A method of implanting a prosthesis based on bone density of a bone is provided. A first bone density of the bone may be determined at a first portion of the bone. A second bone density of the bone may be determined at a second portion of the bone. A first desired amount of bone removal may be determined at the first portion of the bone based on the first bone density. A second desired amount of bone removal may be determined at the second portion of the bone based on the second bone density. The desired amounts of bone may be removed from the first and second portions of the bone. A prosthesis may be selected and implanted.
