Claim:
A method of forming a femur implant comprising joining a femoral component including a pair of condyle surfaces and a cam box to a femoral sleeve assembly, the femoral sleeve assembly comprising: a monolithic foam femur sleeve, said femur sleeve comprising titanium or titanium alloy foam having a porosity of 50 to 85% and possessing: a proximal end, a distal end, an interior wall that defines an interior channel and extends from the proximal end to the distal end, a terraced outer surface that tapers such that said sleeve is widest at the distal end and most narrow at the proximal end, and a distal notch defined in the distal end, the distal notch extending from anterior to posterior and receiving the cam box of the femoral component, a titanium insert that has a porosity of less than 10% and is positioned within said sleeve such that a portion of the titanium insert is exposed within said outer surface, and a femoral adapter that is affixed to the titanium insert, the femoral adaptor having a channel extending therethrough.
