Abstract
A tibial component for use in a prosthetic knee implant is constructed of a one-piece unitary member of synthetic polymeric material including a bearing portion having bearing surfaces for accepting the load imposed by the femoral component of the prosthetic knee implant and a keel projecting axially downwardly from the bearing portion and having flanges extending from a generally centrally located post outwardly at an angle to one another to be placed beneath the bearing surfaces of the bearing portion for reinforcing the bearing portion against the load imposed by the femoral component during service, while providing strength as well as rigidity and added stability for providing a relatively inexpensive alternative to metallic tibial components in recipients where the levels of performance offered by the higher cost metallic tibial components are not required.
