Abstract
An implantable prosthetic component, such as a femoral stem, includes a plurality of bone-engaging ribs which are configured so as to engage dense cancellous bone upon implantation. The ribs have a geometry and spacing for achieving optimal fixation in the medullary canal of the femur by engaging predetermined dense cancellous bone.
