First Claim
Patent Images
1. An implant for replacing a portion of an articular surface comprising:
- a load bearing surface having a contour defined by a first curve string based on a contour of said articular surface in a first plane and a second curve string based on a contour of said articular surface in a second plane, said first and second planes being intersecting; and
a bone contacting surface.

Abstract
An implant for replacing a portion of an articular surface including a load bearing surface and a bone contacting region. The load bearing surface had a contour defined by a first curve string which is based on a contour of the articular surface being replaced in a first plane. The load bearing surface of the implant is further defined by the contour of the articular surface being replaced in a second plane, in which the first and second planes are mutually intersection planes.
