Abstract

Background: The soft tissue in the shoulder plays a significant role in anterior shoulder instability, leading to humeral head displacement from the glenoid fossa. Arthroscopic Bankart repair is a widely accepted method to restore the labrum to the joint rim. This study aims to evaluate the clinical outcomes of Bankart repair by knotless suture anchors at medium-term follow-up, assess the functional outcomes of the knotless suture anchor method for recurrent anterior glenohumeral instability, and conduct clinical assessment using the Rowe score at 6-week, 3-month, 6-month, and 12-month intervals in patients.

Methods: In this retrospective study, patients who underwent arthroscopic Bankart repair using a 2.8 mm knotless suture anchor (MINI-VIM PK® ) were enrolled. They were assessed for shoulder stability, range of motion (ROM), and functional outcomes using the Rowe scale at the baseline, 6-week, 3-month, 6-month, and 12-month follow-up intervals as part of the planned early efficacy measures. All the statistical analyses were performed using SPSS software.

Results: The mean age of the subjects was 28.10 ± 6.14. In this trial, 51 patients (69.86%) were diagnosed with recurrent shoulder dislocation on the left side, and 22 patients (30.14%) on the right side. The Rowe score demonstrated a significant improvement (P < 0.0001), increasing from 44.73 ± 1.64 to 95.62 ± 18.33 at the 12-month follow-up period. This indicated better clinical outcomes and reduced recurrence of instability with the use of knotless suture anchors.

Conclusion: The use of knotless suture anchors demonstrated reduced recurrence rates, improved post-operative shoulder motion, and increased stability without adding complexity to the procedure.
