Tensile and knot performance of polyester,silk,polypropylene and polydioxanone sutures

Suture is a generic term for all materials used to bring served body tissues together and to hold these tissues in their normal position until healing takes place. the success of a suture is generally linked to its mechanical performance such as tensile and knot strength. extensive research has been done on sutures,the majority of which focuses on tissue response to sutures,mechanical properties,knot properties,wound infection and degree of absorption. in this study,it is aimed to investigate the mechanical performance (tensile and knot strength) of materials such as polyester (pes),silk,polypropylene (pp) and polydioxanone (pdo). the obtained results showed that the mechanical performances of sutures are affected by sutures materials,sutures size and knot type. the developed model (tenacity 95 (cn/tex) and elongation 85 (%)) expresses with rather high accuracy the relation between independent variables and dependent variable and that experimental work results were acceptable as accurate.
