The knee joint prosthesis consists of a tibial plateau (1) that can be anchored in the tibia and a femoral part (4) fastened in the femur; both parts (1, 4) are preferably made of metal. An intermediate part (3) made of plastic is arranged between the two, on which the femoral part (4) moves in a sliding manner when the joint is flexed and stretched. In order to reduce the abrasion of the plastic, support bodies (8) made of hard material, preferably of the material of the femur part (4), are distributed in the bearing surface (6) of the intermediate part (3) for the femur part (4), the support or Sliding surfaces (10) are integrated in the bearing surface (6) and are adapted to their shape. <IMAGE> |
