<B>Background:</B> Intratendinous tendon suture is known as atraumatic tendon suture, because the blood supply at the tendon end is less interfered with. We have added this intratendinous tendon suture to the single-row rotator cuff repair. The purpose of this study was to evaluate the postoperative results of this suture technique.<BR><B>Methods:</B> Forty-one patients with rotator cuff tears had cuff repair with the single-row repair and augmentation by the intratendinous tendon suture. The average age of the patients was 62.5 years old. The size of rotator cuff tear was as follows, incomplete tear and small tear: 6 shoulders, medium tear: 21 shoulders, large tear: 14 shoulders. The loop-shaped No.2 HiFi<SUP>®</SUP> suture was passed through the rotator cuff at the muscle-tendon junction. The edge of HiFi<SUP>®</SUP> suture was passed inside the loop, and the rotator cuff was grasped by the loop suture. The HiFi<SUP>®</SUP> suture was pulled out from the tendon end, and then passed through the bone tunnel at the greater tuberosity. After the cuff end was fixed to the greater tuberosity by single-row repair, HiFi<SUP>®</SUP> suture was fixed at the lateral aspect of the greater tubeosity.<BR><B>Results:</B> At six months after the operation, the result was evaluated by MRI images with Sugaya's classification. Re-rupture (Type-IV) was detected in only three cases (7.3%).<BR><B>Conclusion:</B> This suture technique, adding the intratendinous tendon suture to the single-row repair, might decrease the re-rupture of the rotator cuff repair.
