Abstract
The metal anchoring part, in one embodiment, has a flat bearing surface to receive a synthetic tibial endoprosthesis part as well as a parallel tibial plateau from which anchoring rails project. The anchoring rails are slidably mounted within guide bores in a tibia to permit sliding of the anchoring part in the ventral/dorsal direction. In addition, a lock-like latch is provided in each rail to permit securement of the anchoring part in a tibia after placement. The anchoring part may be made as a half part for mounting on the medial or lateral part of a tibia or as a full part. A rotatable bolt may also be mounted in a pair of aligned rails to expand expandable rings secured to the tibial plateau for securing the part to the spongiosa of the tibia.
