Abstract: Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a modular component, wherein the modular component is configured to attach to a femoral component, and wherein the femoral component is configured to attach to a distal portion of a femur. In some cases, the modular component includes an articular surface that is configured to increase a surface area of an articulation surface of a proximal portion of a posterior condyle of the femoral component. Other implementations are also discussed.

Abstract: 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.

Abstract: Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a tibial component that has an asymmetrical articular plateau that includes a medial tibial condylar surface and a lateral tibial condylar surface. In some cases, at least one of the medial condylar surface and the lateral condylar surface includes a concave articulation surface having a lowest point that disposed from a posterior edge of the tibial component by between about 18% and less than about 35% of a total anteroposterior dimension of the tibial component. Other implementations are also discussed.

Abstract: 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.

In some instances, such systems and methods include an asymmetrical femoral component that includes a femoral prosthesis that is configured to attach to a distal portion of a femur. In some such instances, the prosthesis includes a medial condyle and a lateral condyle, wherein a medial-lateral width of an articulation surface of the lateral condyle is approximately 75% or less of a medial-lateral width of an articulation surface of the medial condyle. Other implementations are also discussed.

Abstract: Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a resection block for resectioning a popliteal surface of a femur. In some cases, the resection block is configured to be seated on a distal portion of a femur. Additionally, some implementations of the resection block define a first slot that is sized and shaped to receive a cutting device. In some implementations, the first slot is defined in the resection block such that the first slot substantially aligns with a first portion of a popliteal surface of the femur when the resection block is seated on the distal portion of the femur. Other implementations are also discussed.

Abstract: 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.

Abstract: 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.
