1. A system for preparing a femur for receiving a prosthesis, the system comprising:
a femoral template including a body having a locating bore; and
a plurality of femoral offset coin assemblies including a plurality of femoral coin housings and a corresponding plurality of positioning coins, wherein each of the plurality of positioning coins is rotatably coupled to one of the corresponding plurality of femoral coin housings, wherein each of the femoral offset coin assemblies can be selectively secured within the locating bore to determine a desired femoral offset, each positioning coin having a bore offset a distance relative to a longitudinal center of the positioning coin; and
a locating stem operatively coupled to the bore;
wherein the positioning coin is rotatable within the locating bore, causing the femoral template to move around a distal femur when the locating stem is positioned within the femur, wherein the positioning coin can be rotated within the locating bore until a position is attained in which the body achieves desired coverage over cortical bone of the distal femur.
