- Single Row Technique:
      - one row of anchors is placed in the greater tuberosity usually lateral to the rotator cuff footprint

- Double Row Technique:
      - one row of anchors are placed at the articular margin and the second row is placed lateral to the footprint
- transosseous equivalent
- one row of anchors is placed at the articular margin then laid down on top of the rotator cuff and secured
to a lateral row of anchors;
- differs from double row in that one set of common sutures is shared between the two rows of anchors and
it acts to compress the rotator cuff on the native footprint rather than “spot weld”.

- Author's Preferred Technique:
    - uses a shuttle passer, Mitek Helix, and Versalok anchor;
- Helix anchor is placed into the medial footprint;
- use a suture passer to shuttle one blue suture 2 cm superior and about 15 mm anterior to the anchor (shuttle out the anterior cannula).
- use a suture passer to shuttle one green suture 2 cm superior and about 15 mm posterior to the anchor. (shuttle out the anterior cannula)
- with green and blue sutures passed out of the anterior cannula, tie them together using an anchor knot;
- pull the green and blue sutures that remain out of the lateral portal (ensure that the knotted end is tight against the cuff);
- tension on the sutures shoud compress the footprint;
- use the shuttle passer to pass both the green and blue sutures (together) thru the cuff immediately superior to anchor about 5 mm superior to
the previous knotted repair (pull out the anterior portal);
- use the shuttle passer to pass the two sutures thru the inferior aspect of the foot print and out the lateral portal;
- tension and lock using a Versalok as a lateral row;
- as the cuff is tensioned, the surgeon should visualize tensioning of the sutures without lateralization of the cuff;

- Alternative Techniques:
- "belt and suspenders techique" - when the belt tightens, the suspenders tighten too.
- involves insertion of mitke helix anchor at the foot print;
- one green and one blue suture are passed upwards through the cuff tear (expresso suture passer);
- these are brought out the lateral cannula tied together, and then the un-tied green and blue sutures are tensioned which brings the knot over cuff tear (this is the belt or the transverse limb);
- remaining untied sutures are brought up through the cuff on either side of the transverse limb, and are then passed through a versalock anchor which forms the lateral sided fixation; (these form the suspenders)
- when the versalok is tensioned, not only are the suspenders tensioned but also the belt is tensioned;
