Subacromial Impingement Syndrome:a Systematic Review Of Arthroscopic Versus Open Subacromial Decompression

Objective:To assess the clinical therapeutic effects of arthroscopic subacromial decompression versus open subacromial decompression in the treatment of subacromial impingement syndrome. Methods:Controlled trials on arthroscopic subacromial decompressionversus open acromioplasty in the treatment of subacromial impingement syndrome werecollected in different databases through computer search. There was no limitation for language, randomized controlled trials or blinded studies. At last, the meta-analysis was conducted by using RevMan5.0 software. Results:Four randomized controlled trials and six non-randomized controlled trials were included in this study, involving 583 patients with subacromial impingement syndrome. The results of meta-analysis prompted that as to the hospital inpatient days and time until return to work, the group of arthroscopic subacromial decompression was shorter than open subacromial decompression. However, as to the postoperative shoulder functional scores, the operative time, patient’s satisfaction, and the rate of excellent and good results of postoperative UCLAs, there were no significant statistical differences between two groups. Conclusion: Due to the certain limitations and deficiencies of the quantity and quality in the included trials, there must still need large-sample, multi-centered, high-quality randomized controlled trials to confirm these results.
