Abstract
The invention is directed to an orthopaedic implant for implantation into a bone at a joint. The orthopaedic implant 10 includes an articulating surface 20 for mating with a complementary implant 30. The orthopaedic implant includes a body 12 defining the articulating surface. The articulating surface 20 includes a conforming surface 22 bounded by a translational surface 24. The conforming surface 22 allows rotational movement between the articulating surface and the complementary implant, and the translational surface 24 allows rolling and translational movement between the articulating surface and the complementary implant. The conforming surface 22 is tangent at a periphery thereof to the translational surface 24.
