Nine matched pairs of cadaver shoulders were used. Full-thickness tears were induced by detaching the supraspinatus tendon from the greater tuberosity. Single-row repairs were performed with either type I (Opus Magnum PI; ArthroCare, Austin, Texas) or type II (ReelX STT; Stryker, Mahwah, New Jersey) knotless suture anchors. The repaired tendon was cycled from 10 to 90 N for 500 cycles, followed by load to failure. Gap formation was measured at 5, 100, 200, 300, 400, and 500 cycles with a video digitizing system. Anchor type or location (anterior or posterior) had no effect on gap formation during cyclic loading regardless of position (anterior,\n            <jats:italic>P<\/jats:italic>\n            =.385; posterior,\n            <jats:italic>P<\/jats:italic>\n            =.389). Maximum load to failure was significantly greater (\n            <jats:italic>P<\/jats:italic>\n            =.018) for repairs performed with type II anchors (288\u00b162 N) compared with type I anchors (179\u00b139 N). Primary failure modes were anchor pullout and tendon tearing for type II anchors and suture slippage through the anchor for type I anchors.\n          <\/jats:p>\n          <jats:p>The internal ratcheting suture-retention mechanism of type II anchors may have helped this anchor outperform the suture-cinching mechanism of type I anchors by supporting significantly higher loads before failure and minimizing suture slippage, potentially leading to stronger repairs clinically.<\/jats:p>","DOI":"10.3928\/01477447-20130724-19","type":"journal-article","created":{"date-parts":[[2014,8,19]],"date-time":"2014-08-19T22:07:02Z","timestamp":1408486022000},"source":"Crossref","is-referenced-by-count":7,"title":["Knotless Single-row Rotator Cuff Repair: A Comparative Biomechanical Study of 2 Knotless Suture Anchors"],"prefix":"10.3928","volume":"36","author":[{"given":"Chad","family":"Efird","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaun","family":"Traub","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Todd","family":"Baldini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dana","family":"Rioux-Forker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey P.","family":"Spalazzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Twana","family":"Davisson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Hawkins","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"McCarty","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-193306000-00007"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.46B2.314"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198710000-00007"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199501000-00002"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1058-2746(99)90148-9"},{"issue":"321","key":"e_1_3_2_7_2","first-page":"178","article-title":"Non-operative treatment of rotator cuff tears","author":"Hawkins RH","year":"1995","unstructured":"Hawkins RH, Dunlop R.
