Patellar tendonitis is irritation of the tendon that connects the kneecap to the shinbone. It is often called jumper’s knee. It commonly causes pain at the front of the knee during running, jumping, or squatting.

What causes patellar tendonitis?

It is usually caused by repetitive jumping, sprinting, or rapid increases in training load. Weakness, tightness, and poor landing mechanics can contribute. Basketball, volleyball, soccer, and track athletes are commonly affected.
