ABSTRACT
<p><b>OBJECTIVES</b>To introduce a new arthroscopic Bankart repair by vertical mattress suture with anchors, and to evaluate its clinical effectiveness.</p><p><b>METHODS</b>A 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).</p><p><b>RESULTS</b>The 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.</p><p><b>CONCLUSIONS</b>The 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.</p>
