title: [Modelling of the knee joint loading conditions in the view of mechanics].
abstract: The results of mathematic modelling of work of femoropatellar joint in normal conditions and in the presence of dysplastic deformity were adduced. There was established, that a knee joint (KJ) by its external appearance and function constitutes a classic cam mechanism. Biomechanical scheme of interaction between the femoral bone processus and patella was elaborated. In accordance to scheme of cam mechanism its experimental roentgenometric investigations were performed. According to statistical analysis performed, in conditions of dysplasia in femoropatellar joint the changes in the KJ occur, which may cause its blockade; the patella position in the KJ depends on peculiarities of anatomical structure of the femoral bone processuses.
