1. A trochlear groove implant comprising:
- a body having a first side with an articular surface and an opposing second side with a bone apposition surface, the articular surface and the bone apposition surface each extending between a proximal end and an opposing distal end of the body;
an elongated channel recessed on the first side of the body and longitudinally extending between the proximal end and the opposing distal end of the body, at least a portion of the articular surface having a substantially smooth convex curvature extending between the proximal end and the distal end of the body; and
an elongated ridge outwardly projecting on the second side of the body and longitudinally extending between the proximal end and the opposing distal end of the body, at least a portion of the bone apposition surface having a substantially smooth concave curvature extending between the proximal end and the distal end of the body.

Abstract
A trochlear groove implant includes a body having a first side with an articular surface and an opposing second sid with a bone apposition surface, the articular surface and the bone apposition surface each extending between a proximal end and an opposing distal end of the body. An elongated channel is recessed on the articular surface and longitudinally extends between the opposing ends of the body. An elongated ridge outwardly projects from the bone apposition surface and longitudinally extends between the opposing ends of the body.

25. A rasp comprising:
-
an elongated handle having a top surface and an opposing bottom surface that each extend between a first end and an opposing second end; and
a cutting mount positioned at the second end of the handle and comprising a plurality of teeth forming a cutting surface, at least a portion of the cutting surface projecting below the bottom surface of the handle and having a substantially constant convex surface of rotation that extends between a first end and an opposing second end, the surface of rotation having a central ridge extending between the opposing ends. - View Dependent Claims (26, 27, 28)
