Using the simplified placement system and method for a tissue graft anchor of the present invention, 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 of the present invention allow for the placement of small diameter knotless anchors. For example, the implant placement system may include a cannulated tensioning device having disposed therein an elongate member of a suitably elastic metallic or polymeric material, such as nitinol, that includes at its distal end a loop of material suitable for suture retention. The implant placement system may further include high tensile strength knotless anchors provided with internal drive features that coordinate with torque-transmitting features unique to the driver devices of the present invention.
