[Arthroscopic Bankart lesion repair by double-row vertical mattress suture with anchors for anteroinferior glenohumeral instability].

Objectives To introduce a new arthroscopic Bankart repair by vertical mattress suture with anchors,and to evaluate its clinical effectiveness.Methods 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).Results 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° at 0° adduction and by 3° at 90° of abduction.Conclusions 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.
