US Patent 6962607 Joint replacement prosthesis component with non linear insert

According to one embodiment of the present invention, there is provided a joint prosthesis (10) having a first component (12) for cooperation with a first long bone (14) and a second component (16) for cooperation with a second long bone (20). The joint prosthesis (10) further includes a bearing component (22) positionable between the first component (12) and the second component (16) and cooperable with the first component (12) and the second component (16). The bearing component (22) includes a reinforcing component (36) having a first portion (54) defining a first centerline (50) and having a second portion (56) defining a second centerline (52). The first centerline (50) and the second centerline (52) are non-coincidental. The bearing component (22) includes a polymeric material (112) surrounding the reinforcing component (36) and molded to the reinforcing component (36). The bearing component (22) defines a first peripheral region (34) adjacent the first portion (54) of the reinforcing component (36) and a second peripheral region (82) adjacent the second portion (56) of the reinforcing component(36). The first peripheral region (34) cooperates with first component (12) and the second peripheral region (82) cooperates with the second component (16).
