摘要： This invention relates to a floating bearing knee joint prosthesis (146) having a fixed tibial post used for replacing the articulating knee portion of a femur and a tibia. The floating bearing knee joint prosthesis (146) includes a femoral component (152), a tibial component (154), a guide post (206) and a bearing member (156). The femoral component (152) includes an engagement member (176), a first femoral bearing surface (162) and a second femoral bearing surface (164). The tibial component (154) includes a tibial bearing surface (196). The guide post (206) extends from the tibial component (154) and is operable to be engaged by the engagement member (176) of the femoral component (152). The bearing member (156) includes a first bearing surface (200) that articulates with the first femoral bearing surface (162), a second bearing surface (202) that articulates with the first femoral bearing surface (164) and a third bearing surface (198) that articulates with the tibial bearing surface (196). The bearing member (156) further includes a posterior lip extension (284) that substantially inhibits the bearing member (156) from dislocating upon flexion of the knee prosthesis (146).

摘要： A floating bearing knee joint prosthesis (10) having a fixed tibial post used for replacing the articulating knee portion of a femur, and a tibia. The floating bearing knee joint prosthesis (10) includes a femoral component (16), a tibial component (18), a bearing member (20), and a guide post (64). The femoral component (16) includes an engagement member (40), a first femoral bearing surface (22), and a second femoral bearing surface (24). The tibial component (18) includes a tibial bearing surface. The bearing member includes a first bearing surface (54) which is operable to articulate with the first femoral bearing surface (22), a second bearing surface (60) which is operable to articulate with the second femoral bearing surface (24), and a third bearing surface (58) which is operable to articulate with the tibial bearing surface (56). The guide post (64) extends from the tibial component, and is operable to be engaged by the engagement member (40) of the femoral component such that upon engagement, the femoral component forces the bearing member to move posteriorly relative to the tibial component.
