<p>A method of manufacturing a polymeric bearing component (22) for use in joint arthroplasty for cooperation with a first joint component (12) and a second joint component (16) includes the step of providing a non-linear reinforcing support (36) of a durable material having a first end (86) and a second end (94). The method further includes the step of providing a moulding die (62) adapted for manufacturing the bearing component (22) for use in total joint arthroplasty and having a first mould portion (66) and a second mould portion (76). The first mould portion (66) is adapted to provide a first surface (70) of the bearing component (22) for cooperation with the first joint component (12) and the second mould portion (76) is adapted to provide a second surface (80) of the bearing component (22) for cooperation with the second joint component (16). The method further includes the steps of positioning the support in a desired position within the moulding die (62) with one of the first end (86) and the second end (94) located in the first mould portion (66), adding mouldable polymeric material into the moulding die (62), substantially surrounding the support with the mouldable material, heating and pressurizing the mouldable material, permitting the mouldable material to cool to form the bearing component (22), and removing the component (22) from the moulding die (62). <IMAGE></p> |
