Metal and plastic composite tibial component for knee joint |
摘要 |
A prosthetic joint component which is comprised of a metal retainer and a plastic bearing portion which is molded integrally onto the top surface of the metal retainer. The metal retainer includes a plurality of notches spaced apart from each other around the periphery of the retainer. The notches enable the plastic, during the molding process, to flow through the notches to create a thickness of plastic completely surrounding the upper surface and the peripheral edge of the retainer (or metal base plate) and terminating in a lower plastic rim surface which is flush with the perimeter of the lower surface of the metal base plate, forming a strong mechanical interlock between the metal and plastic portions of the prosthetic joint component.
