Abstract

A suture anchor for knotless fixation of tissue. A swivel suture anchor has a rotatable anchor tip for receiving a suture strand, for example a rotatable forked tip for capturing a suture chain, for surgical tissue repair without requiring suture knots. Tension on the repair constructs is adjustable through the selection of the specific chain link or links of the suture chain captured by the forked anchor tip of the suture anchor. The swivel anchor is secured in a hole in bone by advancing a fixation device, such as a cannulated interference screw, over the body of the anchor.

Claims

1. A suture anchor comprising:

an anchor body; and

an anchor tip for receiving a strand of suture, the anchor tip being rotatably attached to the anchor body.

2. The suture anchor of claim 1, wherein the suture anchor is configured to allowed rotational insertion without causing excessive twisting and knotting of a suture captured in the anchor tip.

3. The suture anchor of claim 1, wherein the anchor tip comprises a forked end configured to capture a suture.

4. The suture anchor of claim 1, wherein the anchor body is threaded.

5. The suture anchor of claim 1, wherein the anchor tip is detachable.

6. The suture anchor of claim 1, further comprising a fixation device for securing the suture anchor in a hole in bone.

7. The suture anchor of claim 6, wherein the fixation device is a cannulated interference screw.
