Osteoarthritis (OA) is a major joint disease with cartilage degeneration. The quantitative examination of this disease is difficult because there is not an effective clinical method to measure mechanical properties of articular cartilage. We have been investigating the evaluation method of articular cartilage using ultrasonic and then measured in vivo mechanical properties of articular cartilage. In this paper, we examined that the present method could be applied to the quantitative evaluation of OA cartilage. Mechanical properties of articular cartilage of OA rabbit were measured. From the magnitude-duration time graph, the plotted point moved from left-upper area to right-lower area with the degree of OA. The result suggests that the quantitative evaluation of OA is possible from the mechanical properties of articular cartilage.
