Abstract

A method for securing soft tissue to bone which does not require the surgeon to tie suture knots to secure the tissue to the bone. A pilot hole or socket is created in the bone at the location that the graft is to be secured. Suture is passed through the graft at desired points. A cannulated plug or screw is pre-loaded onto the distal end of a driver provided with an eyelet implant at its distal end. Suture attached to the graft is passed through the eyelet of the implant located at the distal end of the driver. The distal end of the driver together with the eyelet implant is inserted into the bottom of the hole, with the screw or plug disposed just outside the hole. Tension is applied to the suture to position the graft at the desired location relative to the bone hole. The screw or plug is then frilly advanced into the pilot hole by turning the interference screw or tapping the plug until the cannulated screw or plug securely engages and locks in the eyelet implant, so that the cannulated plug or screw with the engaged eyelet implant is flush with the bone. Once the screw or plug is fully inserted and the suture is impacted into the pilot hole, the driver is removed and any loose ends of the sutures protruding from the anchor site are then clipped short.

Claims

1. A system for interference fixation of a suture in a hole in bone, the system comprising:

a driver including a shaft having a proximal end and a distal end;

a cannulated interference device preloaded on the driver and disposed coaxially with the shaft, the cannulated interference device having an inner diameter and an outer diameter; and

an implant containing an aperture, the aperture being located at most distal end of the implant and being configured to capture suture, said implant being releasably attached at the distal end of the driver and having a width smaller than the inner diameter of the cannulated interference device.

2. The system of claim 1, wherein the interference device is a screw.

3. The system of claim 1, wherein the interference device is a plug.

4. The system of claim 1, wherein the aperture is provided in the shape of a horseshoe.

5. The driver of claim 1, wherein the aperture of the implant has an eyelet configuration.

6. The system of claim 1, wherein the implant is releasably attached to the driver by a connector portion that fits within a tubing integral to the distal end of the driver.

7. A method of soft tissue repair, comprising the steps of:

providing a hole in a bone at a location at which a soft tissue graft is to be affixed;

attaching at least one suture to the soft tissue graft to be affixed;

preloading a cannulated interference device on a shaft of a driver;

capturing the suture attached to the graft by feeding the suture through an aperture of an implant, said implant being releasably attached at a distal end of the driver;

inserting the suture into the hole by inserting the distal end of the driver into the hole;

pulling on one end of the suture to draw the suture through the aperture of the implant such that the soft tissue graft attached to the suture is drawn toward the hole; and

inserting the interference device into the hole so that the cannulated interference device is advanced toward the implant to secure the suture in the hole.

8. The method of soft tissue repair according to claim 7, wherein the interference device is a screw.

9. The method of soft tissue repair according to claim 7, wherein the interference device is a plug.

10. The method of soft tissue repair according to claim 7, wherein the aperture has an eyelet configuration.

11. The method of soft tissue repair according to claim 7, wherein the aperture has a horseshoe-shaped configuration.

12. The method of soft tissue repair according to claim 7, wherein the aperture is provided with at least one protuberance at its distal end.

13. The method of soft tissue repair according to claim 7, wherein the driver includes an outer shaft disposed around an inner shaft and movable between a proximal position and a distal position along the inner shaft, and wherein the interference device is loaded onto the inner shaft by inserting the inner shaft through a cannula of the interference device with the outer shaft retracted to the proximal position so that the proximal end of the loaded interference device abuts the distal end of the outer shaft.

14. The method of soft tissue repair according to claim 13, wherein the interference device is a screw having a hex-shaped cannula and at least a portion of the implant at the distal end of the driver is hex-shaped to be matingly insertable into the hex-shaped interference screw cannula.

15. The method of soft tissue repair according to claim 7, wherein the soft tissue graft is drawn into the hole by pulling on the suture, and the interference device secures not only the suture but also the graft in the hole.

16. The method of soft tissue repair according to claim 7, wherein the interference device is inserted into the hole by impaction.
