Patellar tendinitis is an injury that affects the tendon connecting your kneecap (patella) to your shinbone. The patellar tendon plays a pivotal role in the way you use your legs. It helps your muscles extend your lower leg so that you can kick a ball, push the pedals on your bicycle and jump up in the air.
Patellar tendinitis is most common in athletes whose sports involve frequent jumping — for instance, basketball, soccer and volleyball players. For this reason, patellar tendinitis is commonly known as jumper's knee. However, anyone can suffer from patellar tendinitis, whether a frequent jumper or not.
For most people, treatment of patellar tendinitis begins with conservative approaches.
