    Abstract

    The object of this study is to introduce contact points' trajectories on the articulating surfaces and kinematics of knee prosthesis under various walking conditions for various types of prosthesis to help to design new prosthesis. Since in vivo measurement of knee prosthetic articulation is almost impossible, we created a 3D mathematical model consisted of the tibio-femoral and patello femoral compartments of artificial knee joint. As the model could reproduce the comprehensive and sophisticated motion of a knee prosthesis, it is possible to generate and analyze various walking conditions with various types of knee prostheses and hence reproduce joint rotation mismatch, excessive deviation of contact points and a loft off between the medio and lateral sides of the joint.
