Patellar Tendinitis

The patellar tendon connects the kneecap (patella) to the shin bone (tibia). It plays an important role in the way you use your legs. It helps your thigh muscles (quadricepts) straighten your knee.

The patellar tendon is made of tough string-like bands which are surrounded by a membrane that helps it to glide.

Patellar tendonitis is a condition that occurs when the tendon and membrane becomes inflammed.

It is usually an overuse injury, commonly associated with jumping activities. Which is why it is often called "jumper's knee". It is most common in athletes whose sports involve frequent jumping — for example, basketball and volleyball players. However, anyone can suffer from patellar tendinitis.

Alternate name

  • jumper's knee
