[Purpose]The purpose of this study was to evaluate the arthroscopic findings and postoperative results between the staple capsulorraphy and the suture anchor procedure for an anterior instability of the shoulder.
[Materials and methods]Fifty five shoulders of 55 patients,41 males and 14 females, were examined. The age at operation ranged from 13 to 33, average 24.5 years old. Bankart's lesion was classified into 4 types using Kurokawa's arthroscopic classifications.35 cases (type1=15, type2n=15, type2a=3, type3n=1 and type3a=1) were treated by staple capsulorraphy and 20 cases (type1=15, type2n=2, type2a=2, type3n=1) were treated by suture anchor procedure.
[Results]After the staple capsulorraphy, the apprehension sign remained in 9 cases (typte1=3, type2n=4, type2a=1 and type3a=1) and subluxation recurred in 5 cases(typte1=1, type2n=3 and type3a=1). On the other hand, after suture anchor procedures, the apprehension sign was remained in only 2 cases (typte1=2) and a subluxation did not occur in any case.
[Conclusion]Arthroscopic Bankart's repair using a suture anchor resulted in better recovery than that of the staple capsulorraphy in patients with anterior instability of the shoulder.
