Twelve kinds of knots commonly used in surgical practice were tested with respect to holding power, expressed as loop-holding capacity. Two synthetic absorbable suture materials were used: nonlubricated polyglycolic acid (Dexon-S) and lubricated polyglactin-910 (Vicryl). The knots were selected on the basis of an inquiry among 25 experienced gynecologists, well known in the field of gynecologic surgery. Five of the 12 knots were sliding knots, four were square knots, and the remaining three were surgical knots. Sliding knots were routinely used by 20 of the 25 respondents (80%). The loop-holding capacity of various knots differed widely, ranging from 5 to 65% of the tensile strength of the unknotted thread. Square knots were stronger than sliding knots, and, in general, the holding power could be increased by adding extra throws to the knot. The findings revealed that the properties of various knots used in surgical practice differ considerably. Therefore, sufficient knowledge about knot configuration and knot strength seems to be an important and basic aspect of surgical handicraft.
对手术中常用的12种结进行了持力测试，以环持力表示。使用了两种合成可吸收缝合材料：未润滑的聚乙醇酸（Dexon-S）和润滑的聚丙交酯-910（薇乔）。这些结是根据对25位在妇科手术领域知名的经验丰富的妇科医生的调查选定的。12种结中有5种是滑结，4种是方结，其余3种是外科结。25名受访者中有20名（80%）常规使用滑结。各种结的环持力差异很大，范围为未打结线抗张强度的5%至65%。方结比滑结更牢固，一般来说，通过增加结的额外缠绕可以提高持力。研究结果表明，手术中使用的各种结的特性差异很大。因此，充分了解结的构型和结的强度似乎是手术技术的一个重要且基本的方面。
