Abstract: A tibial insert and baseplate system is disclosed for a prosthesis. The tibial baseplate is right or left knee specific while the insert is symmetrical about an anterior-posterior centerline and is thus not right or left knee specific. The baseplate has an outer periphery which is asymmetrical to mate exactly with either the left or right tibia but not with both. The upper surface of the baseplate, which also has an asymmetrical periphery, in addition, defines a symmetrical housing within the periphery for the symmetrical insert.
