Therefore, the purpose of this study was to evaluate and compare short-term clinical and radiological results of three surgical treatment options for these patients.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A multicenter randomized trial was conducted. Sixty-nine patients were randomly assigned to receive 1. subacromial decompression (Group SAD), 2. debridement of calcifications (Group D), or 3. debridement of calcifications with SAD (Group D\u2009+\u2009SAD). Stringent inclusion and exclusion criteria were used. The primary outcome was an improvement in VAS for pain (pVAS) 6 months postoperatively. Secondary outcomes were an improvement in pVAS 6 weeks postoperatively, functional outcomes (CMS, DASH, ASES), radiological outcome, additional treatments, and complications.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The improvement in pVAS was significant in all groups (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and did not differ between the groups after 6 months. Six weeks postoperatively, the improvement in pVAS was significantly (<jats:italic>p<\/jats:italic>\u2009=\u20090.03) less in Group SAD compared to Group D\u2009+\u2009SAD (16.5\u00a0mm, SD 19.3\u00a0mm vs 33.1\u00a0mm, SD 19.7\u00a0mm, respectively). The mean size of calcifications decreased significantly in all groups (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001). In Group SAD, the size of the calcifications decreased less (<jats:italic>p<\/jats:italic>\u2009=\u20090.04) compared to Group D and Group D\u2009+\u2009SAD after 6 weeks. Group SAD received more additional treatments (<jats:italic>p<\/jats:italic>\u2009=\u20090.003) compared to Group D\u2009+\u2009SAD (9 vs 1), which were mainly subacromial cortisone injections.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>All patient groups showed significant pain relief and an improvement in shoulder function 6 months after surgery. However, patients in Group SAD showed inferior pain relief and less\u00a0improvement in DASH score after 6 weeks. Furthermore, this group required more postoperative additional treatments. No significant differences in clinical and radiological outcomes were observed between patients in Group D compared to Group D\u2009+\u2009SAD. Therefore, an arthroscopic debridement without subacromial decompression seems to be advisable for patients with therapy-resistant calcifying tendinitis of the shoulder.<\/jats:p>\n                <jats:p><jats:italic>Level of evidence <\/jats:italic>2, Open-Label Randomized Clinical Trial.<\/jats:p>\n                <jats:p><jats:italic>IRB<\/jats:italic> METC Zuyderland MC.
