Osgood Schlatter disease

Osgood-Schlatter disease An inflammation of the patellar tendon and surrounding soft tissues at the point where the tendon attaches to the tibia in children. Osgood-Schlatter disease is caused by repetitive stress or tension on a part of the growth area of the upper tibia (the apophysis). The disease may also be associated with an avulsion injury, in which the tendon is stretched so much that it tears away from the tibia and takes a fragment of bone with it. Osgood-Schlatter disease most commonly affects active young people, particularly boys between the ages of 10 and 15, who play games or sports that include frequent running and jumping. Treatment includes rest, casting if necessary, and rarely surgery. See also osteochondrosis.
