However, which materials yield the strongest constructs remains undetermined. Purposes: We sought to investigate whether SCR with polytetrafluoroethylene (PTFE) or human dermal allograft (HDA), 2 or 3 glenoid anchors, and suture or minitape resulted in better failure load properties at the patch-glenoid interface. Methods: We conducted a biomechanical study in 30 glenoid-sided SCR repairs in Sawbones models divided into 5 groups. Each was pulled to failure to assess mode of failure, peak load (N), stiffness (N\/mm), yield load (N), peak energy (N\u2009m), and ultimate energy (N\u2009m). The 5 groups were as follows: group 1\u2014PTFE, 2 anchors, and suture; group 2\u2014PTFE, 2 anchors, and minitape; group 3\u2014HDA, 2 anchors, and suture; group 4\u2014HDA, 2 anchors, and minitape; group 5\u2014PTFE, 3 anchors, and minitape. Results: Repairs failed by button-holing of suture\/minitape. Group 5 had greater peak load, stiffness, yield load, and peak energy (384 \u00b1 62 N; 24 \u00b1 3 N\/mm; 343 \u00b1 42 N; 4 \u00b1 2 N\u2009m) than group 3 (226 \u00b1 67 N; 16 \u00b1 4 N\/mm; 194 \u00b1 74 N; 2 \u00b1 1 N\u2009m) or group 4 (274 \u00b1 62 N; 17 \u00b1 4 N\/mm; 244 \u00b1 50 N; 2 \u00b1 1 N\u2009m) and greater ultimate energy (8 \u00b1 3 N\u2009m) than all other groups. Conclusions: This biomechanical study of SCR repairs in Sawbones models found that yield load was greater in PTFE than HDA, 3 anchors were better than 2, and minitape was no better than suture.<\/jats:p>","DOI":"10.1177\/15563316221114135","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T05:23:46Z","timestamp":1658985826000},"page":"44-52","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Biomechanical Comparison of Synthetic Polytetrafluoroethylene (PTFE) vs Human Dermal Allograft (HDA), 2 vs 3 Glenoid Anchors, and Suture vs Minitape in Superior Capsule Reconstruction"],"prefix":"10.1177","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0106-3129","authenticated-orcid":false,"given":"Ryan S.","family":"Ting","sequence":"first","affiliation":[{"name":"University of New South Wales, Sydney, NSW, Australia"},{"name":"Orthopaedic Research Institute, Saint George Hospital Campus, University of New South Wales, Sydney, NSW, Australia"},{"name":"South Western Sydney Clinical School, University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allen A.","family":"Guo","sequence":"additional","affiliation":[{"name":"University of New South Wales, Sydney, NSW, Australia"},{"name":"Orthopaedic Research Institute, Saint George Hospital Campus, University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5423-9530","authenticated-orcid":false,"given":"Ron","family":"Rosenthal","sequence":"additional","affiliation":[{"name":"Orthopaedic Research Institute, Saint George Hospital Campus, University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hilal S.
