BACKGROUND: Neer and Foster's open inferior capsular shift to treat acquired cases of anteroinferior shoulder instability due to an overstretched and redundant capsule is described with good results. Recently, new arthroscopic techniques were described to manage this problem. PURPOSE: To assess the results of a new arthroscopic reinforced inferior capsular shift technique based on Neer and Foster's open inferior capsular shift. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: This new technique of arthroscopic inferior capsular shift was used to treat 108 patients with anteroinferior shoulder instability due to capsular redundancy as confirmed clinically and during arthroscopy. It reduces the size of the redundant capsular pouch and reinforces the thinned-out capsule. Intraoperatively, patients with associated labral tears (n = 25) and patients with open rotator intervals (n = 8) were excluded, and only 75 patients with pure capsular redundancy were included in this study. RESULTS: Patients were followed for a minimum of 7 years. All 75 patients had patulous and redundant capsules. Three patients (4.0%) had a redislocation after a significant trauma. The range of motion preoperatively was 168.1° ± 7.5° in forward elevation, 64.7° ± 7.9° in external rotation, and T5.0 ± T0.8 in internal rotation. Postoperatively, it was 167.2° ± 5.8° in forward elevation, 59.95° ± 4.9° in external rotation, and T7.1 ± T1.0 in internal rotation. The American Shoulder and Elbow Surgeons (ASES) (70.76 to 97.53; P < .001), Constant (90.02 to 99.24; P < .001), and University of California, Los Angeles (UCLA) (21.97 to 33.84; P < .001) scores demonstrated significant improvement postoperatively. CONCLUSION: This novel technique of arthroscopic capsular shift addresses the problem of capsular redundancy present in many cases of anteroinferior shoulder instability. It tries to achieve a capsular shift based on the principles of Neer. The long-term results are very good.
