The present invention provides an improved prosthetic stem for implantation in a bone. Specifically, the present invention provides a prosthetic femoral stem having a strengthening rib protruding from the substrate thereof and being flush with a porous coating formed thereon. The strengthening, rib is advantageously positioned so as to increase the cross-sectional moment of inertia of the prosthetic femoral stem and thereby decrease the stress on the anterio-lateral surface of the femoral stem. A protrusion in accordance with the present invention may also be utilized with a prosthetic femoral stem absent a porous coating. In such an embodiment, the height of the protrusion is such that the protrusion will be surrounded by the cement mantle formed when the prosthetic femoral component is cemented in a femoral canal.
