System and method for joint resurface repair
First Claim
1. A method of mapping a surface contour of an articular surface comprising:
- establishing a working axis extending from said articular surface;
providing a first probe having a first diameter;
measuring a first distance between at least a first point of said articular surface and a first plane substantially normal to said working axis at a distance substantially equal to said first diameter of said first probe from said working axis;
providing a second probe having a second diameter; and
measuring a second distance between at least a second point of said articular surface and a second plane substantially normal to said working axis at a distance substantially equal to said second diameter of said second probe from said working axis.

Abstract
An implant for installation into a portion of an articular surface includes a protrusion configured to cover an un-excised portion of articular surface proximate to the implant. 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 may also include indentations such as grooves to promote articular cartilage remodeling over a portion of the load bearing surface of the implant. An elongated or non-round implant is also provided having two opposing concentric arcuate shaped sides, 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.
