[Features of adaptive changes in the knee joints of fencers exposed to specialized loads]

Sportsman-fencers (683 persons) of various qualification and types of fencing (sabre fencers, foil fencers, swordsmen) have been roentgenologically examined. Of them 97 have been examined for the second time in a year. For a comparison 204 persons nonsportsmen have been examined. Increased specialized loadings of chop-push character, peculiar for fencing, accelerate processes of bone sinostosis and result in certain morphological changes in the components of the knee joint: the joint cartilage becomes thinner (as demonstrates the roentgenologically measured joint cleft), periostal osteogenesis on the surface of epiphyses, endothelial osteogenesis in the bone diaphyses become activated.
