Abstract
The invention relates to a knee-joint endoprosthesis with a femoral part anchored in the femur and a tibial plate connected to the tibia bone, on which tibial plate tibial parts are arranged by way of gliding surfaces, and preferably with meniscus elements disposed between the femoral part and the tibial parts. With a view to mechanically stable anchorage of the tibial part on the tibial plate that may optionally be subsequently released, even at the implanted joint, so that the tibial part can be exchanged, it is proposed that the tibial part or parts are detachably connected to the tibial plate by wedging, screwing and/or bracing.
