Methods and devices for fixation of soft tissue to bone are provided. In one embodiment, a suture anchor is provided having an elongate cylindrical body with proximal and distal ends and an inner lumen extending therethrough. The elongate body can be configured so that upon partial insertion into a bone hole, it is securely anchored within the bone hole and a suture extending through the inner lumen is freely slidable. It can also configured so that, upon further insertion into the bone hole, at least a portion of the elongate body compresses to lock the suture within the inner lumen such that the suture is prevented from sliding. In another embodiment, a suture anchor is provided having arms that have an open position for receiving a suture therebetween, and a closed position in which the suture is retained but allowed to slide freely. |

1. A suture anchor, comprising:
an elongate substantially cylindrical body having a proximal portion with at least one bone-engaging surface feature formed on an external surface thereof, a flexible distal portion, and an inner lumen extending between a proximal end and a distal end of the elongate body; and a suture-engaging member monolithic with and positioned within the inner lumen of the elongate substantially cylindrical body configured to receive a suture there around, the elongate body being configured such that, upon insertion of the distal portion into a bone hole and engagement of at least one of the at least one bone-engaging surface features with the bone hole, a suture extending through the inner lumen and coupled to the suture engaging member is freely slidable, and the elongate body being further configured such that, upon further insertion into the bone hole, the distal portion of the elongate body compresses radially inward against the suture-engaging member to lock the suture within the inner lumen such that the suture is prevented from sliding. |
