ABSTRACT:
A joint prosthesis component system allows an inferior component of a prosthesis system to be offset from a superior component of the system. In one embodiment the joint prothesis component system comprises a tibial tray having an offset tibial stem. An adapter element connects between the tibial tray and tibial stem to provide the desired degree of offset and the orientation of the offset. The adapter element is constructed such that a longitudinal axis extending through a first end thereof is offset from a longitudinal axis extending through a second end thereof.
