Abstract
A provisional orthopedic prosthesis having a first provisional component and an optional second component. The provisional prosthesis may be a partial knee prosthesis and is used to assess the fit of a permanent prosthesis having first and second components. The first provisional component has a size which differs from the first permanent component and is mountable on a bone which has been only partially prepared to receive the first permanent component. Providing a provisional component which is mounted on a partially prepared bone, simplifies the preparation of the bone for a differently sized component if the provisional indicates that the preliminarily selected permanent component is incorrectly sized.
