Patellar Tendonitis: Understanding Jumper’s Knee and How to Treat It

What is Jumper’s Knee (Patellar Tendonitis)?

Patellar tendonitis (sometimes called jumper’s knee) is an overuse injury that causes knee pain and inflammation in the patellar tendon, the tissue that connects your kneecap (patella) to your shin bone. When the patellar tendon connects these structures, it allows the quadriceps muscles in the thigh to straighten the leg during running, kicking, or jumping.

Over time, repeated stress on the tendon can cause tiny tears, leading to pain, swelling, and reduced performance. This condition is also referred to as patellar tendinopathy when there is ongoing tendon degeneration rather than just inflammation.

Symptoms of Jumper’s Knee

Jumper’s knee symptoms often begin gradually and worsen over time. Common signs include:

  • Pain just below the kneecap that increases with physical activity
  • Tenderness and swelling around the tendon
  • Discomfort when pressing on the tendon
  • Pain that worsens with jumping, squatting, or climbing stairs
  • Difficulty with daily activities if the injury becomes severe
 

Causes and Risk Factors of Patellar Tendonitis

Patellar tendonitis develops when the stress on the patellar tendon exceeds its ability to heal. This can result in small tears that progress to chronic tendon damage.

Common causes:

  • Overuse from jumping sports or intense training
  • Sudden increase in physical activity or starting a new sport without proper conditioning
  • Performing activities on hard surfaces
 

Key risk factors include:

  • It is common in athletes, especially those in high jump, basketball, or volleyball
  • Weak or imbalanced thigh muscles
  • Tight thigh muscles
 

Diagnosis of Patellar Tendonitis

To diagnose patellar tendinitis, a physician will review your medical history, assess your symptoms, and perform a physical exam to check for tenderness along the tendon.

Imaging tests may be used for a more detailed evaluation:

  • Magnetic resonance imaging (MRI) can reveal tiny tears, swelling, and tendon degeneration.
  • Ultrasound may show changes in the tendon’s structure.
 

How is Patellar Tendonitis Treated?

The goal of treatment is to reduce pain, promote healing, and restore strength. Options may include:

  • Rest and modification of activities to reduce tendon stress
  • Bracing or taping for support
  • Ice and anti-inflammatory medications for swelling and inflammation
  • Physical therapy focused on stretching and strengthening exercises
  • Sports medicine techniques, like eccentric strengthening exercises for tendon rehabilitation
  • Steroid injections
  • In severe cases, surgery may be necessary to repair a rupture or persistent tendon damage
 

At JIS Orthopedics, our specialists tailor each treatment plan to your individual needs, helping you safely and gradually increase activity while reducing the risk of further injury.

Complications of Jumper’s Knee

If left untreated, patellar tendon strain can lead to:

  • Chronic pain that limits sports and daily activities
  • Larger patellar tendon tears
  • Long-term tendinitis that weakens the tendon and increases the chance of reinjury
  • Difficulty participating in physical activity due to persistent discomfort
 

Can Patellar Tendonitis Be Prevented?

While not every case is preventable, certain steps can reduce the risk of developing jumper’s knee:

  • Warm up before activity and stretch after exercise
  • Strengthen the quadriceps and supporting muscles
  • Avoid sudden increases in training intensity; gradually increase load
  • Cross-train with low-impact activities to give the tendon time to heal
