Abstract:

Aiming at the graft failure of artificial ligaments under complex mechanical environment in the knee joint cavity, an artificial ligament fatigue testing device was built, composing of a tensile motion module, a torsion motion module, a flexion motion module and an insulation temperature liquid return system. Clinical physiological parameters such as tensile displacement, torsion angle and flexion angle of the human body during normal walking were selected for fatigue tests and evaluation of fatigue resistance of artificial ligament specimens. The results showed that the friction damage between fibers and yarns was the main fatigue damage mode of the specimens and the tensile property of the specimens suffered some loss after fatigue and the normalized tensile modulus decreased exponentially with time. The macromolecular chains of the specimens were subjected to a series of multi-directional loads such as tension, compression, torsion and flexion during the fatigue test, which ultimately led to a decrease in crystallinity.

Key words: artificial ligament, fatigue test, ligament graft, fatigue resistance, medical textiles
