Given is a knee-joint endoprosthesis that displays a femur part with convexly-curved condylar cups, and a tibia part with a tibia plateau insert displaying correspondingly, concavely-curved tip surfaces. A connecting part projects with one end into an intermediate space between the condylar cups, is pivotably connected there with the femur part by means of a transverse bolt, and at the other end has a pin that is rotatably journaled in a boring passing through the tibia plateau. To realize, in the case of this axle knee, a bending movement with additional rolling movement components, the pin of the connecting part is journaled in impact-free, axially-displaceable fashion, and the condylar cups approximate a rotation surface about a condylar cup axis that runs above and parallel to the axis of the transverse bolt.
