Mechanical properties of articular cartilage elucidated by osmotic loading and ultrasound

S Tepic et al. Proc Natl Acad Sci U S A. 1983 Jun.

Abstract

The time response of surface displacement and acoustic impedance of in situ layers of articular cartilage were measured by using pulse-echo ultrasound. Disturbances were introduced by altering the osmotic pressure. Strongly nonlinear behavior was observed near physiological equilibrium. A model of articular cartilage is proposed which relates our results to cartilage microstructure.
