An axial height adjustable, revision cutting in the shape of a final distal femur implant component. The revision guide includes a rod adapted for intimate contact within an intramedullary canal of a femur, and includes a threaded passageway. The revision cutting guide is adapted for removable attachment to a distal portion of the femur. A vernier-bolt is rotatably positioned through the shaped body of the revision cutting guide so as to be adjustably received within the threaded passageway thereby providing for movement of the shaped body of the revision cutting guide relative to the distal portion of the femur.
