Patellar Tendonitis (Jumper’s Knee): Causes, Symptoms And Treatment

Tendonitis can affect many joints in the body, but the knee is especially prone to this painful inflammation. Repetitive movements such as running, jumping, and squatting can cause nagging irritation known as patellar tendonitis. In this video, Dr. Shane Arnold explains how Airrosti’s method differs from traditional tendonitis treatment. By treating pain directly at the source, we get you back doing what you love, fast.

The patellar tendon plays a pivotal role in the way you use your leg muscles. It helps your muscles extend your knee so that you can kick a ball, run uphill and jump up in the air. Patellar tendonitis is a common overuse injury, caused by repetitive stress on your patellar tendon. The stress results in tiny tears in the tendon, which your body attempts to repair. But as the tears in the tendon multiply, they cause pain from inflammation and weakening of the tendon.

This condition is most often seen in athletes who do repetitive jumping, the reason patellar tendonitis is often called “jumper’s knee.” Patellar tendonitis is most often seen in participants of sports including basketball and volleyball, although can also be seen in runners and other types of athletes. It accounts for about 5% of all running injuries.

Pain is the first symptom of patellar tendonitis, usually between your kneecap and where the tendon attaches to your shinbone (tibia). The pain in your knee may at first be present only as you begin physical activity or just after an intense workout. It may worsen until it begins to interfere with your ability to play your sport. Eventually, it will interfere with daily movements such as climbing stairs or rising from a chair.

If you try to work through your pain, ignoring your body’s warning signs, you could cause increasingly larger tears in the patellar tendon. Knee pain and reduced function can persist if you don’t tend to the problem, and you may progress to the more serious patellar tendinopathy.


Patellar tendonitis can worsen without proper treatment. It will eventually result in degeneration of the tendon. This condition is common in many athletes and affects more than 20 percent of all jumping athletes. Full recovery takes anywhere from six to 12 months after physical therapy. Your doctor may prescribe over-the-counter pain relievers, a patellar tendon strap, or cortisone injections. In rare cases, surgery may be recommended. You will be required to stay off the knee as much as possible while it heals, significantly limiting your activity.

Airrosti can help rapidly speed recovery, allowing you to maintain your active lifestyle and continue any athletic activities. Through our highly targeted, noninvasive manual therapy and active recovery program, we can often resolve your injury in as few as three visits based on patient-reported outcomes, and most individuals can resume normal activity right away.
