Thread samples (n = 8) were subjected to a load-to-failure test at 0.1, 0.5, 1, 5, and 10 mm\/s without previous loading history and after 10 cycles of loading at 1\u201310 N, 1\u201330 N, and 1\u201350 N. The experimental data were fitted to mathematical models to compute the stress\u2013strain relation and the strength of the suture. The bilinear model involving two stress\u2013strain ratios for low- and high-strain intervals was the best fit. The ratio in the low-strain range rose with loading speed, showing mean increases of 5.9%, 6.5%, 7.9%, and 7.3% between successive loading speeds. Without a previous loading history, this ratio was less than half than that at high strain. However, 10 cycles of 1\u201330 N or 1\u201350 N significantly increased the stress\u2013strain ratio at a low strain level by 135% and 228%, respectively. The effect persisted after 2 min but vanished after 24 h. No influence was found on the suture strength. In conclusion, the stiffness of the studied suture was influenced by the strain level, loading velocity, and recent cyclic loading history. Conversely, the suture strength was not affected.<\/jats:p>","DOI":"10.3390\/ma15072573","type":"journal-article","created":{"date-parts":[[2022,3,31]],"date-time":"2022-03-31T21:34:29Z","timestamp":1648762469000},"page":"2573","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Influence of Loading Conditions on the Mechanical Performance of Multifilament Coreless UHMWPE Sutures Used in Orthopaedic Surgery"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2639-0452","authenticated-orcid":false,"given":"Maria","family":"Prado-Novoa","sequence":"first","affiliation":[{"name":"Clinical Biomechanics Laboratory of Andalusia, University of Malaga, Calle Dr. Ortiz Ramos s\/n, 29071 Malaga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Perez-Sanchez","sequence":"additional","affiliation":[{"name":"Clinical Biomechanics Laboratory of Andalusia, University of Malaga, Calle Dr. Ortiz Ramos s\/n, 29071 Malaga, Spain"},{"name":"Telecomunication Research Institute (TELMA), University of Malaga, E.T.S.
