To recommend optimal surgical techniques in cases of remaining anterior instability after Bankart repair, according to the amount of remaning labrum.

Between December 1996 and April 1999, we experienced 27 pateints that have undergone arthroscopy for recurrent shoulder dislocation. They were followed over 1 year (1 year to 3 year 2 months) and classified into three groups: Group I (Arthroscopic Bankart repair by transglenoid technique); 9 cases, Group II (Arthroscopic Bankart repair by suture anchor); 11 cases, Group III (Arthroscopic Bankart repair by transglenoid technique with suture anchor); 7 cases.

A significant difference was found between Group I and Group III patients with poor or no remaining labrum, especially in teims of shoulder stability and range of motion recovery.

Arthroscopic Bankart repair by suture anchor in a shoulder that has good labrum produced a good result. However, in a shoulder with poor labrum, the combination method of transglenoid technique with suture anchor should be considered to reduce recurrency.
