Lactomer and Polyglactin 910 sutures are both made of copolymers of lactide and glycolide. Biomechanical performance tests demonstrated superior handling characteristics of the Lactomer sutures. Using sutures comparable in size and knot construction, the Lactomer sutures exhibited knot holding force superior to the Polyglactin 910. Moreover, the low knot rundown forces encountered by the Lactomer sutures facilitated construction of secure knots that failed by breakage rather than by slippage.
聚乙交酯丙交酯缝线和聚乙醇酸910缝线均由丙交酯和乙交酯的共聚物制成。生物力学性能测试表明聚乙交酯丙交酯缝线具有更优异的操作特性。使用尺寸和打结结构相当的缝线时，聚乙交酯丙交酯缝线的打结握持力优于聚乙醇酸910缝线。此外，聚乙交酯丙交酯缝线的低解结力有助于形成牢固的结，这种结是因断裂而非滑脱而失效。
