ABSTRACT:
A posterior stabilized femoral trial apparatus for preparing a patient's femur to receive a posterior stabilized femoral prosthesis includes a trial body with proximal and distal portions, the distal portion having an articulating surface for articulating with a patient's tibial component. A module fits the trial body at the proximal surface, the module being selected from a kit or group of modules of differing sizes and shapes. The module includes a rasping surface that extends longitudinally. The trial body includes cutting surfaces at the posterior condyles. The module is removably attachable to the trial body at the proximal surface. During use, the apparatus of the present invention enables the surgeon to resect the patient's femur in a revision surgical case using the trial itself and more particularly the rasping surface and cutting surface thereon.
