Method and apparatus for preparing a seating surface of prescribed depth, contour configuration and area delineated by a prescribed peripheral boundary extending along the bone of a natural joint at which a prosthetic device is to be implanted includes positioning a guide on the bone, the guide having a guide slot following a path geometrically similar to the peripheral boundary of the seating surface, inserting a cutting device altitudinally through the guide slot at any selected location along the path of the guide slot, and translating the cutting device along the guide slot to cut an outline groove in the bone coincident with the peripheral boundary of the seating surface. The guide then is removed from the bone, and portions of the bone lying within the area delineated by the outline groove are removed to establish the seating surface.
