A set of instruments for preparing a femur and tibia for receipt of a partial knee prosthesis can include a femoral drill guide that is selectively connected to an intramedullary (IM) rod. At least one sizing spoon can communicate with the femoral drill guide. The femoral drill guide can have terminal cutting surfaces. A tibial cut guide can be selectively connected to the femoral drill guide. A dial member can be disposed on one of the femoral or tibial cut guides that when rotated moves at least one of the spoons in a superior/inferior direction.
