Knotless, adjustable anchor systems that allow for knotless tensioning of tissue (such as the rotator cuff) after anchor implantation. The knotless, adjustable anchor system includes knotless anchors (for example, swivel and/or screw-in suture anchors and/or push-in suture anchors) that are modified to carry a self-locking, adjustable construct (for example, a suture assembly with a spliced suture loop) and to position the self-locking, adjustable construct at the repair site. The system allows for knotless tensioning of the tissue after the knotless anchors have been implanted. The medial row anchors are implanted and passed through tissue in a similar fashion as the current Corkscrew® or SwiveLock® C anchors are. The lateral row anchors are similar to a knotless SutureTak® but modified to accommodate a larger suture to hold a larger load. The suture is interconnected to the medial row and returned back to the lateral row for loading into the splice.
