Abstract
An artificial joint as an endoprosthesis for a human joint, including a first joint part having two first functional surfaces, a second joint part having two second functional surfaces, the two first and second functional surfaces of each joint part being convex-concave, concave-convex, or convex-convex in a proximal-distal direction, a projection associated with the first joint part; and a recess associated with the second joint part. The recess is configured to engage with the projection so as to determine a relative position of the first and second joint parts in a transverse plane of the joint and to form a stop for a sliding movement of the first and second joint parts relative to each other. The two first functional surfaces are pivotable about a pivot axis with respect to the second functional surfaces.
