Osteochondritis dissecans.

Abstract

Osteochondritis dissecans (OCD) is a pathological process affecting the subchondral bone (most often in the knee joint) of children and adolescents with open growth plates (juvenile OCD) and young adults with closed growth plates (adult OCD). It may lead to secondary effects on joint cartilage, such as pain, oedema, possible formation of free bodies and mechanical symptoms, including joint locking. OCD may lead to degenerative changes if left untreated. [1]
