Background: Ultrasound imaging has been widely used as a diagnostic tool for rotator cuff tears. Several studies have explored the changes in rotator cuff tendon morphology after arthroscopic cuff repair, however none have addressed the fate of sutures. The aim of this study was to determine: (1) if the sutures migrate through the tendon during the postoperative healing period in patients who have had arthroscopic rotator cuff repair, (2) if the sutures do migrate, the time point at which it does and, (3) if the quality of the tendon, in terms of tendon stiffness, modulus of elasticity, bursal thickness and anatomical footprint, affects suture migration.
