An orthopaedic prosthesis including a tibial tray is disclosed. The tibial tray includes a distal pocket and a plurality of inner pockets. Each inner pocket includes a channel sized to receive bone cement. The tibial tray includes distal-facing surfaces that have a surface roughness (Ra) equal to about 5.0 microns.

Patella clamp

An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

Orthopaedic knee prosthesis having controlled condylar curvature

An orthopedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

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.
