Reflected by the high retear rates, the preoperative selection of patients suitable for surgery or conservative treatment, which often yields comparable results, remains difficult. Using contrast\u2010enhanced ultrasound (CEUS), it is possible to quantify the SSP muscle perfusion as a surrogate parameter for its vitality and healing capabilities. In this study, we enrolled 20 patients who underwent an SSP repair for a preoperative and two postoperative (6 months and 1 year) clinical and sonographic exams including CEUS. Along with functional improvement (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, Constant score), we found a significant increase in CEUS\u2010assessed muscle perfusion after tendon repair (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Furthermore, weak preoperative muscle perfusion was associated with a higher risk of a retear (<jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u20090.045) and a moderate trend toward\u00a0lower postoperative shoulder function that did not reach significance (<jats:italic>r<\/jats:italic>\u2009=\u20090.435; <jats:italic>p<\/jats:italic>\u2009=\u20090.055, DASH score). If confirmed in larger studies, CEUS might be a valuable additional diagnostic method for a precise selection of patients who most likely profit from a tendon repair and those who can be treated conservatively with an equally good outcome.<\/jats:p>","DOI":"10.1002\/jor.25349","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T13:33:27Z","timestamp":1650720807000},"page":"426-435","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["CEUS\u2010assessed
