A method for preparing a femur for receiving a prosthesis. The method includes the following: fixing a femoral trial component to the femur； coupling a reamer bushing relative to the femoral trial component； reaming a cavity into the femur using the reamer bushing as a guide； coupling at least one of a modular femoral box trial and a stem adapter relative to the femoral trial component； trialing the femoral trial component with the articulating surface of the femoral trial component； and performing the coupling of the reamer bushing, the reaming of the cavity, the coupling of the at least one of the modular femoral box trial and stem adapter, and the trialing of the femoral trial component all while the femoral trial component remains fixed to the distal femur.
