Osteochondritis dissecans of the capitellum: Arthroscopic-assisted treatment of large, full-thickness defects in young patients.

Abstract

Methods of treatment for mild juvenile osteochondritis dissecans (OCD) of the capitellum include activity modification and periods of immobilization, followed by therapy and range of motion exercises. Surgical treatment may be indicated if there are persistent symptoms, a loose body, the child is approaching skeletal maturity, or if magnetic resonance imaging reveals a fracture through the articular cartilage. We describe a technique of arthrotomy, using an arthroscope as a visual aid, for the treatment of large, full-thickness OCD lesions of the capitellum in young patients. The arthroscopic camera allows the surgeon to view difficult-to-see areas, and photographs can be taken throughout the procedure for documentation.
