All articles describing the current understanding of the aforementioned therapies were reviewed. Studies were excluded if they were non-English or reported incomplete results.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Matrix metalloproteinases (MMP\u2019s) are fundamental to the healing process after rotator cuff tears through a delicate balance of various proteases that can be modulated by doxycycline through inhibition. While testosterone has shown to induce replication and differentiation of the tendon stem-cells, estrogen agonists have been shown to decrease inflammation and muscle atrophy. Though growth hormone being associated with elevated collagen synthesis and decreased anoxic damage when present, clinical studies have shown inconclusive and adverse effects on rotator cuff healing. Patients with Vitamin D deficiency have shown to have increased fatty infiltration in rotator cuff muscle while Vitamin C functions as an antioxidant that increases collagen and fibroblast proliferation.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n As manipulation of pharmacologic factors shows potential for enhancing healing following RCRs, future studies are needed to establish a viable augmentation strategy to improve patient outcomes<\/jats:p>\n <\/jats:sec>","DOI":"10.52965\/001c.37782","type":"journal-article","created":{"date-parts":[[2022,9,3]],"date-time":"2022-09-03T23:43:11Z","timestamp":1662248591000},"source":"Crossref","is-referenced-by-count":11,"title":["Pharmacologic Enhancement of Rotator Cuff Repair: A Narrative Review"],"prefix":"10.52965","volume":"14","author":[{"given":"Maksim","family":"Vaysman","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03cc0mm23","id-type":"ROR","asserted-by":"publisher"}],"name":"Nassau University Medical Center","department":["Orthopedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Alben","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery, Nassau University Medical Center; Osteopathic Medicine, New York Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Todd","sequence":"additional","affiliation":[{"name":"Orthopedic Surgery, Nassau University Medical Center; Osteopathic Medicine, Des Moines College of Osteopathic Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Ruotolo","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03cc0mm23","id-type":"ROR","asserted-by":"publisher"}],"name":"Nassau University Medical Center","department":["Orthopedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"30777","published-online":{"date-parts":[[2022,9,4]]},"reference":[{"issue":"5","key":"ref1","doi-asserted-by":"publisher","first-page":"1223","DOI":"10.1177\/0363546503262200","article-title":"Matrix metalloproteinase and tissue inhibitor of matrix metalloproteinase mRNA levels are specifically altered in torn rotator cuff tendons","volume":"32","author":"Ian K.
