Femoral stem attachment for a modular knee prosthesis

摘要

The present invention provides a knee prosthesis having a femoral component having a pair of spaced apart condylar portions and a boss structure extending between the condylar portions. The boss structure has a top surface that extends generally horizontally in a transverse plane and an opposed inferior surface. The knee prosthesis also includes a stem component having a proximal end and a distal end. The knee prosthesis further includes an attachment nut for securing the stem member to the femoral component. <IMAGE>
