Abstract:
1. A method for preparing a femur for receiving a prosthesis, the method comprising: positioning an intramedullary (IM) member in the femur; positioning a femoral trial component onto a distal end of the femur, the femoral trial component having an attachment portion, an articulating surface and at least two cut guide surfaces thereon; attaching a modular boss assembly to the attachment portion of the femoral trial component, the modular boss assembly having a boss stem that is configured to operably connect to the IM member; confirming a desired contact between the femoral trial component and the distal femur is attained based on the attaching; fixing the femoral trial component to the distal femur based on the confirming; removing the modular boss assembly from the femoral trial component; coupling a reamer bushing relative to the femoral trial component; reaming a cavity into the femur using the reamer bushing as a guide; and coupling at least one of a modular femoral box trial and a stem adapter relative to the femoral trial component; and wherein removing the modular boss assembly, coupling the reamer bushing, reaming the cavity and coupling at least one of the modular femoral box trial and stem adapter are all performed while the femoral trial component remains fixed to the distal femur.
