A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.
