Abstract
Five cases of so-called tangential osteochondral fracture of the knee joint, of which the fracture lines were tangential to joint surface of the femoral condyle, were presented. This type of fracture is frequently overlooked and become easily to be chronic.
While the majority of reported cases were caused by sport, four of our 5 cases were caused by severe traumas except one.
Two fresh cases were treated by open reduction and the other three by extirpation of the fragment with excellent or satisfactory results.
