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). Instead, OCD is a problem of the bone underlying the cartilage, which may secondarily affect the articular cartilage. When possible, non-operative forms of management such as protected reduced or non-weight bearing and immobilization are used. Try our Symptom Checker Got any other symptoms? Cahill BR.
