Abstract

Background: In rotator cuff tears, the preoperative tear morphology and concomitant intra-articular/subacromial lesions may influence surgical prognosis and postoperative functional recovery. Objectives: To describe tear morphology in full-thickness rotator cuff tears and to assess associated lesions detected during shoulder arthroscopy. Materials and Methods: A retrospective–prospective, longitudinal, uncontrolled study was conducted in patients with full-thickness rotator cuff tears indicated for arthroscopic repair at Da Nang Hospital from October 2022 to July 2024. Results: Tears measuring 1–3 cm were most common (48.7%), whereas tears >5 cm were least frequent (12.8%). Crescent-shaped tears predominated (59.0%), approximately 4–5 times more frequent than other tear patterns. Tendon retraction was mainly grade I and grade II (46.2% each), while grade III retraction was uncommon (7.6%). Among associated lesions (labral tears, long head of biceps tendon tears, and subacromial impingement), subacromial impingement was the most frequent (30.8%). Conclusions: Thorough assessment of rotator cuff tear morphology and associated lesions is essential in arthroscopic management to guide selection of the most appropriate surgical technique.
