Case Discussion

Osteochondritis dissecans is caracterized by separation of an osteochondral fragment from the articular surface. An osteochondral fragment may be present in situ, incompletely detached, or completely detached. Occurs only on convex surfaces of the bone such as the medial condyle of the femur, capitellum, proximal surface of the talus, head of the first metatarsal. Trauma is the primary insult, and ischemia a secondary injury.
