Abstract
A distal femur resecting apparatus for use in the preparation of a human distal femur for the implantation of a human femoral prosthesis. The resecting apparatus includes a positioning apparatus and a pattern device. The positioning apparatus includes a positioning block for attachment to a femur, an adjustment block having an intermedullary rod extending into the femur, and a rotational alignment device for attachment of the pattern device to the positioning apparatus. The pattern device comprises an individual or pair of mediolaterally located plates having a cutting path described therethrough similar in shape to the interior profile of a human femoral prosthesis. The cutting path guides a reciprocating, oscillating, or rotating cutting tool along a path for removing material from some or all of the distal femur to shape the distal femur to accept a distal femoral prosthesis.
