Functional Outcome of Arthroscopic Bankart Repair with Knotless Suture Anchor: A Retrospective Observational Study

Abstract

Background: Soft tissue in the shoulder contributes to anterior shoulder instability that results in humeral head displacement from the glenoid fossa. Repair of Arthroscopic Bankart is considered as a broadly accepted method for restoring labrum to the glenoid rim. Our study's objective is to assess the clinical outcomes of Bankart repair by knotless suture anchors at medium-term follow-up. Aim: To study the functional outcomes of using knotless suture anchor for recurrent instability of anterior glenohumeral and perform the clinical assessment using Rowe score in patients at 6-week, 3-month, and 6-month intervals. Materials and Methods: In this prospective trial, patients undergoing arthroscopic Bankart repair with 2.8 mm knotless suture anchor (MINI-VIM PK®) were enrolled in the study. Patients were assessed for stability, movement, and function of shoulders using the Rowe scale at the baseline, 6-week, 3-month, and 6-month follow-up period planned for early efficacy measures. Results: The mean age of the subjects was 28.10±6.14. In this trial, the patients have been diagnosed with recurrent shoulder dislocation on the left side in 51(69.86%) patients and right side in 22(30.14%) patients. The Rowe score shows significant (p<0.0001) improvement from 44.73±1.64 to 95.62±18.33 at the 6-month follow-up period. Thus, provided better clinical outcomes and less movement of recurrent instability with knotless suture anchor. Conclusions: The knotless suture anchor showed reduced recurrence rates, improved post-operative shoulder motion, and increased stability without adding complexity to the procedure.
