Abstract

Osteoarthritis is a joint disease where the articular cartilage is degenerated slowly. Articular cartilage play an important role in reduce the friction between the bone and act as the shock absorber. Therefore, this study aim to characterize the biomechanical properties by using MRI technique and the combination of experimental and computational method. The used of MRI is to observe the cartilage surface and obtain the grayscale of the image. The experimental method in this study is indentation test whereas computational method is finite element (FE) modelling of articular cartilage. In this study, the bovine hip joint was used to study the biomechanical properties of articular cartilage. Indentation test is used to study the creep behavior and thickness of articular cartilage. For FE modelling, it is used to create a FE model of articular cartilage based on the real specimen to simulate the creep indentation test. By combining both experimental and computational method, the biomechanical properties, elastic modulus and permeability can be estimated. Moreover, a correlation between the grayscale value and biomechanical properties also been done. From this correlation, it can be shown that the grayscale value has a significant effect on the biomechanical properties of articular cartilage.
