This study fabricated size 2\u20130 PVDF and PP bidirectional barbed sutures and compared their mechanical properties and anchoring performance in patellar tendons. The mechanical properties were evaluated via tensile testing, and the anchoring performance of the barbed sutures was assessed by a tendon suture pullout test. Sixty porcine patellar tendons were harvested, transected to mimic a full\u2010thickness injury, and repaired using a cross\u2010locked cruciate suturing technique. The ultimate tensile force was 60% higher for the PVDF barbed sutures (22.4\u2009\u00b1\u20092.1\u2009N) than for the PP barbed sutures (14.0\u2009\u00b1\u20091.7\u2009N). The maximum pullout force was 35% higher for PVDF barbed sutures (70.8\u2009\u00b1\u20097.8\u2009N) than for PP barbed sutures (52.4\u2009\u00b1\u20095.8\u2009N). The force needed to form a 2\u2010mm gap, indicative of repair failure, was similar between the PVDF (29.2\u2009\u00b1\u20095.0\u2009N) and PP (25.6\u2009\u00b1\u20093.1\u2009N) barbed sutures, but both were greater than the 2\u2010mm\u2010gap forces for non\u2010barbed sutures of the same size. In this study, PVDF barbed sutures provided better mechanical properties and improved tissue anchoring performance compared to the barbed PP sutures for porcine patellar tendon repair, demonstrating that PVDF monofilament sutures can be barbed and used effectively for tendon repair.<\/jats:p>","DOI":"10.1002\/jbm.b.35074","type":"journal-article","created":{"date-parts":[[2022,6,8]],"date-time":"2022-06-08T07:10:20Z","timestamp":1654672220000},"page":"2258-2265","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Comparison
