Attorney, Agent or FirmInternational ClassA61B 017/58AbstractA femoral resection apparatus and method is provided for resecting at least one of the posterior, anterior, and distal surfaces of the medial and lateral condyles of a femur to provide seating surface to receive a femoral prosthesis. The apparatus includes a measuring system to determine a location of the posterior, anterior, and distal resections to be made. The apparatus additionally includes a graduated scale to measure a distance between the anterior and posterior surfaces of the femoral condyles, including markings representing different prosthesis sizes and markings in between the size markings to account for the difference between the measured distance and the nearest prosthesis size. The femoral resection apparatus and method may be used in combination with a tibial resection apparatus and method for resecting a tibial plateau to provide a seating surface to receive a corresponding tibial prosthesis. The tibial apparatus includes a measurement scale to indicate a proper resection location. Additionally, a patellar reamer apparatus and method may be used to fit a patella with a patellar insert. The patellar reamer apparatus also includes a measurement scales to indicate a proper reaming depth which corresponds to a thickness of the patellar insert. | |
