Abstract
An orthopaedic knee prosthesis includes a femoral component having a metal base with a polymer articular layer molded thereto. A method for making a metal-reinforced femoral component of an orthopaedic knee prosthesis is also disclosed.
Claims3
A method of making a femoral component of an orthopaedic knee prosthesis, the method comprising:
- disposing a porous-metal coating onto a metal base, the metal base having (i) a superior base surface that includes a number of bone fixation surfaces, and (ii) a number of lugs, and
- molding a polymer articular layer onto an inferior base surface of the metal base that is curved in the sagittal plane such that (i) a plurality of elongated ribs extending inferiorly from the inferior base surface are embedded in the polymer articular layer, and (ii) an outer surface of the polymer articular layer forms an articulation surface that is curved in the sagittal plane and configured to articulate with a bearing surface of a tibial component.
