Prosthetic component with crosslinked polymer wear zone and edge protection

摘要

A method of manufacturing a prosthetic component comprises providing crosslinked polymer in a mould and moulding non-crosslinked polymer to a free edge of the crosslinked polymer to form a hybrid component. A portion of the crosslinked polymer and a portion of the non-crosslinked polymer are then removed so as to form a prosthetic component having a full thickness crosslinked wear zone 40 and at least one non-crosslinked edge 42. The component may have a metal cup or base 10. The polymer may comprise an antioxidant such as Vitamin E. The component may undergo terminal radiation sterilization.
