Abstract:
1. A method of implanting a knee prosthesis in a tibia and a femur, the method comprising: attaching to the femur a femoral component comprising a condylar bearing surface and a hinge post rotatably connected to the femoral component about an axis of rotation, the hinge post including a tubular portion with an elongate aperture passing entirely therethrough, the elongate aperture defining a first end, a second end and an axis transverse to the axis of rotation: attaching to the tibia a tibial component having a tibial tray, the tibial tray having a superior surface, said attaching step done so that the superior surface is exposed; after said attaching steps, sliding, along a generally anteroposterior path between the condylar bearing surface and the superior surface of the tibial tray, a meniscal component having a meniscal bearing surface for cooperation with the condylar bearing surface of the femoral component, the meniscal component having an inferior surface opposite the meniscal bearing surface, the inferior surface adapted to slide along the superior surface of the tibial tray, the meniscal component having a meniscal aperture sized to receive the tubular portion of the hinge post and to allow rotation of the hinge post about the axis of rotation when the hinge post is received within the meniscal aperture; during said step of sliding the meniscal component and with the hinge post rotatably connected to the femoral component, positioning the tubular portion of the hinge post within the meniscal aperture; and coupling the hinge post to the tibial component.
