Indentation testing is a widely used technique for nondestructive mechanical analysis of
articular cartilage. Although cartilage shows an inhomogeneous, layered structure with
anisotropic mechanical properties, most theoretical indentation models assume material
homogeneity and isotropy. In the present study, quantitative polarized light microscopy
(PLM) measurements from canine cartilage were utilized to characterize thickness and
structure of the superficial, collageneous tissue layer as well as to reveal its relation to …
