Abstract
Herein, a method was proposed for testing the dynamic tensile properties of a sports medicine suture and investigating the fatigue properties and elongation of the suture after a fatigue test. A test device was designed to test the dynamic tensile properties of sutures. The endurance limit of Nos. 1 and 4 sutures, which were used for laboratory comparisons, was [Formula: see text][Formula: see text]N and [Formula: see text][Formula: see text]N and the elongation rate was [Formula: see text], respectively. Furthermore, the Z-score, which is the offset divided by the standard deviation, was [Formula: see text]. The proposed test method is accurate and the repeatability is satisfied, making it suitable for determining the dynamic tensile properties of sutures. It is used as an industry standard to provide technical support for supervising sports medicine sutures.
