Abstract

A cutting apparatus for resecting a distal face of a femur prior to implanting a femoral component of a total knee prosthesis, comprises an elongate rod adapted for inserting into an intramedullary canal of the femur, a distal femoral cutting block, and a distal femoral jig assembly. The jig assembly can position the distal femoral cutting block on either left leg or right leg. It includes a distal femoral jig having at least one passage for slidingly receiving the rod with a preset valgus angle and a distal end face being adapted for abutting against on the distal face of the femur of either left leg or right leg dependent on its two flip orientations.
