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.
给出了正常情况下和存在发育异常畸形时髌股关节工作的数学建模结果。已确定,膝关节从外观和功能上构成一个典型的凸轮机构。阐述了股骨髁与髌骨之间相互作用的生物力学方案。根据凸轮机构方案进行了实验性X线测量研究。根据所进行的统计分析,在髌股关节发育异常的情况下,膝关节会发生变化,这可能导致其卡顿;髌骨在膝关节中的位置取决于股骨髁解剖结构的特点。
