PURPOSE: The purpose of this study was to evaluate the clinical result of modified Bankart operation repairing the Bankart lesion with capsular shifting using suture anchor in traumatic recurrent anterior dislocation of shoulder joint MATERIALS AND METHODS: All of the cases were treated with modified Bankart operation. The inferior and superior capsular flaps were advanced to the anterior aspect of glenoid neck and fixed with three suture anchors in 30 degrees abduction and external rotation of shoulder joint. Especially the inferior 1/3 capsular flap was sutured over the superior 2/3 capsular flap. We used the grading system of Rowe and Zarins as measuring function, pain, stability, range of motion of shoulder joint. RESULT: The clinical results were excellent in 80%, good in 20%. The mean loss of motion at follow up study was 2% of flexion and 7% of external rotation. CONCLUSION: This operative technique is useful in repairing the Bankart lesion and gaining adequate capsular tension. And the using of suture anchor could save the operation time.
