Abstract

Articular cartilage is a biological weight-bearing tissue covering the bony ends of articulating joints. Subtle changes in tissue composition can lead to degeneration of articular cartilage. This study develops an improved inhomogeneous triphasic model with four parameters and extracts the uniaxial modulus (Ha) for both normal and degenerated articular cartilage, and then predicts the swelling pattern of the cartilage. The results indicated that the new inhomogeneous triphasic model can extract uniaxial modulus more accurately, and the predict results also appeared to well match the experimental strain data. This inhomogeneous triphasic model can describe the depth-dependent material attribute of normal and degenerated articular cartilage more exactly.
