To solve the tribological problems of existing knee prostheses, the application of new materials and geometric designs for improvement of lubricating film formation are necessary. For this purpose, the applications of artificial articular cartilage and duo-radius knee prostheses are proposed. The tribological behavior of knee prostheses with a silicone rubber layer was examined for different viscosity and motion conditions. Duo-radius femoral components were tested for three tibial components with silicone rubber. The tribological severity was evaluated in terms of frictional torque and degree of separation using the electric resistance method in a knee joint simulator. As a result, the importance of swing phase of walking pattern was shown and duo-radius knee prostheses showed better frictional behavior than cylindrical one for low-viscosity lubricant.
