title: Arthroscopic Bankart repair with knotless suture anchor for traumatic anterior shoulder instability: results of short-term follow-up.
abstract: OBJECTIVE
  To assess the clinical results of arthroscopic Bankart repair with the knotless suture anchor for traumatic recurrent anterior shoulder instability.
  
  
  METHODS
  A total of 47 patients with traumatic recurrent anterior shoulder instability and without severe glenoid bone defect who underwent arthroscopic Bankart repair with knotless suture anchors and were followed-up for longer than 2 years were included in the present study. The average age at surgery was 26 years (range, 16 to 49 years), with an average follow-up period of 28 months (range, 24 to 38 months).
  
  
  RESULTS
  Clinical score as evaluated by the modified Rowe score advanced from 31 points to 91 points. In all, 35 patients were scored as excellent and 6 as good; the success rate was 87% (41 of 47), and the recurrence rate was 6.4% (3 of 47). External rotation was reduced by 8 degrees at adduction and by 6 degrees at 90 degrees of abduction. Of 12 patients, 7 (58%) returned completely to collision sports at preinjury levels, and 2 of 12 (17%) returned at a lower level. We experienced anchor-related trouble in 3 cases. One was the backwardness of the anchor at 2 months after operation. Breakage of the anchor loop occurred during the procedures in 2 cases.
  
  
  CONCLUSIONS
  The clinical results of arthroscopic Bankart repair with knotless suture anchor were favorable; however, some pitfalls, such as the backwardness of the anchor and cutting of the anchor loop, were experienced. When using this anchor, its properties should be well recognized.
  
  
  METHODS
  Level IV, therapeutic case series.
