A provisional prosthetic system that replicates the characteristics of a corresponding, nonprovisional femoral prosthesis. The provisional prosthetic system may include a frame component and a shell component. The frame component of the provisional prosthetic system may be configured to be attached directly to a resected femur. In one exemplary embodiment, the frame component is impacted onto the resected femur to firmly seat therewith. Once the frame component is secured to the resected femur, a shell component of the provisional prosthetic system may be positioned on and secured to the frame component. In one exemplary embodiment, the frame component is made from a metallic material. This allows for the frame component to maintain the rigidity necessary to facilitate proper trialing. In another exemplary embodiment, the shell component is a plastic.

Modular femoral provisional

The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.

Modular stem extension

A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.

A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available.

An easily assembled provisional orthopaedic implant having first and second components. The first component may include a stem which can be inserted into an intramedullary canal and may be a femoral component of a knee joint prosthesis. The second component has a body and a sliding retention member. The retention member can be manually engaged with a groove on the stem of the first component to lock the two components together. The second component may form of an intercondylar box and have a projecting tab engageable with a recess on the femoral component to properly orient the two components when they are placed in registry with each other.
