Abstract

Articular cartilage is a special load-bearing material which protects joint surfaces with a remarkably low friction coefficient. Its mechanical properties have attracted interests both at research and clinical application level. This paper presents a study of nano-mechanical properties of cartilages. To better understand degradation processes of articular cartilage, an animal model was established to generate cartilage samples in different wear conditions. Using this controlled wear testing method cartilage samples in osteoarthritis (OA) grades 0-3 were obtained. The samples were nano-indented so their hardness and Young's modulus were studied to gain a better understanding of the nanomechanical properties of this complex, inhomogeneous material.
