Abstract

Methods and devices for the repair of a ruptured ligament using a scaffold device are provided. Aspects of the invention may include a scaffold attached by one or more sutures to one or more anchors. In aspects of the invention, the anchors may be secured to a bone near or at the repair site.

Claims (19)

1 . An arthroscopic repair system, comprising:

a tissue healing device configured to repair a tissue exposed to synovial fluid and attachable to a first bone and a second bone, the tissue healing device having:

a porous, hydrophilic implantable material comprising collagen and configured to be positioned between a ruptured end of the tissue and the second bone,

at least one anchor having an eyelet and configured to be secured to the second bone, and

at least one suture configured to be threaded through or along the implantable material to position the implantable material between the ruptured end of the tissue and the second bone, the at least one suture being threadable through the at least one anchor via the eyelet;

wherein the implantable material is configured to repair tissue when positioned adjacent to the ruptured end of the tissue.

2 . The system of claim 1 , wherein the implantable material is a scaffold.

3 . The system of claim 1 , wherein the tissue is an ACL and wherein the implantable material allows cell ingrowth.

4 . The system of claim 1 , wherein the at least one anchor is conical in shape.

5 . The system of claim 1 , wherein each of the at least one anchor includes a first end and a second end opposite the first end.

6 . The system of claim 5 , wherein the eyelet is disposed at the first end of one of the at least one anchor.

7 . The system of claim 6 , wherein the at least one suture is attached to the at least one anchor through the eyelet.

8 . The system of claim 5 , wherein the at least one anchor includes a sharpened tip at the second end of the at least one anchor.

9 . The system of claim 8 , wherein the sharpened tip is threaded.

10 . The system of claim 1 , wherein the at least one anchor is a screw.

11 . The system of claim 1 , where the implantable material further comprises a repair material.

12 . The system of claim 11 , where the repair material is a platelet or plasma.

13 . The system of claim 11 , wherein the tissue healing device further includes one or more growth factors configured to be disposed within or on the implantable material.

14 . The system of claim 11 , wherein the implantable material consists essentially of a porous collagen sponge.
