Abstract

A method of resecting distal and anterior portions of a distal portion of a femur for a bicompartmental prosthesis is provided. The method includes generating a geometric representation of the distal portion of the femur. A virtual anterior resection plane is calculated at a predetermined depth and is oriented at a predetermined angle relative to the femur. The method identifies a distal-most point of a lateral portion of the virtual anterior resection plane and an AP line. A varus/ valgus angle and an anterior-posterior distance are calculated. Anterior and distal resection guides are navigated according to the parameters calculated from the method.
