A single-row repair with two suture anchors was conducted in group 1 and a double-row repair with four suture anchors in group 2. A total of ten intact contralateral shoulder joints was used as a control group. Biomechanical testing was performed immediately post-operatively and at four and eight weeks, and histological analysis at four and eight weeks. <\/jats:p><jats:p> The mean load to failure in group 2 animals was greater than in group 1, but both groups remained lower than the control group at all intervals. Histological analysis showed similar healing properties at four and eight weeks in both groups, but a significantly larger number of healed tendon-bone interfaces were identified in group 2 than in group 1 at eight weeks (p &lt; 0.012). <\/jats:p><jats:p> The ultimate load to failure increased with the number of suture anchors used immediately post-operatively, and at four and eight weeks. The increased load to failure at eight weeks seemed to be related to the increase in the surface area of healed tendon-to-bone in the double-row repair group. <\/jats:p>","DOI":"10.1302\/0301-620x.90b10.20862","type":"journal-article","created":{"date-parts":[[2008,9,30]],"date-time":"2008-09-30T21:24:21Z","timestamp":1222809861000},"page":"1386-1391","source":"Crossref","is-referenced-by-count":49,"title":["A comparison of single-<i>versus<\/i> double-row suture anchor techniques in a simulated repair of the rotator cuff"],"prefix":"10.1302","volume":"90-B","author":[{"given":"M.","family":"Ozbaydar","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Okmeydani Teaching Hospital, 34387, Okmeydani, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Elhassan","sequence":"additional","affiliation":[{"name":"Mayo Clinic, 200 First Street, Rochester, Minnesota 55905, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Esenyel","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Vakif Gureba Teaching Hospital, 34093, Fatih, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Atalar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Istanbul University, Istanbul School of Medicine, 34390, Capa, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Bozdag","sequence":"additional","affiliation":[{"name":"Department of Medical Engineering, Istanbul Technical University, 34437, G\u00fcss\u00fcssuyu, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Sunbuloglu","sequence":"additional","affiliation":[{"name":"Department of Medical Engineering, Istanbul Technical University, 34437, G\u00fcss\u00fcssuyu, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Kopuz","sequence":"additional","affiliation":[{"name":"Department of Pathology, Istanbul University, Cerrahpasa Medical Faculty, 34098, Fatih, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Demirhan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Istanbul University, Istanbul School of Medicine, 34390, Capa, Istanbul, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","reference":[{"key":"R1","doi-asserted-by":"crossref","unstructured":"Curtis AS, Burbank KM, Tierney JJ, Scheller AD, Curran AR.
