In this study, the mechanical properties of the menisci of patients with osteoarthritis who underwent knee replacement operations were evaluated. The analyzes were performed through stress-relaxation unconfined compression tests. The resulting curves were analyzed using a poroviscoelastic model. Finally, the results of the analysis, such as porosity, equilibrium and mean Young's modulus, were compared with literature data on healthy patients.

Utilisation des équipements

Un Mach-1 V500CSS testait des ménisques humains arthrosiques en compression non confinée avec relaxation. Un indenteur plat de 12,5 mm et une cellule de 250 N appliquaient des déformations successives, séparées par des maintiens. La réponse permettait d’estimer les propriétés mécaniques et d’ajuster un modèle constitutif.
