Abstract
A method for replacing a joint surface, which includes resecting a first portion of the joint surface to create a wall surface and inner resected surface. The wall surface (2006) separates the inner resected surface and a non-resected portion of the joint surface. Further included in the method is cutting a concave groove having a first radius into the wall surface, and engaging the concave groove with a periphery of a joint prosthesis. The periphery includes a second radius that is substantially the same as the first radius of the concave groove.
