There is also a frequency dependence and time dependence to this finding, with more frequent injections and with administration of injections closer to the time of surgery both independently associated with higher revision RCR rates. Presently, on the basis of this retrospective database study, orthopaedic surgeons should exercise due caution regarding shoulder injections in patients whom they are considering to be surgical candidates for RCR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level III, therapeutic study.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2018.10.116","type":"journal-article","created":{"date-parts":[[2019,2,4]],"date-time":"2019-02-04T18:54:29Z","timestamp":1549306469000},"page":"717-724","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":48,"title":["Injections Prior to Rotator Cuff Repair Are Associated With Increased Rotator Cuff Revision Rates"],"prefix":"10.1002","volume":"35","author":[{"given":"Alexander E.","family":"Weber","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery University of Southern California Los Angeles California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas A.","family":"Trasolini","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery University of Southern California Los Angeles California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik N.","family":"Mayer","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery University of Southern California Los Angeles California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Essilfie","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery University of Southern California Los Angeles California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"C.
