Tendon trap technique for rotator cuff repair

Abstract

Strangulation around cuff tissue is a possible cause of retear after rotator cuff repair. Therefore, tendon healing ideally requires changes in suture tension over the cuff tissue in accord with rotator cuff muscle activity. The authors present a type of fixation that mimics the mechanism of the Chinese finger trap. The devised knot-free tendon trap technique resembles the double-pulley-suture bridge technique, but all suture limbs share the tension evenly and respond synchronized to the cuff tendon. The technique provides simple biologic repairs of rotator cuff tears.
