METHOD AND APPARATUS FOR LOCATING RESECTION AT THE DISTAL CONDYLAR FEMUR, TIBIA, AND PATELLA

摘要

A femoral resection apparatus (30) and method are provided for resecting at least one of the posterior, anterior, and distal surfaces of the condyles of a femur to provide a surface for receiving a femoral prosthesis (5). The apparatus (30) includes a measuring system to determine a location of the posterior, anterior, and distal resections to be made. The apparatus (30) additionally includes a graduated scale (80) to measure a distance between the anterior and posterior surfaces of the femoral condyles, including markings (82) representing different prosthesis sizes, markings in between the size markings to account for the difference between the measured distance, and the nearest prosthesis size. The femoral resection apparatus (30) and method may be used with a tibial resection apparatus (400), and method for resecting a tibial plateau to provide a surface for receiving a tibial prosthesis. The tibial apparatus includes a scale to indicate a proper resection location. Additionally, a patellar reamer apparatus (516), and method may be used to fit a patella with a patellar insert (504).
