    摘要： A posterior stabilized knee orthopaedic prosthesis assembly includes a tibial bearing, a primary femoral component, and a revision femoral component. Each of the primary and revision femoral components is configured to separately articulate with the tibial bearing. However, each of the primary and revision femoral components has different geometry. The primary femoral component includes a posterior cam having a posterior cam surfacing including a concave cam surface and a convex cam surface. The revision femoral component includes a posterior cam having only a convex cam surface.

    摘要： An implantable orthopaedic knee prosthesis assembly includes a femoral component, a stem component, a fastener, and a retention device. The femoral component is configured to be implanted into a distal end of a femur of a patient and includes a stem post having a proximal tapered bore, a distal passageway, and a threaded passageway connecting the proximal tapered bore and the distal passageway. The stem component is configured to taper fit to the femoral component and includes a bore formed therein extending proximally and a threaded aperture defined at a proximal end of the bore. The head of the fastener is configured to be received in the distal passageway, whereas the proximal end of the shaft of the fastener is configured to be positioned in the threaded aperture. The retention device is received in the threaded passageway and prevents the proximal end of the fastener from reentering the threaded passageway.

    摘要： A posterior stabilized knee orthopaedic prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The tibial bearing includes a spine having a concave cam surface and a convex cam surface. The femoral component includes a posterior cam having a concave cam surface and a convex cam surface. During flexion, the concave cam surface of the posterior cam contacts the convex cam surface of the spine and the convex cam surface of the posterior cam contacts the concave cam surface of the spine.
