ANATOMICALLY GUIDED INSTRUMENTATION FOR TROCHLEAR GROOVE REPLACEMENT

摘要

A method for replacing a joint surface, which includes resecting a first portion (2004) of the joint surface to create a wall surface (2006) and inner resected surface (2007). The wall surface (2006) separates the inner resected surface (2007) and a non-resected portion of the joint surface. Further included in the method is cutting a concave groove (2008) having a first radius into the wall surface (2006), and engaging the concave groove (2008) with a periphery (2102) of a joint prosthesis (2100). The periphery (2102) includes a second radius that is substantially the same as the first radius of the concave groove (2008).
