股骨胫骨髌骨三体人膝关节咬合运动数学模型

A Human Knee Articulate Mathematical Model on Femur Tibia Patella 3 Segmetents

基于人膝关节的解剖特征，在文献［３］的基础上，引入了股骨髌骨关节，从而建立了一个完整的人膝关节在矢状面内运动的咬合数学模型。该模型包含了运动膝关节股骨与胫骨间及股骨与髌骨间的咬合滚动和咬合滑动。

In this paper, based on the previous work of S. Turgut Tumer et al, a human knee articulate mathematical model on femur bibia patella 3 segments is established by introducing patella femur joint. This model includes both rolling and sliping motions of femur tibia joint and femur patella joint. It can be employed in simulating the biodynamic response of human lower extremity.
