Glenoid resurfacing system and method

A system for repairing a defect on a portion of an articular surface of a patient's glenoid, said system comprising:

• an excision device including:
• a shaft configured to be advanced along a working axis, and
• at least one cutter configured to form a generally hemispherical excision site in said glenoid about said working axis, wherein said at least one cutter has a cross-sectional thickness of 0.5 mm to 3.0 mm and said at least one cutter includes a cutting surface having a generally arcuate shape sweeping towards a proximal end of said shaft;
• and
• an implant including a load bearing surface and a bone facing surface, wherein said load bearing surface exhibits a contour substantially corresponding to the contour of the articular surface and said generally hemi-spherical bone facing surface is configured to be received in said generally hemispherical excision site.
