Abstract
The present invention provides knotless suture anchor systems and devices for attaching soft tissue to bone. The systems and devices include suture anchors configured to engage and fasten sutures using set screws such that the locked sutures are free from frictional engagement with bone, screw threading, or internal walls of the anchors and set screws. Fastened sutures may also be re-tensioned by loosening a set screw to unfasten the sutures, adjusting the positioning of the sutures, and tightening the set screw to refasten the sutures. In some embodiments, the systems and devices enable the insertion of a suture anchor without preloading sutures, such that one or more sutures may be fastened to the suture anchor after implanting the suture anchor into a subject.
