Case Discussion

Osteochondral defects are focal areas of articular damage with cartilage damage and injury of the adjacent subchondral bone.

MRI is the modality of choice, with high sensitivity and specificity for the detection of separation of the osteochondral fragment

Osteochondral injuries are staged from I - V.   The displaced osteochondral fragment makes this a stage IV injury,
