Embodiments of the present application relate generally to provisional orthopedic components, and specifically, to a trial system including a cam module (10) and a trial femoral component (100) that can be used during joint replacement surgery. The systems and methods described help a surgeon prepare a patient's bone to receive a permanent implant by providing a system that can be used to guide preparatory box cuts, and that can then be completed with a cam module (10)—without removal from the patient's bone—so that the same component can be used for the trialing process.
