Abstract
A femoral guide is shown in the form of a femoral sizing guide for determining the size of a femoral knee prosthesis to be implanted at an implant site at a distal femur and includes a femoral sizing block connected to a foot component for selective pivotal movement about a pivotal axis extending in a generally axial direction and essentially intersecting the transepicondylar axis of the distal femur to enable a guide arrangement on the femoral sizing block to be located for facilitating subsequent placement of a femoral cutting guide on a distal femur in position to rotationally locate an anterior cut in a plane anterior of and essentially parallel to the transepicondylar axis of the distal femur. The femoral sizing block is connected to the foot component for selective linear movement to compensate for size variations outside standard femoral knee prosthesis sizes. Visible indications are provided of the location of a subsequently implanted femoral knee prosthesis. A corresponding method determines the appropriate location and position of the femoral knee prosthesis to be implanted at the implant site, and the size of the femoral knee prosthesis.
