Abstract

Background: Latest studies have shown effective clinical outcomes after arthroscopic Bankart repair (ABR) but have shown some risk factors for re-dislocation after surgery. We assessed whether patients are at a risk for re-dislocation during the first year after ABR, examined the recurrence rate after ABR, and sought to recognize new risk factors.
Materials and Methods: We performed ABR utilizing bioabsorbable suture anchors in 51 consecutive shoulders (50 patients) with traumatic anterior shoulder instability. Average patient age was 26.5 (range, 15–40) years. We assessed re-dislocation after ABR using patient telephone interviews (follow-up rate, 100%) and correlated re-dislocation with several risk factors.
Results: Re-dislocation after ABR occurred in five shoulders (9.8%), of which 4 sustained re-injuries within the first year with the arm elevated at 90° and externally rotated at 90°. Of the remaining 46 shoulders without re-dislocation, 4 had re-injury under the same conditions within the first year. Consequently, re-injury within the first year was a risk for re-dislocation after ABR (P < 0.001, chi-squared test). Using multivariate analysis, large Hill-Sachs lesions (odds ratio, 6.75; 95% CI, 1.35-64.5) and <4 suture anchors (odds ratio, 9.45; 95% CI, 1.88-72.5) were significant risk factors for re-dislocation after ABR.
Conclusion: The recurrence rate after ABR was not associated with the time elapsed and that repair strategies should augment the large humeral bone defect and use >3 anchors during ABR.
