Tensile and knot properties of new generation (polyblend) and traditional suture materials in orthopedic surgery were investigated in standard laboratory conditions. Study focused on Fiberwire No. 5 and 2, Ethibond No. 5, 2 and 00, Orthocord No. 2, MaxBraid No. 2, Prolene No. 0 and 00, PDS No. 0 and 00, and Vicryl No. 2, 0 and 00. A 27-cm suture loop was fastened with 10 knots for ten samples for each type. Test parameters were tensile load to failure, elongation at failure point and knot slippage, and volume of 10-fold knots. Results were compared using ANOVA test. Failure load of No. 5 Fiberwire (625.0 ± 30.0 N) was significantly higher compared to all other suture types. Tensile strengths of MaxBraid No. 2 (287 ± 11 N) was significantly stronger compared to two other No. 2 polyblend sutures types and Ethibond No. 5. Knot slippage of Fiberwire No. 5 (14 ± 1.9 mm) was significantly higher compared to all other suture types. Ethibond No. 2 (0.1 ± 0.3 mm) had the lowest knot slippage. Elongation at the failure point of Fiberwire No. 2 (5%) was significantly lower than all other suture types. Mean calculated knot volume of #5 Fiberwire (73 ± 6.9 mm(3)) was significantly higher compared to #5 Ethibond (53 ± 4.8 mm(3)). Results of the study proved presence of significant differences between tensile and knot properties of various suture types and sizes. Loop security of larger diameter sutures is not always higher than thinner sutures. Suture elongation and knot slippage are important failure modes for high-diameter sutures and short-suture loops.
在标准实验室条件下，研究了骨科中新一代（多混合物）和传统缝线材料的拉伸和打结性能。研究集中在 Fiberwire No.5 和 2、Ethibond No.5、2 和 00、Orthocord No.2、MaxBraid No.2、Prolene No.0 和 00、PDS No.0 和 00 以及 Vicryl No.2、0 和 00。对于每种类型的十个样本，用 10 个结将 27 厘米的缝线环系紧。测试参数包括断裂时的拉伸载荷、断裂点的伸长率和结滑移以及 10 倍结的体积。使用方差分析测试比较结果。No.5 Fiberwire（625.0±30.0 N）的断裂负荷明显高于其他所有缝线类型。MaxBraid No.2（287±11 N）的拉伸强度明显强于另外两种 No.2 多混合物缝线和 Ethibond No.5。Fiberwire No.5（14±1.9 mm）的结滑移明显高于其他所有缝线类型。Ethibond No.2（0.1±0.3 mm）的结滑移最低。Fiberwire No.2 断裂点的伸长率（5%）明显低于其他所有缝线类型。#5 Fiberwire（73±6.9 mm³）的平均计算结体积明显高于#5 Ethibond（53±4.8 mm³）。研究结果证明了各种缝线类型和尺寸的拉伸和打结性能之间存在显著差异。较大直径缝线的环安全性并不总是高于较细的缝线。缝线伸长和结滑移是高直径缝线和短缝线环的重要失效模式。
