[A human knee articulate mathematical model on femur-tibia-patella 3-segmetents].

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