Tibial Resurfacing System and Method

An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone, said implant resection system comprising:

• a guide configured to be coupled generally perpendicular to said first bone proximate to said defect, said guide comprising a body portion defining a plurality of excision passageways, said excision passageways each defining a generally cylindrical core pathway configured to extend generally perpendicular to said first bone which partially overlaps with an adjacent generally cylindrical core pathway, wherein a projection associated with each of said plurality of said generally cylindrical core pathways defines a truncated cylindrical excision site extending through a portion of said articular surface, and wherein each truncated cylindrical excision site partially overlaps with at least one adjacent truncated cylindrical excision site.
