Abstract: Two hundred subjects were randomly selected to record their basic information, joint angle and sliding speed, and 181 valid data were analyzed. According to a volunteer′s MR, CT data, a 3D cartilage and bone model of the knee 140° was established. According to the result of kinematic analysis and knee anatomy structure, the load and constraints were defined. The stress concentration position on the knee cartilage was obtained in the Abaqus6.14. The results showed that the slider with large weight or sliding too fast should increase the turning radius in order to reduce the stress of the centripetal force on knee joint cartilage. It is advisable to control the speed of plough type turn within 3m/s.

Key words: knee joint cartilage, finite element analysis, plough type ski, turning side of knee joint, biomechanics
