Systems and methods for providing a modular femoral component
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.
1. A modular component, comprising:
an articular surface configured to be disposed at a proximal portion of a posterior condyle of a femoral component to increase an articulation surface of the femoral component.
2. The component of claim 1 , wherein the modular component is configured to anteriorly extend an articulation surface of a lateral posterior condyle of the femoral component.
3. The component of claim 1 , wherein the modular component is configured to anteriorly extend an articulation surface of a medial posterior condyle of the femoral component.
4. The component of claim 1 , wherein a portion of the modular component is configured to extend into a recess in a non-articular surface of the femoral component.
5. The component of claim 1 , wherein the articular surface of the modular component comprises an incurved articular surface that is configured to articulate against at least one of a tibia and a tibial component.
6. The component of claim 5 , wherein the modular component is configured to increase the articulation surface of the femoral component at a medial posterior condyle.
7. The component of claim 1 , wherein the modular component comprises a flanged portion that is configured to extend anteriorly from an interior surface of the posterior condyle of the femoral component.
8. The component of claim 1 , wherein a non-articular portion of the modular component is configured to be disposed between a resected portion of a femur and a non-articular surface of the femoral component.
9. A modular component, comprising:
an articular surface configured to extend an articulation surface of a proximal portion of a posterior condyle of a femoral component, the modular component being configured to be attachable at a distal end of a femur such that a portion of the modular component extends anteriorly from the posterior condyle.
10. The component of claim 9 , wherein a portion of the modular component is configured to extend into a portion of the femoral component.
11. The component of claim 9 , wherein the articular surface of the modular component comprises an incurved articular surface that is configured to articulate against at least one of a tibia and a tibial component.
12. The component of claim 11 , wherein the modular component is configured to increase an articulation surface of the femoral component at a medial posterior condyle.
13. The component of claim 9 , wherein a width of a portion of the articular surface of the modular component is configured to substantially match a width of a portion of the proximal portion of the posterior condyle.
14. The component of claim 9 , wherein a non-articular portion of the modular component is configured to be disposed between a resected portion of the femur and a non-articular surface of the femoral component.
15. The component of claim 9 , wherein the femoral component comprises a uni-compartmental femoral component.
16. A method for attaching a modular component to a distal portion of a femur, the method comprising:
obtaining a modular component comprising an articular surface configured to be disposed at a proximal portion of a posterior condyle of a femoral component to increase an articulation surface of the femoral component;
obtaining the femoral component with the posterior condyle;
preparing a femur by removing bone from a distal portion of the femur; and
attaching the femoral component and the modular component at the distal portion of the femur.
17. The method of claim 16 , further comprising forming a recess in the distal portion of the femur to receive a portion of the modular component.
18. The method of claim 16 , further comprising removing a portion of a popliteal surface of the femur.
19. The method of claim 16 , further comprising inserting a portion of the modular component into a recess in the femoral component.
20. The method of claim 16 , wherein the articular surface of the modular component comprises an incurved articular surface that is configured to articulate against a medial articular surface of at least one of a tibia and a tibial component.
