OBJECTIVE
The study was performed to test the knot integrity of parallel and nonidentical sliding knots with the use of monofilament suture.
STUDY DESIGN
We investigated the proportion of parallel sliding knots that become untied compared with nonidentical sliding knots in four different monofilament suture configurations: group A, 6 throws, 0-0 gauge; group B, 10 throws, 0-0 gauge; group C, 6 throws, 2-0 gauge; group D, 10 throws, 2-0 gauge. Each combination was tested 20 times, for a total of 160 knots.
RESULTS
The nonidentical sliding knot untied 40% of the time in group A compared with 0% for the parallel knot (P=.003). In the other 6-throw group, group C, 45% of the nonidentical knots became untied compared with 0% of the parallel knots (P=.001). There were no significant differences in the proportions of untying for each knot type in the 10-throw groups.
CONCLUSION
Parallel sliding knots demonstrate superior knot integrity compared with nonidentical sliding knots with monofilament suture. The addition of throws to the nonidentical knot improves its knot security.
目的
本研究旨在使用单丝缝线测试平行和非相同滑结的结完整性。
研究设计
我们调查了在四种不同的单丝缝线配置中，与非相同滑结相比，平行滑结松开的比例：A组，6个线袢，0-0规格；B组，10个线袢，0-0规格；C组，6个线袢，2-0规格；D组，10个线袢，2-0规格。每种组合测试20次，共测试160个结。
结果
在A组中，非相同滑结有40%松开，而平行结为0%（P = 0.003）。在另一个6个线袢的组C组中，45%的非相同结松开，而平行结为0%（P = 0.001）。在10个线袢的组中，每种结类型的松开比例没有显著差异。
结论
与使用单丝缝线的非相同滑结相比，平行滑结表现出更好的结完整性。给非相同结增加线袢可提高其结安全性。
