Abstract
A method of manufacturing a bearing component for use in arthroplasty for cooperation with a first and a second component includes the step of providing a non-linear support of a durable material having. The method further includes providing a molding die for manufacturing the bearing component having first and second mold portions. The first mold portion provides a first surface for cooperation with the first joint component and the second mold portion provides a second surface for cooperation with the second joint component. The method includes positioning the support in a desired position within the molding die with the first end or the second end located in the first mold portion, adding moldable material into the molding die, surrounding the support with the moldable material, heating and pressurizing the moldable material, permitting the moldable material to cool, and removing the component from the molding die.
