Patent ID: 7150761

Claim:
A femoral knee prosthesis system for resurfacing a resected articular surface at the distal end of a femur, the prosthesis system comprising: a femoral component having (i) an interior surface adapted to mate with the resected articular surface and (ii) an opposing articulating surface, the femoral component further comprising: a first portion comprising a first section of the articulating surface, a first section of the interior surface, and a first mating surface that extends between the first section of the interior surface and the first section of the articulating surface; a second portion comprising a second section of the articulating surface, a second section of the interior surface, and a second mating surface that extends between the second section of the interior surface and the second section of the articulating surface, the second portion comprising a substantially U-shaped lateral condyle and a substantially U-shaped medial condyle with a channel formed therebetween, wherein the first mating surface outwardly projects in a single substantially V-shaped configuration that continuously extends between opposing sides of the femoral component and the second mating surface has a single complementary recessed substantially V-shaped configuration that continuously extends between opposing sides of the femoral component, the first mating surface biasing against the second mating surface; a first fastener that extends through a portion of the first mating surface and the second mating surface so as to connect the first portion to the second portion; and a blind hole formed on the interior surface of the femoral component, the blind hole being threaded; and an elongated attachment mechanism having a first end and an opposing second end, the first end being threaded and adapted to be secured by threaded engagement within the blind hole after the interior surface of the femoral component is mated with the resected articular surface, an enlarged head being positioned at the second end of the attachment mechanism, the blind hole being threaded prior to mating with the attachment mechanism.
