functional outcome of arthroscopic bankart repair with knotless suture anchor: a retrospective observational study

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.
