The suture's knot site represents the highest amount and density of foreign body material of a knotted suture loop. The volume of a knot is directly related to the total amount of inflammatory reaction surrounding the knot. We measured the volume of seven surgical knots frequently used in surgical practice. Two different suture materials and two different sizes were tested. Suture size was found to contribute significantly more to the volume of all knots tested than the number of throws of which the knots were composed. Knots made with coated multifilament polyglactin-910 were significantly larger than the knots made with monofilament nylon. Clinical implications of these findings are discussed. Surgical techniques keeping the volume of knots to a possible minimum, are encouraged.
缝线的结部位代表打结缝线环中异物材料的最大量和密度。结的体积与结周围炎症反应的总量直接相关。我们测量了手术实践中常用的七种手术结的体积。测试了两种不同的缝线材料和两种不同的尺寸。结果发现，缝线尺寸对所有测试结的体积的影响比构成结的打结次数显著更大。用涂层多股聚乙醇酸-910制成的结明显大于用单丝尼龙制成的结。讨论了这些发现的临床意义。鼓励采用将结的体积保持在尽可能小的手术技术。
