ONE-HANDED AND DOUBLE ROW METHODS FOR TISSUE FIXATION

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation, namely embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein. Other preferred embodiments of the present invention relate to multi-anchor constructs that may employ threaded implants exclusively, push-in implants exclusively, or a combination of threaded and push-in implants.
