Abstract

A tibia member of a knee joint endoprosthesis used as a replacement for a resectioned tibia head. The tibia member includes a bridge element having a shank anchored in the tibia and provided with a shackle or flap secured thereto at the front side thereof. An outer and concave pan member is provided at the lower extremity of the flap, the pan member having rounded-off edges for reception of tendon extremities. A convex clamping element is connected to the bridge element at the lower extremity of the flap for pressing the tendon extremities into the concave pan member, so that no sharp edges are thereby placed in contact with the tendon.
