Arthroscopic Revision Bankart for Recurrent Anterior Shoulder Dislocation : Contributing Factor Analysis and a Case Report

Objectives: Recurrent shoulder dislocation after arthroscopic Bankart repair (ABR) is still a matter of discussion. The recurrence rate varies between four to fourteen percent in the general population. Re-injury timing, large anatomical defect, and anchor techniques are the factors contributing to re-dislocation after ABR, yet there was still no consensual algorithm for Bankart revision. Case presentation: We presented a case of 27 years old woman with recurrent anterior dislocation after seven years of arthroscopic Bankart repair. Seven years ago, we did Bankart repair using a 2.8 mm fiber-wire anchor (FASTak® (Arthrex, Karsfield Germany)). Now we decided to do arthroscopic revision using all suture anchor technique (Y-Knot® Flex All-Suture Anchor, 1.3mm – One strand of #2 Hi-Fi® (Conmed, New York)). Results: From preoperative and intraoperative assessment, we found that the mechanism of injury, Hill’s-Sachs lesion, Bankart lesion and the number of anchors contributed to re-dislocation. Four months postoperative follow up showed that the patient could gain a normal range of movement. No early or late complications were observed. Conclusion: The success of arthroscopic Bankart repair greatly depended on the preoperative assessment. The arthroscopic revision will do many benefits to the patient since it is less invasive and not compromising the post-operative range of motion of the shoulder.
