Patent ID: 7799084

Claim:
A femoral component for a total knee joint replacement comprising, a plurality of segments, each of said segments having a femoral fixation surface adapted to be positioned on a distal end of a femur and at least one assembly surface adapted to be joined to an assembly surface of an adjacent one of said segments said assembly surface being generally planar and arranged to be oriented generally in a plane extending in a proximal-distal direction and in an anterior-posterior direction when said femoral fixation surface is positioned on said distal end of said femur, wherein at least two adjacent segments each comprise a bearing surface on an anterior portion of said component, said assembly surfaces of said segments being in mutual contact and said bearing surfaces of said adjacent segments being positioned to form a generally continuous bearing surface on an anterior portion of said component, wherein edges of said mutually contacting assembly surfaces on portions of the assembly surfaces closest to the generally continuous bearing surface are recessed below said generally continuous bearing surface on an anterior portion of said component, wherein each of said plurality of segments is configured to be separately inserted through an incision in a person and assembled to another of the plurality of segments after insertion through the incision, wherein the assembly surface of each segment has a beveled corner.
