Abstract

A system, method for replacing at least a portion of first articular surface cooperating with a second articular surface including a prosthetic implant. The method including creating a socket in the first articular surface generally opposite the prosthetic implant. A graft of biological material is installed in the socket, providing a biological replacement of a portion of the first articular surface.

Claims

1. A method for replacing a portion of an articular surface comprising:

forming a prosthetic implant, said prosthetic implant configured to be at least partially received in a first articular surface; and

forming a biological graft configured to be at least partially received in a second articular surface, said second articular surface cooperating with said first articular surface configured to receive said prosthetic implant.

2. The method according to claim 1, wherein said graft of biological material comprises a living human tissue autograft.

3. The method according to claim 1, wherein said graft of biological material comprises a living human tissue autograft comprising joint capsular tissue.

4. The method according to claim 1, wherein said graft of biological material comprises a living human tissue autograft comprising tendons or tendon sheaths.

5. The method according to claim 1, wherein said graft of biological material comprises a living human tissue allograft.

6. The method according to claim 1, wherein said graft of biological material comprises materials derived from human tissue.

7. The method according to claim 1, wherein said graft of biological material comprises an acellular scaffold derived from human tissue.

8. The method according to claim 1, wherein said biological material comprises tissue derived from bovine or equine sources.

9. The method according to claim 1, further comprising forming a socket in said second articular surface for receiving said biological implant, comprising resecting a portion of said second articular surface comprising a damaged region opposite said prosthetic implant.

10. The method according to claim 9, further comprising anchoring said graft of biological material in said socket.

11. A system for repairing a first and second cooperating articular surface, the system comprising:

a prosthetic implant configured to replace at least a portion of said first articular surface; and

a graft of biological material configured to replace at least a portion of said second articular surface cooperating with, at least in part, said prosthetic implant.

12. A system according to claim 11, wherein said graft of biological material comprises a living human autograft.

13. A system according to claim 11, wherein said graft of biological material comprises a living human tissue allograft.

14. A system according to claim 11, wherein said graft of biological material comprises tissue derived from human tissue.

15. A system according to claim 11, wherein said graft of biological material comprises tissue derived from bovine or equine sources.

16. A system according to claim 11, wherein said graft of biological material comprises a plug of biological material and a ring configured to receive at least a portion of said plug.

17. A system according to claim 16, wherein said ring is crimped onto said plug of biological material.

18. A system according to claim 16, wherein said ring comprises an outward projection configured to promote retention of said graft in a socket in said second articular surface.

19. A system according to claim 11, wherein said graft of biological material comprises a multi-layer structure, wherein at least a top layer comprises a biological material.

20. A system according to claim 11, wherein said graft of biological material comprises at least one ridge extending around at least a portion of a perimeter of said graft, said ridges configured to promote retention of said graft in a socket in said second articular surface.
