Patellar tendinitis

Fact Checked

Patellar tendinitis is an injury caused on the tendon that attaches the kneecap or patella to the shinbone. The patellar tendon is located at the front of the thigh that functions in extending the knee to help with kicking, jumping and running. Patellar tendinitis is also called jumper’s knee and common in athletes that play sports that require frequent jumping such as volleyball and basketball, but those who do not participate in any jumping sports can also be affected by patellar tendinitis.

Patellar tendinitis is an overuse injury that can be caused by repeated stress on the patellar tendon and this stress will cause small tearing of the tendon which the body tries to repair. As the tearing of the tendon becomes bigger, it will cause inflammation and weakening of the tendons. When the damage on the tendon persists for more than a week, it is called tendinopathy.
