Abstract

The double-row suture-bridge technique yields favorable outcomes in patients with full-thickness rotator cuff tears; however, postoperative shoulder function may still be influenced by preoperative tear characteristics. Objective: To analyze the association between tendon retraction and postoperative shoulder function, and to evaluate the effects of tear size and tear pattern on treatment outcomes. Materials and Methods: We conducted a longitudinal, non-controlled study with both retrospective and prospective components in patients with full-thickness rotator cuff tears undergoing arthroscopic repair at Da Nang Hospital from October 2022 to July 2024. Results: Retraction grades I and II were most common (46.2% each), whereas grade III retraction was uncommon (7.6%). Medium-sized tears (1–3 cm) accounted for the largest proportion (48.7%), while massive tears (>5 cm) were least frequent (12.8%). Crescent-shaped (C-shaped) tears were the most prevalent pattern (59.0%), approximately 4–5 times more common than other patterns. At 3 months postoperatively, shoulder function differed significantly according to tendon retraction grade (p = 0.001) and tear pattern (p = 0.03). No significant association was observed between tear size and postoperative recovery. Conclusion: Tendon retraction and tear pattern were associated with shoulder function at 3 months after arthroscopic rotator cuff repair using the double-row suture-bridge technique.
