A femoral stem for canines or humans is made bone-compliant by use of a thick sintered titanium body in a proximal bone contacting region and a polymeric or ceramic body in a distal bone contacting region of the femoral stem. An elastic modulus is thereby engineered to match that of bone tissue. The porous sintered titanium body is created by sintering spheres of titanium. It is bonded to a central solid biocompatible metallic body by diffusion bonding. The distal region has a biocompatible polymeric body or biocompatible cement body. When compression molded the distal region develops an elastic modulus matching that of bone tissue. The proximal region has a porosity designed to encourage bone ingrowth.
