ABSTRACT:
A femoral component for a hip prosthesis includes a stem with a porous surface or the like to enhance bone fixation. The porous surface is applied to the stem in a predetermined manner to accommodate stress lines for the stem and generate a curvilinear inferior boundary for the porous surface. A method of construction utilizes the stress lines to approximate a boundary for the porous surface.
