23%). Ten of the re-revisions were for aseptic loosening (37%), eight for periprosthetic infection (30%), five for instability (19%), and the remainder for other aseptic causes. Mean time to failure was 4.6 years (range, 1 to 9.1 years). The 10-year all-cause survival was 77% (95% confidence interval [CI], 73 to 81%). The 10-year aseptic survival was 83% (95% CI, 79 to 87%).
Conclusion: The findings of this study show an 83% 10-year aseptic survivorship with the Vanguard® SSK knee revision system. These results are comparable to long-term follow up of other revision knee systems.
Introduction: Patellar resurfacing in primary total knee arthroplasty (TKA) remains a controversial topic. The purpose of this study is to evaluate whether patellar resurfacing affects early complications and outcomes with a symmetric femoral component design.
Materials and methods: Retrospective review was performed from 2015 to 2019 of all primary TKAs performed with the Klassic® Knee System (Total Joint Orthopedics, Inc., Salt Lake City, Utah) yielding a cohort of 526 patients (674 knees). Patients were compared based on whether the patella was resurfaced (391 knees, 58%) or unresurfaced (283 knees, 42%). Pre- and postoperative range of motion (ROM), University of California Los Angeles (UCLA) activity score, and Knee Society clinical (KSC), functional (KSF) and pain (KSP) scores were assessed between groups. Manipulation under anesthesia (MUA) and revisions were evaluated. The resurfaced group was significantly younger and had significantly more female patients, but they had no differences in preoperative body mass index (BMI), knee ROM, or Knee Society scores. One-year minimum follow up was available in 240 patients.
Results: Mean follow up was seven months (range, 1 to 35 months, SD ±7 months). MUAs were performed on 12 knees (4.2%) in the unresurfaced group and 37 knees (9.5%) in the resurfaced group (p=0.01). One patient (0.3%) in the unresurfaced group underwent a revision 1.5 years after the index surgery for a patellar resurfacing and polyethylene exchange. No other revisions were performed in either group. In patients with one-year minimum follow up, there was no significant difference in ROM or clinical or functional outcomes between groups.
Conclusion: Patients who underwent a primary TKA with the TJO Klassic® Knee System with a resurfaced patella had a significantly higher incidence of manipulation under anesthesia than those with an unresurfaced patella. At most recent follow up, there was no significant difference in mean ROM or clinical outcome scores.
Background: The effect of age on the percentage of primary knee replacements appropriate for unicompartmental replacement (UKR), defined as candidacy, is unknown. The aim was to determine the candidacy and outcome of UKR in different age groups.
Hypothesis: Age is associated with candidacy for medial UKR.
Patients and methods: This cross-sectional study determined UKR candidacy from preoperative radiographs, including stress views, from 457 consecutive knee replacements (TKR or UKR) in a specialist joint replacement centre. Candidacy, estimated from radiographs and from usage, was determined for all knees and then stratified by age group<50, 50-60, 60-70, 70-80, and 80+. The outcome of UKR implanted in these groups was also assessed. To avoid overestimating, candidacy estimated by usage was used for the primary analysis.
Results: Candidacy decreased with age (OR 0.98, p=0.008) and was 61% (CI 42-78), 52% (CI 43-61), 43% (CI 35-51), 41% (CI 31-52), and 36% (CI 22-52) respectively. Candidacy estimated by radiographs was slightly higher overall (49% compared to 46%) and in all age groups than candidacy estimated from usage. Neither functional outcome (p=0.47) nor implant survival (p=0.54) was affected by age. Overall 80% achieved good/excellent Knee Society objective scores, and the five-year implant survival was 99%.
Discussion: There is a strong association of candidacy for UKR with age in that younger patients are more likely to be candidates (61% in those<50 and 36% in those 80+). Good outcomes can be expected in patients of all ages who are appropriate for UKR.

Purpose: The primary purpose of this study is to report the incidence of complications associated with outpatient total knee arthroplasty (TKA). Secondarily, 2-year minimum outcomes are reported.
Methods: Between 2013 and 2016, 928 patients underwent 1143 outpatient TKAs with the Vanguard Complete Knee System (Zimmer Biomet, Warsaw, IN). Patients were selected for outpatient surgery if they were medically optimized without a failing organ system and had sufficient support at home. Overnight stays, medical complications and early perioperative complications were assessed in this entire cohort. Two-year minimum follow-up was available on 793 patients (978 knees). Patient records were analyzed for outcome measures and revisions.
Results: In 124 procedures, the patient stayed overnight for 23-h observation. Thirty-seven (3.2%) were for convenience reasons and 87 (7.6%) for medical observation. Heart disease and chronic obstructive pulmonary disease were associated with increased risk of overnight stay. Excluding manipulations, reoperation within 90 days occurred in eight (0.7%) knees. Patients with 2-year minimum follow-up had significant improvements in ROM, Knee Society Clinical, Functional and Pain scores (p < 0.005). Nine (0.8%) patients required revision. Manipulations were performed on 118 (10.3%) patients. The overall deep infection rate was 0.17% (2/1143).
Conclusions: Outpatient TKA is safe for a large proportion of patients. Certain medical co-morbidities increase the risk of overnight stay. Patients had significant improvement in ROM and outcome scores with low revision rate.
Level of evidence: III.

Background: Thigh pain following a well-fixed total hip arthroplasty (THA) remains problematic and a source of patient dissatisfaction. The purpose of this study is to evaluate if the development of distal femoral cortical hypertrophy (DFCH) is associated with postoperative thigh pain after THA.
Methods: All patients who underwent an uncomplicated primary THA via a direct anterior approach with the Taperloc Microplasty (Zimmer Biomet, Warsaw, IN, USA) implant between 2011 and 2015 were mailed a pain drawing questionnaire. Radiographs were reviewed at 1 year minimum to determine cortical thickness change from immediate post-op. Thigh pain was compared to DFCH. 293 patients were included in the study.
Results: Mean follow-up was 3.2 years. A total of 218 hips (74%) had cortical hypertrophy in Gruen zone 3 and 165 hips (56%) had cortical hypertrophy in Gruen zone 5. 52 hips (18%) had ⩾25% cortical hypertrophy in zone 3 and 91 hips (31%) had ⩾25% cortical hypertrophy in zone 5. A total of 44 patients (15%) reported anterior thigh pain and 43 patients (15%) reported lateral thigh pain. Development of DFCH in either Gruen zone 3 or 5 was not associated with anterior or lateral thigh pain. Stem size was positively correlated with zone 3 hypertrophy and inversely related to zone 5 hypertrophy. Thigh pain was not associated with patient age, gender, activity level or stem size.
Conclusions: The development of distal femoral cortical hypertrophy after THA with a short stem implant was high, but not associated with patient-reported anterior or lateral thigh pain.

Background: Recurrent instability after total hip arthroplasty is a difficult complication. In certain cases, a constrained acetabular device is needed to address these issues. The purpose of this study is to report the midterm outcomes and survivorship of a single novel constrained liner device.
Methods: A retrospective review as performed on all procedures (except first stage exchange for infection) in which a Freedom Constrained (Zimmer Biomet, Warsaw, IN) liner was used between December 2003 and November 2016. Patients with 2-year minimum follow-up or failure were included, yielding a cohort of 177 patients. Procedures were 130 aseptic revisions, 40 reimplantations following infection eradication, and 7 complex primaries. The constrained mechanism was implanted in 46 hips (26%) to treat active instability and 131 hips (74%) for increased risk of instability and intraoperative instability. Patients had on average 3.4 previous surgeries.
Results: With an average 7.1-year follow-up, 11 hips dislocated (6.2%), and 13 hips (7.3%) were revised for acetabular aseptic loosening, resulting in an overall constrained aseptic or mechanical failure rate of 13.6%. Nineteen hips (10.7%) failed from infection with 58% of these having had a previous infection. Patients with active instability had significantly higher failure for dislocation than patients who were at risk (15.2% vs 3%, P = .01). All-cause survival rate at 7 years was 74.8%, aseptic survival was 83.6%, and survival for instability was 91.8%.
Conclusion: Revision for instability remains challenging as many patients have had numerous previous surgeries and at-risk anatomy. Constrained inserts are one option to manage instability, but a high rate of recurrence can still occur.

Unicompartmental knee arthroplasty (UKA) is a treatment option for anteromedial osteoarthritis. Compared with total knee arthroplasty (TKA), UKA offers improved knee range of motion, functional recovery and decreased medical complications. Revision rates continue to be higher with UKA compared with TKA. With current UKA implants, there is no significant difference in mobile bearing or fixed bearing, or between cemented and cementless implants. Enabling technology, such as robotic-assisted surgery, has demonstrated improvements in component positioning, but no long-term difference in survival compared with traditional manual instruments.

Background: The impact of a patient’s activity level following total knee arthroplasty (TKA) remains controversial, with some surgeons concerned about increased polyethylene wear, aseptic loosening, and revisions. The purpose of this study is to report on implant survivorship and outcomes of high activity patients compared to low activity patients after TKA.
Methods: A retrospective review identified 1611 patients (2038 knees) that underwent TKA with 5-year minimum follow-up. Patients were divided in 2 groups based on their University of California Los Angeles (UCLA) activity level: low activity (LA) (UCLA ≤5) and high activity (HA) (UCLA ≥6). Outcomes included range of motion, Knee Society scores, complications, and reoperations. Parametric survival analysis was performed to evaluate the significance of activity level on survivorship while controlling for age, gender, preoperative pain, Knee Society clinical scores, Knee Society functional scores, and body mass index (BMI).
Results: Mean follow-up was 11.4 years (range 5.1-15.9). The LA group had significantly more female patients, were older, had higher BMI, and had lower functional scores preoperatively (all with P < .001). The HA group had significantly higher improvements in Knee Society scores (P < .001) and pain postoperatively (P < .001). Revisions were performed in 4% of the LA group and 1.7% knees of the HA group (P = .003). After controlling for age, gender, preoperative pain, Knee Society clinical scores, Knee Society functional scores, and BMI, a higher postoperative activity level remained a significant factor for improved survivorship with an odds ratio of 2.4 (95% confidence interval 1.2-4.7, P = .011). The all-cause 12-year survivorship was 98% for the HA group and 95.3% for the LA group (P = .003). The aseptic 12-year survivorship was 98.4% for the HA group and 96.3% for the LA group (P = .02).
Conclusion: Highly active patients had increased survivorship at 5-year minimum follow-up compared to lower activity patients after TKA. Patient activity level after TKA may not need to be limited with modern implants.
