In this study, we compare the biomechanical performance of asymmetric repairs using 3 suture materials: Supramid Extra II 4-0, Tendo-Loop 4-0, and FiberLoop 4-0. <\/jats:p><jats:p> Methods: We divided 30 porcine flexor tendons into 3 arms. Each arm of tendons were repaired by using 1 of the 3 proposed suture materials. Each repaired tendon was tested by using a mechanical tester. Ultimate tensile strength (UTS), load to 2 mm gap force, failure mechanism and stiffness of the tendons were investigated. <\/jats:p><jats:p> Results: FiberLoop\u00ae achieved the highest UTS (90.4 \u00b1 17.9 N), followed by Tendo-Loop (85.3 \u00b1 10.3 N). The difference was no statistically significant. The UTS of repairs using Supramid\u00ae was significantly lower (64.0 \u00b1 8.4 N). For load to 2 mm gap force, FiberLoop\u00ae achieved 20.7 \u00b1 4.8 N while Tendo-Loop\u00ae had 20.5 \u00b1 4.2 N. The difference was also no statistically significant. The repairs using Supramid\u00ae had a significantly lower load to 2 mm gap force of 14.2 \u00b1 2.7 N. The stiffness of asymmetric repairs using FiberLoop\u00ae and Tendo-Loop\u00ae was 5.64 \u00b1 1.7 N\/mm and 5.63 \u00b1 0.7 N\/mm. The difference was also no statistically significant. The repairs using Supramid\u00ae had a significantly lower stiffness of 4.15 \u00b1 1.0 N\/mm. Failure mechanisms for the repaired specimens were reported as such: Supramid had 100% suture rupture; Tendo-Loop had 90% suture rupture and 10% suture pullout; FiberLoop had 20% suture rupture and 80% suture pullout. <\/jats:p><jats:p> Conclusions: The asymmetric repair configuration is able to produce superior biomechanical performance by using Tendo-Loop\u00ae or FiberLoop\u00ae. Improvement of the asymmetric technique by using Tendo-Loop\u00ae or FiberLoop\u00ae could potentially contribute to better surgical outcomes of flexor tendon repair. <\/jats:p>","DOI":"10.1142\/s2424835521500582","type":"journal-article","created":{"date-parts":[[2021,6,19]],"date-time":"2021-06-19T05:12:29Z","timestamp":1624079549000},"page":"611-617","source":"Crossref","is-referenced-by-count":5,"title":["Biomechanical Study of Asymmetric Flexor Tendon Repair Using 3 Different Suture Materials"],"prefix":"10.1142","volume":"26","author":[{"given":"Shuo Ling","family":"Teo","sequence":"first","affiliation":[{"name":"Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajragavan","family":"Sarvananthan","sequence":"additional","affiliation":[{"name":"Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca Qian Ru","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Hand & Reconstructive Microsurgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoke Rung","family":"Wong","sequence":"additional","affiliation":[{"name":"Biomechanics Laboratory, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2021,11,9]]},"container-title":["The Journal of Hand Surgery (Asian-Pacific Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S2424835521500582","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,18]],"date-time":"2021-11-18T04:03:00Z","timestamp":1637208180000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S2424835521500582"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,11,9]]},"references-count":0,"journal-issue":{"issue":"04","published-print":{"date-parts":[[2021,12]]}},"alternative-id":["10.1142\/S2424835521500582"],"URL":"https:\/\/doi.org\/10.1142\/s2424835521500582","relation":{},"ISSN":["2424-8355","2424-8363"],"issn-type":[{"value":"2424-8355","type":"print"},{"value":"2424-8363","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,11,9]]}}}
