1. A method for positioning a profile of a prosthetic component on a three-dimensional model of a limb, the method comprising: a. gathering patient-specific anatomical data of said limb; b. identifying first and second anatomical landmarks to determine a first spatial relationship; c. identifying a third anatomical landmark to determine a second spatial relationship with respect to said first spatial relationship; d. using at least the first and second spatial relationships to determine a positioning of the profile of the prosthetic component in all but one degree of freedom; and e. identifying a fourth anatomical landmark and, after determining the positioning of the profile of the prosthetic component in all but one degree of freedom, using the fourth anatomical landmark to determine a positioning of said profile of said prosthetic component in said one remaining degree of freedom.
