Abstract
A prosthetic knee system has a tibial component and a modular sleeve. The tibial component has a tibial tray, a stem and keels extending between the distal surface of the tray and the stem. The modular sleeve has an oval proximal surface with spaced reliefs. The reliefs and keels are sized, shaped and positioned to allow the modular sleeve to be mounted on the tibial component with the stem of the tibial component received in the interior channel of the sleeve and the keels of the tibial component received in the spaced reliefs of the modular sleeve, and to allow for some relative rotation between the tibial component and the sleeve. The system gives the surgeon the freedom to implant the tibial component alone, with the keels providing stability, or, in the case of bone deficiency, to implant the tibial component and sleeve as an assembly.
