ABSTRACT:
When the knee bends, the condyle-like bearing surfaces of the femur part of the prosthesis slide on the tibia-like rolling surfaces of the tibia part. The motion is guided by a web of the tibia part which engages in a fork-like mounting of the femur part. The web has a head which has a cylindrical shape to slide on a corresponding cylindrical section formed by a member mounted in the femur part. Web and mounting are preferably made of metal whereas the member in the femur part is made of another material, preferably, a moulded plastics member.
