A knotless anchor for attachment of tissue to bone includes a rigid anchor body and a suture extending there from. The suture is hollow and includes a fixed limb portion secured to the rigid anchor body. A soft suture tunnel extends in a longitudinal direction through the fixed limb portion of the suture. A free suture limb is passed through the tissue, back to the anchor, and through the soft suture tunnel, thereby creating a closable suture loop around the tissue. Tension applied to the free suture limb closes the suture loop, and approximates the tissue to the anchor body. When the anchor is deployed in a bone hole, external features of the anchor body grip the walls of the bone hole and simultaneously compress the suture, thereby preventing tissue pull-out. Anchor assemblies and methods of tissue fixation are also disclosed. 1. A knotless anchor for attaching a tissue to a bone , the knotless anchor comprising:a rigid anchor body comprising a proximal end, a distal end, and at least one bone locking feature for engaging an internal wall of a bone hole; anda hollow suture comprising a suture fixed limb secure to the anchor body, a suture free limb, and a length of suture extending there between wherein the suture fixed limb comprises a suture entry port, a suture exit port, and a longitudinally-disposed suture tunnel extending from the suture entry port to the suture exit port.2. The knotless anchor of wherein the at least one bone locking feature is selected from the group consisting of a barb claim 1 , ridge claim 1 , thread claim 1 , and rib.3. The knotless anchor of wherein the suture fixed limb is secure to the anchor body via bonding claim 1 , ultrasonic welding claim 1 , ultrasonic staking claim 1 , heat staking claim 1 , ultrasonic molding claim 1 , or injection molding the anchor body to the hollow suture.4. The knotless anchor of comprising a maximum number of suture limbs extending from the bone hole claim 1 , wherein the maximum number of suture limbs ...
