Outcomes of arthroscopic Bankart repair (ABR) for anterior shoulder instability using two knotless suture anchors fixation.

Objectives: The purpose of this study is to evaluate the short term outcomes of isolated Arthroscopic Bankart Repair (ABR) using knotless suture anchor technique, in young and middle aged patients with post traumatic Anterior Shoulder Instability (ASI). Study Design: Prospective Observational Study. Setting: Sports Units of Hayatabad Medical Complex, Peshawar. Period: January 2018 to December 2020. Material & Methods: 32 patients were included in this study, all of them were male, and who had traumatic anterior shoulder dislocation and underwent Arthroscopic Bankart Repair (ABR), with at least 2 years follow-up and minimum of 4 months of physiotherapy postoperatively. Sample size was calculated through non-probability consecutive sampling technique. Recurrent instability, postoperative glenohumeral osteoarthritis, post-surgical complications and subjective scores (Simple Shoulder Test [SST], American Shoulder and Elbow Surgeon [ASES] and Rowe scores) were evaluated. Results: Among the 32 participants, five patients (15.6%) experienced at least one episode of redislocation, eight patients (25%) had moderate to severe glenohumeral-osteoarthritis. The overall satisfaction rate was 76% with ASES, SST and Rowe scores of 82%, 9% and 79% respectively. One patient (3.12%) had wound infection. Conclusion: Isolated Arthroscopic Bankart Repair (ABR) using knotless suture anchor fixation  for anterior shoulder instability followed by physiotherapy has excellent short term outcome in term of low post-surgical complication rate, high patient satisfaction, ability to joint work back and improved subjective scores, although high rate of postoperative glenohum eral osteoarthritis is disappointing necessitating further studies on the matter.
