Discussion: (see rotator cuff repair menu)
- AP dimension is about 25 mm and the medial-lateral dimension is 14 mm;
- the more that a repair covers and secures tendon over the healing zone, the greater the chance for tendon-bone healing;

- Medialization of the supraspinatus tendon:
- indicated for situations in which the rotator cuff cannot be adequately mobilized;
- instead of reattachement of the cuff to greater tuberosity, the cuff is re-attached to a groove created on anatomic neck or on
humeral head;
- as noted by Liu J,et al (1998), about 1 cm of medialization may be acceptable but 17 mm of  supraspinatus medialization will
result in a significant reduction in the moment arm;
