Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with splices and loops that are pre-loaded onto modified knotless anchors (for example, swivel and/or screw-in suture anchors and/or push-in suture anchors with a distal eyelet) to position the self-locking, adjustable construct at the repair site. The systems allow for knotless tensioning of the tissue after the knotless anchors have been implanted.
