Osgood-Schlatter disease is a common cause of knee pain in growing adolescents. It is an inflammation of the area just below the knee where the tendon from the kneecap (patellar tendon) attaches to the shinbone (tibia).

Osgood-Schlatter disease most often occurs during growth spurts, when bones, muscles, tendons, and other structures are changing rapidly. Because physical activity puts additional stress on bones and muscles, children who participate in athletics — especially running and jumping sports – are at an increased risk for this condition. However, less active adolescents may also experience this problem.

In most cases of Osgood-Schlatter disease, simple measures like rest, over-the-counter medication, and stretching and strengthening exercises will relieve pain and allow a return to daily activities.
