Arthroscopic knots: Suture and knot characterisation of modern polyblend suture materials

ObjectiveThe primary aim of this study was to explore the relationship between biophysical structure and function modern suture materials. Particularly suture's ability withstand stressors surgery how material properties affect knot stability. The secondary investigate effect that different knots have on itself. This builds previous research assessing characteristics but in Ultra High Molecular Weight Polyethylene (UHMWPE) materials currently widespread clinical use arthroscopic surgery.MethodsThree common UHMWPE sutures one polyester were tested both a dry wet state using Geelong, Nicky's, Surgeon's Tautline knots. Tensile strength vertically at 60 mm/min strain rate 45 mm gauge length. Sutures tied through cannula around two 8 diameter circular bollards. Testing conducted controlled environment temperature humidity (20 ± 2 °C, 65 2%).ResultsNo type optimal over all types. Mean tensile low coefficient variation (CV) considered as an indication suitability. With Ethibond Geelong (CV:4.2%). Orthocord (CV:4.2% CV:11.9% respectively). FiberWire Nickys (CV:22.6% CV:22.5% ForceFiber four exhibited similar with high variability showing should perform way invivo.ConclusionsThis demonstrates statistically significant three-way interaction polyblend materials, environment. has implications for security environments, may not behave same under conditions.
