Background: There are many reports of short term good results of Arthroscopic Subacromial Decompression(ASD), but few long term results have been published. Recently, arthroscopic rotator cuff repair (ARCR) has been addressed as a useful procedure for partial-thickness rotator cuff tear (PRCT).
The aim of this study was to investigate clinical results of arthroscopic subacromial decompression(ASD) for bursal side partial-thickness rotator cuff tear(PTRCT).
Methods: Thirty three shoulders of 31 patients were included in this study (Ellman's grade I b; 20 shoulders, grade II b; 10 shoulders, grade III b; 3 shoulders). Articular side PTRCT, full-thickness RCT, and calcific tendinitis were excluded from this study. We evaluated clinical outcome according to the Japanese Orthopaedic Assosiation(JOA) score.
Results: The average of follow-up term was 24 months (range 6 to 96 months). The average of age at the time of operation was 60 years (range 47 to 76). The average JOA score increased from 68.7 points (range 46 to 85 ) preoperatively to 96.1 points (range 82 to 100) postoperatively. One patient(3.0%)required rotator cuff repair.
Discussion: The good result was obtained by surgical debridement and conformity of the 2nd shoulder joint. Postoperative MRI showed a satisfying result except for one case which was required rotator cuff repair.
It seems that ASD is a simple and less invasive surgery, and it is one of the optional procedures for bursal side partial-thickness rotator cuff tear which has resisted conservative treatment.
Moreover, ASD was usually performed for ARCR, thus it was suggested that it is important to treat the conformity of the 2nd shoulder joint.
