ABSTRACT:
A provisional component for use with differently sized first and second prosthetic orthopedic components. The provisional component has a configuration which is substantially similar to the first prosthetic component and has a predefined correspondence to the second prosthetic component. The provisional component is mounted on a bone to assess the fit of the first prosthetic component. The provisional component includes a referencing element for defining a reference point on the bone if the fit of the provisional component indicates that the second prosthetic component should be used. An instrument guide is aligned with the reference point and used to properly position a surgical instrument to prepare the bone to receive the second prosthetic component. The provisional and prosthetic components may all be femoral components which have an articulating surface defining a single condylar-shaped projection.
