The embodiments provided for herein relate to apparatus and methods for securing tissue to bone using a suture anchoring system that provides enhanced tactile feedback and does not require tying a suture knot. In each embodiment, a surgeon can individually tension the free ends of the suture to fine-tune the placement of the tissue with respect to the bone, and then secure the suture without tying a knot. In several embodiments, the device may be transformed between locked and unlocked suture states, thereby allowing further fine-tuning of the tension in the suture. In other embodiments, the device may permit unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction.
