Abstract:
1. A multi-piece knee resection instrument for resecting the distal femur comprising: a first resection guide block for attachment to the medial or lateral side of the distal femur having a first planar surface lying in a first plane facing generally anteriorly and a second planar surface extending distally from said first planar surface along a second plane at an obtuse angle to the first plan, said first and second planar surfaces each having a coupling element thereon and a planar third surface extending from the second planar surface at an obtuse angle to the second surface, and extending in a third plane generally perpendicular to the first plane and generally parallel to a resected distal planar surface of the femur; a first resection guide having a coupling element for releasably mounting the first resection guide to both of the coupling elements on said first and second surfaces of said first resection guide block, said first resection guide having a cutting tool engaging surface thereon for directing a cutting tool in a direction generally parallel to the first and second planes; and a second resection guide releasably mounted on the planar third surface of said first resection guide block and extending along a medial-lateral plane across at least part of the distal planar surface of the femur, said second resection guide having two non-parallel cutting tool engaging planar surfaces thereon extending transverse to the third plane and extending through the distal planar surface of the femur with one of the two non-parallel cutting tool engaging planar surfaces extending along a plane at an obtuse angle to the third plane.
