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

Abstract

This study was conducted to analyze clinical outcomes after arthroscopic stabilization procedures in patients with shoulder instability and posttraumatic adhesive capsulitis. 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. 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. Arthroscopic stabilization provided satisfactory functional recovery and range of motion in patients with anterior instability and posttraumatic adhesive capsulitis. Level of evidence: IV.
