A method of implanting a hip prosthesis includes utilization of a device at the implantation site to confirm that the femoral prosthesis will have a neck length corresponding to a preoperative plan. First, a desired neck size for the femoral prosthesis is determined. Then, the femoral prosthesis is positioned in the femur. Next, a locator rod component is advanced toward the femoral prosthesis along an axis parallel to the longitudinal axis of the femoral prosthesis until a greater trochanter locator mounted on the side of the locator rod component is as close as possible to contacting the greater trochanter of the femur. Next, a neck sizing component, which has neck size markings on its outer surface, is placed on the neck projection of the femoral prosthesis. Finally, a reference distance is determined by identifying which of the reference distance markings of the locator rod component corresponds to a desired neck size marking on the neck measuring device along a line substantially perpendicular to the longitudinal axis of the femoral prosthesis. The determined reference distance should correspond to a planned reference distance that was determined in an appropriate preoperative templating and measuring procedure.

Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing and improved patellar tracking for knee prosthesis patients. Such systems and methods include (i) adding more articular surface to the antero-proximal posterior condyles of a femoral component, including methods to achieve that result, (ii) modifications to the internal geometry of the femoral component and the associated femoral bone cuts with methods of implantation, (iii) asymmetrical tibial components that have an unique articular surface that allows for deeper knee flexion than has previously been available, (iv) asymmetrical femoral condyles that result in more physiologic loading of the joint and improved patellar tracking and (v) modifying an articulation surface of the tibial component to include an articulation feature whereby the articulation pathway of the femoral component is directed or guided by articulation feature.

Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a knee prosthesis that includes a femoral component for replacing at least a portion of a distal end of a femur. In some cases, the femoral component has a posterior condyle that is configured to articulate against a tibial articular surface. In such cases, an articular surface at a proximal portion of the posterior condyle is sized and shaped to extend at least half of an antero-posterior distance between a most posterior portion of the posterior condyle and a plane that is a continuation of a distal one fourth to one third of a posterior cortex of a femoral shaft of the femur. Other implementations are also discussed.

An endoprosthetic ankle joint device comprises a talar component with a convex articulatory surface having an intermediate part-circular-cylindrical area coaxially flanked at each end by like mutually divergent part-conical areas, and a tibial component with an assymetrical concave articulatory surface complementary with said convex cylindrical area and one of said conical areas. In one form of the device the tibial concave surface has areas complementary with each of the talar conical areas, but to different extents, with the former areas being respectively axially longer and shorter. In another form, the tibial concave surface is only complementary with one of the talar conical areas, and the device comprises a fibular component for articulation with the other talar conical area.

Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a modular patella-femoral component. This modular patella-femoral component can include several characteristics, including a modular anterior flange that has an anterior femoral articulation surface that is configured to articulate against a patella in a knee joint, a posterior surface that is configured to be attached to an anterior portion of a femur, and a distal end that is configured to couple to a proximal end of an anterior portion of a femoral prosthesis, which is configured to couple to a distal portion of the femur. Other implementations are also described.

Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a femoral knee replacement component that includes an articular surface, a first interior surface, and a second interior surface, wherein the first and second interior surfaces run substantially parallel to each other. In some cases, the articular surface includes an anterior condylar extension that is configured to replace an anterior articular cartilage of a femur such that the anterior extension is configured to terminate adjacent to a proximal limit of the anterior articular cartilage of the femur. Other implementations are also discussed.
