Abstract:
1. A distal femoral component of a knee prosthesis comprising: a lateral condylar structure having a lateral condylar surface, a posterior portion, a posterior condylar apex, a lateral side and a bone facing surface; a medial condylar structure having a medial condylar surface, a posterior portion, a posterior condylar apex, a medial side and a bone facing surface, said medial condylar surface being generally spherical, wherein the posterior portion of each of the lateral and medial condylar structures defining a posterior condylar surface; an anterior flange connecting the lateral condylar structure and the medial condylar structure, wherein the anterior flange having an anterior condylar surface, an interior surface and a proximal tip of the interior surface; a measured anterior/posterior dimension defined by the posterior condyle surface and the proximal tip of the interior surface of the anterior flange; and a distal peg provided on the bone facing surface of each of the lateral and medial condylar structures, wherein the distal pegs are positioned at a midline of the measured anterior/posterior dimension for enabling midline-referenced sizing scheme for the femoral component.
