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 atleast one of the posterior, anterior, and distal surfaces of the condyles of afemur to provide a surface for receiving a femoral prosthesis (5). Theapparatus (30) includes a measuring system to determine a location of theposterior, anterior, and distal resections to be made. The apparatus (30)additionally includes a graduated scale (80) to measure a distance between theanterior and posterior surfaces of the femoral condyles, including markings(82) representing different prosthesis sizes, markings in between the sizemarkings to account for the difference between the measured distance, and thenearest prosthesis size. The femoral resection apparatus (30) and method maybe used with a tibial resection apparatus (400), and method for resecting atibial plateau to provide a surface for receiving a tibial prosthesis. Thetibial apparatus includes a scale to indicate a proper resection location.Additionally, a patellar reamer apparatus (516), and method may be used to fita patella with a patellar insert (504).
