摘要:
A cartilage resurfacing implant (10) is provided for replacing cartilage of an articulating portion of a bone at a skeletal joint having opposed joint surfaces. The cartilage resurfacing implant includes a body (12) having a bearing surface (14) and a bone interface (16). The bearing surface is able to support articulation with an opposing joint surface.

A milling system for use in resecting at least a portion of a joint articulation surface of a bone includes an alignment guide having a top surface and an opposing bottom surface with an opening extending therebetween. Fasteners are used to secure the alignment guide to the bone so that the alignment guide is suspended above the bone. A template is removably mounted to the alignment guide so that a plurality of guide paths extending through the template are aligned with the opening in the alignment guide. A mill extends down through the guide path and has a burr on the end thereof for resecting the bone.

A trochlear groove implant includes a body having a an articular surface and an opposing bone apposition surface, the articular surface and the bone apposition surface each extending between a proximal end and an opposing distal end of the body. An elongated channel is recessed on the articular surface and longitudinally extends between the opposing ends of the body. An elongated ridge outwardly projects from the bone apposition surface and longitudinally extends between the opposing ends of the body.

摘要:
A milling system for use in resecting at least a portion of a joint articulation surface of a bone that includes a template (38) having a base (42) with a top surface, an opposing bottom surface, and an opening (58) extending therebetween. One or more fasteners are used to removably mount the template on a bone. A guide (40) is movably mounted on the template and projects across at least a portion of the opening of the template. The guide is selectively movable across at least a portion of the opening of the template. A rotatable mill (166) is mounted on the guide. The mill is selectively movable along at least a portion of the length of the guide.
