Anti-Backup Suture Anchor

摘要

Devices and methods are provided herein that generally involve suture anchors having one or more anti-backup features configured to resist or prevent backward movement of a suture that is pulled through the suture anchor. In some embodiments, the suture anchor can be configured to permit a suture to slide freely in one direction but resist or prevent suture movement in the opposite direction. For example, cleats can be rotatably mounted within the suture anchor, can project radially outward from an exterior sidewall of the suture anchor, or can project circumferentially from sidewalls of one or more channels formed in the suture anchor's exterior surface.

1. A method for anchoring tissue to bone, comprising:
inserting a suture anchor into bone; applying tension to free ends of a suture coupled to the suture anchor such that the suture slides around the suture anchor and pulls soft tissue coupled to a looped end of the suture toward the suture anchor; wherein the suture anchor includes at least one suture-engaging element that allows the suture to slide in a first direction relative to the suture anchor, but that engages and prevents the suture from sliding in a second opposite direction relative to the suture anchor to thereby lock the suture relative to the suture anchor and thereby secure the soft tissue to the bone.
