Clinical outcomes of arthroscopic stabilization procedures in patients with shoulder dislocation combined with posttraumatic adhesive capsulitis

Background: This study was conducted to analyze clinical outcomes after arthroscopic stabilization procedures in patients with shoulder instability and posttraumatic adhesive capsulitis. Methods: Patients who underwent arthroscopic Bankart repair between 2019 and 2022 with limitation of forward flexion <120°, external rotation <30°, and internal rotation below L3 were included. Demographic data, arthroscopic findings, visual analog scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score were evaluated. Results: Nineteen (4.3%) of 442 patients were included in the study with a mean follow-up of 33.7±2.8 months. The mean age was 32.8±1.9 years, with a mean time of 6.6±1.8 months from the last episode of instability. At final follow-up, 17 of 19 patients (89.5%) recovered full ranges of motion. Forward flexion improved from 112.2°±9.4° to 170.8°±2.1° (P<0.001), internal rotation from 2.3±0.4 to 7.2±0.8 (P=0.001), and external rotation from 23.2°±1.3° to 61.6°±2.8° (P=0.019). The mean VAS score decreased from 3.5±0.5 to 0.4±0.2 (P<0.001). The ASES score improved from 71.7±2.4 to 92.7±2.2 (P<0.001), and the Rowe score increased from 71.5±3.2 to 97.4±1.0 (P<0.001). No complications or revision surgeries occurred. Conclusions: Arthroscopic stabilization provided satisfactory functional recovery and range of motion in patients with anterior instability and posttraumatic adhesive capsulitis. Level of evidence: IV.
