An implant for mounting on a resected articulation surface of a bone includes a tray (36) having a top surface (42) and an opposing bone apposition surface (44). An opening (62) extends completely through the tray between the top surface and the bone apposition surface. A bearing member (32) is mounted on the top surface of the tray, the bearing member having a top articular surface (82). An anchor (34) downwardly projects away from the bone apposition surface of the tray, the anchor being adapted to engage the bone and being configured so that the anchor can selectively pass completely through the opening of the tray. A fastener (40) connects the anchor to the tray.
