What is Osgood-Schlatter Disease?
Osgood-Schlatter disease is a painful enlargement of the bump of the shin bone (tibia) just below the knee. This bump is called the tibial tuberosity. The tendon from the kneecap (patella) inserts here. Osgood-Schlatter disease is commonly seen in growing (usually appears during a period of rapid growth), active adolescents, and most often seen in children between the ages of 10 and 15.
