Abstract

The focus of this study is to simulate the kinematic and dynamic behaviors of a two dimensional tibiofemoral joint with a quasi-static and a dynamic model. Parameters of interest include the joint surface contact point, ligament forces, and slide/roll ratio between the femur and tibia. Model results are compared to experimental cadaver studies available in literature. Furthermore, the effect of femur surface geometry on the above mentioned characteristics is also deter- mined. The pattern of ligament forces from the analytical study matches well qualitatively with the experimental study. Change of femur surface geometry has little effect on the pattern of slide/roll ratio. 1 Introduction Knee is the largest and most complicated joint in a human body. Statist
