Experimental sports injuries of cartilage and bone were produced by applyihng cyclic shear force (sin wave, 1Hz) to the articular surface of pig knee joint (young and adult). Bone-cartilage damage was evaluated according to the crack and abrasion of the articular surface and the fracture of the subchondral cancellous bone. The cyclic shear loading was more destructive to the articular end then the cyclic compression loading. The first site of failure was different by maturity. 'Closed' lesions at the subchondral plate in the young predict the precursor of osteochondritis dissecans. 'Open' lesions to the deeper layers from the articular surface in the adult have the characteristic of osteoarthritis. It was suggested that experimentally produced destruction models were reflected the injury patterns which were seen in sports players.
