Patellar tendinitis is a common overuse injury. It occurs when you place repeated 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 become more numerous, they cause pain from inflammation and a weakening of the tendon structure. When this tendon damage persists over more than a few weeks, it is called tendinopathy.
