A joint prosthesis has a first component for cooperation with a first long bone, a second component for cooperation with a second long bone, and a bearing component positionable between the first component and the second component. The bearing component includes a reinforcing component and a polymeric material completely encapsulating the reinforcing component and molded thereto. The bearing component may be sterilized by a predominately surface sterilizing technology.

Prosthetic bearing with encapsulated reinforcement

According to one embodiment of the present invention, there is provided a joint prosthesis () having a first component () for cooperation with a first long bone () and a second component () for cooperation with a second long bone (). The joint prosthesis () further includes a bearing component () positionable between the first component () and the second component () and cooperable with the first component () and the second component (). The bearing component () includes a reinforcing component () having a first portion () defining a first centerline () and having a second portion () defining a second centerline (). The first centerline () and the second centerline () are non-coincidental. The bearing component () includes a polymeric material () surrounding the reinforcing component () and molded to the reinforcing component (). The bearing component () defines a first peripheral region () adjacent the first portion () of the reinforcing component () and a second peripheral region () adjacent the second portion () of the reinforcing component(). The first peripheral region () cooperates with first component () and the second peripheral region () cooperates with the second component ().

Joint replacement prosthesis component with non linear insert

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.
