Abstract
The tibial implant is made with two truncoconical faces which extend from a common plane for different distances. The differential extent permits implantation in a natural tibia having sockets which have different degrees of wear, thus avoiding unnecessary loss of healthy bone during a resection procedure. The truncoconical faces are provided on metal bowls which can be welded together along a common plane and which together form a support to receive a plastic member providing the joint sliding surfaces and providing a pair of expansion elements for expanding barbed hollow bodies extending from the metal bowls.
