A suture anchor for knotless fixation of tissue. The suture anchor includes an implant configured to hold a suture to be anchored in bone without requiring suture knots. The suture is secured in bone by inserting the implant holding the suture into a hole in the bone, and advancing a fixation device, such as a cannulated interference screw, over a shaft at the proximal end of the implant.

Suture anchor for knotless fixation of tissue

A swivel suture anchor for knotless fixation of tissue. The suture anchor includes an anchor tip configured to capture suture, the anchor tip being rotatably received within a fixation device upon advancement of the fixation device over a shaft of the anchor tip. The anchor tip is configured to receive a suture to be anchor in bone without requiring suture knots. The anchor tip can be a conical metal tip which is self-punching and avoids the need for pre-drilling a hole in bone. The anchor tip includes a closed aperture to allow free sliding of a suture strand. The suture is secured in a hole in bone by inserting the anchor tip into bone, and advancing a fenestrated fixation device, such as a cannulated interference screw, over a shaft of the anchor tip.

Swivel anchor for knotless fixation of tissue

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. Suture is passed through the tissue 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 tissue 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 bone. Tension is applied to the suture to position the tissue at the desired location relative to the bone. The screw or plug is 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 secured in the bone, the driver is removed and any loose ends of the sutures protruding from the anchor site are then clipped short.
