Implantable prosthesis for replacement of the human knee joint

Abstract

An implantable prosthesis for replacement of a human knee joint, including a joint device with a joint head and a joint base interacting with the joint head, which are provided for selectively realizing at least one joint movement in the form of a bending and/or extension movement. The joint head has two first sliding surfaces which are arranged at opposite axial ends of the joint head and are spatially separated from each other by a central joint head section. The joint base has two second sliding surfaces which are formed axially opposite each other on laterally arranged joint elements of the joint base and are in sliding engagement with the respective first sliding surfaces of the joint head. The two first sliding surfaces and the two second sliding surfaces are formed to realize at least one bending and/or extension movement, and wherein the central joint head section has at least one guide channel for passing a tool, a distraction intramedullary nail or a femoral or tibial shaft anchor.
