Patent ID: 8147497

Claim:
A patella clamp mechanism, comprising: a) a tool guide comprising opposed first and second jaws connected to each other at a proximal guide junction and being adapted to releaseably hold a patella, wherein the first and second jaws comprise aligned and opposed first and second miter slots; and b) a femur engaging component extending from an outer surface of the first jaw opposite the first miter slot, wherein the femur engaging component comprises a link portion extending along a longitudinal axis from a proximal link end secured to the outer surface of the first jaw opposite the first miter slot to a distal hook end with an imaginary extension of the link portion along the longitudinal axis extending through the first miter slot of the first jaw, c) wherein the distal hook end of the femur engaging component is detachably connectable to a reference feature on a femur to enable a patella to be held in the clamp mechanism at an appropriate orientation relative to the femur to enable resection of the patella along a resection plane defined by the first and second miter slots.
