Arthroscopic Bankart Repair with Subscapularis Augmentation in The Treatment of Recurrent Anterior Shoulder Instability with Bone Loss

Abstract

Background: In this study, we focused on the analysis of new published surgical technique in the management of recurrent anterior shoulder dislocation in presence of glenoid bone defect using traditional Bankart repair augmented with subscapularis tendon. Method: This prospective study was performed on 30 patients having recurrent anterior shoulder dislocation; these patients were managed between January 2016 and December 2018, Thirty-one shoulders in thirty-one patients had arthroscopic Bankart repair and subscapularis augmentation. One patient was lost to follow up; thirty patients with thirty shoulders were evaluated using American shoulder and elbow surgeons score, the percentage of glenoid bone defect was evaluated using PICO method. Results: 30 patients were followed for 22.03 Months range 16 – 24 Months. Only one patient had recurrent dislocation after significant trauma. The American Shoulder and Elbow Surgeon Score (ASES) shows significant improvement in score from Mean ± SD 13.27 ± 3.24 to 23.47 ± 3.14 after, function Mean ± SD from 6.23 ± 2.01 to 8.83 ± 0.75 and pain decrease from Mean ± SD 6.17 ± 1.53 to1.33 ± 0.80, with no significant functional changes in ROM even ER at 90 abduction Mean ± SD changes from 79.00 ± 9.95 to 77.33 ± 7.85 or ER at side Mean ± SD changes from 68.67 ± 18.14to 66.33 ± 15.31. Conclusion: The procedure of Bankart repair with Arthroscopic Subscapularis Augmentation (ASA) is an effective procedure in the management of recurrent anterior shoulder dislocation associated with GBD ≤ 25% with good results.
