OBJECTIVESTo introduce a new arthroscopic Bankart repair by vertical mattress suture with anchors, and to evaluate its clinical effectiveness.

METHODSA new arthroscopic Bankart repair by vertical mattress suture with anchors was performed, including to insert only 2 anchors at 3 o'clock and 5 o'clock position and make vertical mattress suture of labrum-ligament complex at 2, 4 and 6 o'clock of labrum, and to shift up the anterior-inferior capsule. Nine cases of anterior glenohumeral instability without severe glenoid bone defect were followed-up for an average period of 14 months (range from 6 to 26 months). The average surgery age was 28 years (range from 21 to 46 years).

RESULTSThe average surgery time was 51 min (40 - 75 min). Clinical scores as evaluated by the modified Rowe score advanced from 40 +/- 16 points to 92 +/- 19 points (75 - 94). There was no any recurrence and complication. External rotation was reduced by 5 degrees at 0 degrees adduction and by 3 degrees at 90 degrees of abduction.

CONCLUSIONSThe arthroscopic Bankart repair by vertical mattress suture with anchors for anteroinferior glenohumeral instability is favorable as an easy, short-time surgery with excellent clinical results in short-term follow-up.
