Abstract

A method for manufacturing a prosthetic component include injection molding a prosthetic component with a polymeric material. The prosthetic component includes a final surface positioned on one side and multiple coring features positioned on an opposite side. The coring features may include multiple ribs and slots. The method further includes machining the prosthetic component to remove the coring features and form a final surface on the opposite side. The prosthetic component may be a femoral component for a prosthetic knee joint.
