The exact cause of osteochondritis dissecans is unknown. It may be caused by a reduction of blood flow to the end of the affected bone. This may occur from repetitive trauma — small, multiple episodes of minor unrecognized injury that damage the end of the affected bone. There may also be a genetic component involved, making some people more inclined to develop the disorder.
