What is Osgood-Schlatter disease?
Osgood-Schlatter (say: "oz-good shlot-ter") disease is one of the most common causes of knee pain in young athletes. It causes swelling, pain and tenderness just below the knee, over the shin bone (also called the tibia). Osgood-Schlatter commonly affects boys who are having a growth spurt during their pre-teen or teenage years. One or both knees may be affected.
