title: Osteochondritis dissecans of the knee.
abstract: A case of osteochondritis dissecans of the knee is described in which the site of the lesion, on the supero-medial aspect of the lateral femoral condyle, is unique. This case supports the theory that direct recurrent minor trauma causes osteochondral fractures which remain ununited producing the characteristic lesion.
