1. A method for manufacturing a prosthetic component for replacing a part of a bone of a joint in a subject, the method comprising:
forming the prosthetic component to include a base surface and an opposed articular surface wherein a width of the base surface is a predetermined percentage of a length of a neutral face plate line, the length of the neutral face plate line having been determined by (i) obtaining an image of the bone of the joint, (ii) orienting on the image a reference angle from a body of the bone to create the neutral face plate line, wherein the neutral face plate line is a straight line positioned within a perimeter of the image of the bone and extends from a first border of the bone to an opposite second border of the bone, and (iii) measuring the length of the neutral face plate line, wherein the neutral face plate line corresponds to a width of a flat neutral face plate formed by removing a portion of the bone during arthroplasty.
