Antioxidant doping of crosslinked polymers to form non-eluting bearing components |
abstract |
Methods provide a non-eluting antioxidant doped UHMWPE in the form of an implant bearing component. The process includes the steps of: (a) providing a preform; (b) irradiating the preform with γ-irradiation to crosslink the UHMWPE; (c) doping the crosslinked preform by exposing it to an antioxidant composition at a temperature below the melting point of the UHMWPE; (d) removing the doped material from contact with the antioxidant composition; and then (e) annealing by heating the doped material at a temperature above 30° C. and below the melting point of the UHMWPE; followed by (f) making an implant bearing component from the doped material, wherein at least 1 mm but no more than about 15 mm of material are removed to make the component. |
