Friction knot terminology is inconsistent in veterinary surgery

The objective of this study was to determine the nomenclature for friction knots commonly used by veterinary surgeons. Veterinary surgeons certified by the American College of Veterinary Surgeons (ACVS) or the European College of Veterinary Surgeons (ECVS) were recruited through email listings available on the websites of veterinary schools and the ACVS to participate in a survey on this subject. Participation was also solicited through the ACVS Facebook page, the Society of Veterinary Soft Tissue Surgery, and the Veterinary Orthopedic Society. The survey included questions about 4 knot-tying videos. Complete responses were received from 160 veterinary surgeons. Familiarity with the knots ranged from 26% (constrictor knot) to 54% (miller's knot). The modified miller's knot and the miller's knot were correctly named by a majority of surgeons (61% and 63%, respectively). There was no consensus for the constrictor knot, with the greatest number of respondents identifying it as the constrictor knot (38%) or the miller's knot (31%). There was also no consensus for the strangle knot, with respondents split among identifying it as the miller's knot (39%), modified miller's knot (34%), or strangle knot (21%). There is apparent disagreement on the names of surgical friction knots among veterinary surgeons. Many participants indicated that they were not familiar with the knots demonstrated in the videos. Inconsistent terminology may impede educational efforts and hinder clear communication about types of knots.
