Abstract

An assembly for meniscal repair including a first tissue fixation member configured to secure a meniscal tissue, a suture anchor having a proximal end, a distal end, a central axis defined therethrough, an eyelet on the proximal end of the suture anchor, and a textured outer surface, and a first suture configured to be coupled to the first tissue fixation member and configured to be received through the eyelet of the suture anchor.

Claims

1. An assembly for meniscal repair comprising:

a first tissue fixation member configured to secure a meniscal tissue;

a suture anchor comprising a proximal end, a distal end, a central axis defined therethrough, an eyelet, and a textured outer surface; and

a first suture configured to be coupled to the first tissue fixation member and configured to be received through the eyelet of the suture anchor.

2. The assembly of claim 1, further comprising a second tissue fixation member configured to secure a meniscal tissue.

3. The assembly of claim 2, further comprising a second suture to be coupled to the second tissue fixation member and configured to be received through the eyelet of the suture anchor.

4. The assembly of claim 1, wherein the textured outer surface is located near the distal end of the suture anchor.

5. The assembly of claim 1, wherein the textured outer surface of the suture anchor is a threaded outer surface.

6. The assembly of claim 1, wherein the textured outer surface is a stepped outer surface.

7. The assembly of claim 1, further comprising a fixation plug.

8. The assembly of claim 7, wherein the suture anchor comprises a longitudinal hole formed along the central axis of the suture anchor configured to receive the fixation plug.

9. The assembly of claim 8, wherein the fixation plug is configured to secure at least one suture within the eyelet of the suture anchor.

10. The assembly of claim 8, wherein the longitudinal hole formed through the suture anchor is a threaded hole.

11. The assembly of claim 10, wherein the fixation plug comprises a threaded outer surface configured to engage with the threaded hole of the suture anchor.

12. A method for meniscal repair comprising:

providing a first tissue fixation member configured to secure a meniscal tissue, a suture anchor having an eyelet, and a first suture;

securing the first suture to the first tissue fixation member;

securing the first tissue fixation member to a meniscal tissue;

threading the first suture through the eyelet of the suture anchor;

securing the suture anchor within a bone; and

tensioning the first suture within the suture anchor.

13. The method of claim 12, further comprising making a single incision into a skin and forming a portal into a body.

14. The method of claim 12, further comprising forming a hole within the bone.

15. The method of claim 13, further comprising engaging the first tissue fixation member and a delivery device and disposing the delivery device and the first tissue fixation member through the portal, into the body.

16. The method of claim 12, further comprising:

securing a second suture to a second tissue fixation member;

threading the second suture through the eyelet of the suture anchor; and

tensioning the second suture within the suture anchor.

17. The method of claim 16, further comprising engaging the second tissue fixation member and the delivery device and disposing the delivery device and the second tissue fixation member through the portal, into the body.

18. The method of claim 15, further comprising disengaging the first tissue fixation member from the delivery device and removing the delivery device from the body.

19. The method of claim 17, further comprising disengaging the second tissue fixation member from the delivery device and removing the delivery device from the body.

20. A kit for meniscal repair comprising:

at least one tissue fixation member configured to secure a meniscal tissue;

a suture anchor comprising an eyelet;

at least one suture configured to be coupled to the at least one tissue fixation member and configured to be received through the eyelet of the suture anchor; and

a delivery device configured to assist with delivery of the at least one tissue fixation member into a body.
