Introduction

Patellar tendinitis, also called jumper’s knee, occurs when the tendon connecting the kneecap (patella) to the shinbone becomes irritated or inflamed. This condition is common in athletes and active individuals who do a lot of jumping, running, or sudden changes of direction. Early treatment can reduce pain, improve function, and help prevent long-term issues.

What is Patellar Tendinitis?

Patellar tendinitis is inflammation or microtears in the tendon just below the kneecap. Overuse or repeated stress can irritate the tendon, leading to pain, swelling, and stiffness. The condition often develops gradually, with discomfort increasing during physical activity.

How Do I Know if I Have Patellar Tendinitis?

Typical signs of patellar tendinitis include:

Pain directly below the kneecap, especially during activity
Swelling or tenderness over the tendon
Stiffness in the knee, especially in the morning or after sitting
Pain that worsens with jumping, running, squatting, or climbing stairs
Weakness in the quadriceps muscles

Early recognition and treatment are important to prevent worsening of the tendon damage.

Treatments for Patellar Tendinitis

Most cases improve with non-surgical treatment, including:

Rest and activity modification to reduce strain on the tendon
Ice and anti-inflammatory medications to relieve pain and swelling
Physical therapy to strengthen the quadriceps, improve flexibility, and correct movement patterns
Bracing or taping to support the tendon during activity
Gradual return to sport under the supervision of a healthcare provider

Surgery is rarely needed and is reserved for persistent cases that do not respond to conservative care.

Do I Need Surgery?

Surgery may be recommended if symptoms persist despite conservative treatment or if the finger continues to lock or catch. Surgical release involves opening the tendon sheath to allow the tendon to glide smoothly. The procedure is typically quick and effective, restoring full motion to the finger.

Recovery and Prevention

Recovery from patellar tendinitis can take several weeks to months, depending on the severity. Physical therapy is key to restoring strength and preventing recurrence. Gradual progression of activity, proper warm-up, and attention to technique can reduce the risk of future tendon problems.
