Patent ID: 7615081

Claim:
A femoral knee prosthesis system for resurfacing a resected articular surface at the distal end of a femur, the prosthesis system comprising: a first femoral component portion having a first interior surface adapted to mate with the resected articular surface of the femur, an opposing first articulating surface, and a first mating surface that extends between the first interior surface and the first articulating surface; a second femoral component portion having a second interior surface adapted to mate with the resected articular surface of the femur, an opposing second articulating surface, and a second mating surface that extends between the second interior surface and the second articulating surface, the second femoral component portion comprising a substantially U-shaped lateral condyle and a substantially U-shaped medial condyle with a channel formed therebetween, the second femoral component being an integral, unitary member; a first blind socket and a spaced apart second blind socket formed on the first mating surface or the second mating surface, the first blind socket and the second blind socket each being bounded by an encircling sidewall; a first projection and a spaced apart second projection projecting from the first mating surface or the second mating surface such that the first projection and the second projection can be selectively received within the first blind socket and the second blind socket so as to mate the first femoral component portion with the second femoral component portion; and means for securely connecting the first femoral component portion to the second femoral component portion when the first projection and the second projection are received within the first blind socket and the second blind socket; the first femoral component portion and the second femoral component portion forming an end use femoral component when connected together.
