A method and device for knotless fixation of tissue. The method utilizes a push-in type anchor (for example, a self-punching anchor) and a suture chain that includes a loop or a plurality of loops. A first portion of the suture chain is secured to the tissue to be fixated. The suture chain is next secured to the push-in type anchor (for example, by passing the suture chain through an eyelet of the anchor). The anchor is then advanced along the suture chain to bring a tip of the anchor above a chosen loop or link of the suture chain. The tip of the anchor is pushed through the chosen loop so that the tip locks the chosen loop in place (for example, by capturing both sides of the link above a shoulder of the anchor). With the captured link, the anchor is advanced into a pilot hole or socket formed in the bone, and then the anchor is rotated within the hole or socket to reel in the suture chain and to tension, therefore, the suture chain.
