SYSTEM AND METHOD FOR JOINT RESURFACE REPAIR

摘要

An implant (40) for installation into a portion of an articular surface (50) includes a protrusion (45) configured to cover and un-excised portion of articular surface proximate to the implant (40). Another implant may form a cavity to allow the un-excised portion of articular surface to remodel over a perimeter edge of the implant. The implant (40) may also includes indentatio ns (6805) such as grooves (6807) to promote articular cartilage remodeling over a portion of the load bearing surface of the implant (40). An elongated or non - round implant (6600) is also provided having two opposing concentric arcuate shaped sides (6611, 6612), as well as a method to seat such an implant in an articular surface. A method for seating an implant without cutting articular cartilage is also provided.
