23 October 2018	New citation required and conclusions have changed	Review updated; four new trials included and eight in total
22 October 2018	New search has been performed	The original review, 'Surgery for rotator cuff disease', published in 2007 was split into three reviews upon updating: this review, 'Subacromial decompression for rotator cuff disease', and two pending updates, 'Surgery for full‐thickness rotator cuff tears', and 'Surgery for calcific rotator cuff tendinopathy'. We excluded the comparison of one type of surgical technique to another in this update. We included four new trials in this update: Beard 2018; Farfaras 2016; Ketola 2009; Paavola 2018 in addition to three trials included in the 2007 version (Brox 1993; Haahr 2005; Rahme 1998). An additional trial, translated from German was excluded in the 2007 version of the review as it was unclear that it was an RCT, but was included in this update after the author confirmed it was an RCT (Peters 1997).
