Abstract

A kit for a prosthesis system includes a plurality of first components, each of the plurality of first components for replacing one of a plurality of first surface portions of a bone, a second component for replacing a second surface portion of the bone and a resilient connector for connecting at least one of the plurality of first components to the second component. In accordance with one method, components from a prosthesis system kit used to replace adjacent portions of a bone surface are assembled ex vivo.

Claims

1. A kit for a prosthesis system comprising:

a plurality of first components, each of the plurality of first components for replacing one of a plurality of first surface portions of a bone;

a second component for replacing a second surface portion of the bone; and

a first resilient connector for connecting at least one of the plurality of first components to the second component.

2. The kit of claim 1, wherein the resilient connector comprises a spacer.

3. The kit of claim 1, further comprising:

a third component for replacing a third surface portion of the bone; and

a second resilient connector for connecting the third component to at least one of the plurality of first components.

4. The kit of claim 1, wherein the first resilient connector is operable to connect each of the plurality of first components with the second component.

5. The kit of claim 1, wherein the plurality of first components comprises:

a first patellofemoral joint (PFJ) component for replacing a first surface portion of a PFJ; and

a second PFJ component for replacing a second surface portion of the PFJ.

6. The kit of claim 1, wherein the first PFJ component comprises a node.

7. The kit of claim 5, further comprising:

a third resilient connector for connecting the first PFJ component to the second PFJ component.

8. The kit of claim 5, wherein the first resilient connector is operable to connect the first PFJ component to the second PFJ component.

9. A method of configuring a prosthesis system comprising:

selecting one of a plurality of first components in a kit for replacing a first surface portion of a bone;

selecting one of a plurality of second components in the kit for replacing a second surface portion of the bone; and

connecting the selected first component to the selected second component with a first resilient connector.

10. The method of claim 9, wherein the step of connecting is performed ex vivo.

11. The method of claim 9, further comprising,

selecting one of a plurality of third components in the kit for replacing a third surface portion of the bone;

and

connecting the selected third component to the selected first component with a second resilient connector.

12. The method of claim 9, wherein connecting the selected first component comprises selecting the first resilient connector from a plurality of resilient connectors in the kit, each of the plurality of resilient connectors comprising a spacer having a width different from the spacers of each of the other of the plurality of resilient connectors.

13. The method of claim 9, wherein:

selecting one of a plurality of first components comprises selecting a first patellofemoral joint (PFJ) component for replacing a first surface portion of a PFJ; and

selecting one of a plurality of second components comprises selecting a second PFJ component for replacing a second surface portion of the PFJ.

14. A method for implanting a prosthesis system comprising:

making an incision;

selecting a first component having a bone mounting surface, a bone surface replacement surface, a first side adjacent to the bone mounting surface and the bone surface replacement surface, and a second side adjacent to the bone mounting surface and the bone surface replacement surface;

selecting a second component having a bone mounting surface, a bone surface replacement surface, and a side adjacent to the bone mounting surface and the bone surface replacement surface;

connecting the first component and the second component such that the first side of the first component is in opposition to the side of the second component;

inserting the connected first component and second component through the incision; and

mounting the first and the second component on a bone such that the bone mounting surface of the first component and the bone mounting surface of the second component are in opposition to the bone.

15. The method of claim 14, wherein mounting the first and the second component comprises:

mounting the connected first and second components on the bone such that the first component replaces a portion of a patellofemoral compartment and the second component replaces a portion of a condylar compartment.

16. The method of claim 14, further comprising:

selecting a third component having a bone mounting surface, a bone surface replacement surface, and a side adjacent to the bone mounting surface and the bone surface replacement surface; and

connecting the third component with the first component and the second component such that the side of the third component is in opposition to the second side of the first component, and wherein inserting comprises,

inserting the connected first component and second component and third component through the incision, and wherein mounting comprises,

mounting the first, the second and the third component on a bone such that the bone mounting surface of the first component and the bone mounting surface of the second component and the bone mounting surface of the third component are in opposition to the bone.

17. The method of claim 16, wherein mounting comprises:

mounting the connected first, second and third components on the bone such that the first component replaces a portion of a patellofemoral compartment, the second component replaces a portion of a first condylar compartment, and the third component replaces a portion of a second condylar compartment.

18. The method of claim 14, further comprising:

selecting a connector component, and wherein connecting the first component and the second component comprises;

connecting the first component to the connector component; and

connecting the second component to the connector component.

19. The method of claim 18, wherein selecting a connector component comprises selecting a connector component with an integrated spacer.

20. The method of claim 18, wherein connecting comprises connecting the first component and the second component with a resilient connector.
