Runner’s knee or patellofemoral pain syndrome differ from patellar tendonitis. In patellar tendonitis, the tendon which is connecting kneecap and shin bone of the lower limb. Patellofemoral pain syndrome gets its name from the relevant anatomy around the knee. : the cause of the pain is the kneecap—the patella—rubbing against the groove in the femur, where it slides back and forth when you flex and extend the knee.
