Osgood-Schlatter Disease

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


This condition is most commonly experienced in children and teens who are going through a growth spurt and are physically active. It is not usually found in children over the age of 16. Children who have this condition typically grow out of it and can expect full recovery.

While many cases of Osgood-Schlatter disease occur due to a growth spurt, young athletes who perform repetitive kicking, jumping or running can also develop it. Overuse causes repeated strain on the attachment of the patellar ligament to the growing tibia and, in some cases, small flakes of bone can be pulled from the tibia, causing a hard bony bump to develop as a result.
