Abstract

Osteoarthritis is the most common form of arthritis. Nearly one in two people may develop symptomatic knee osteoarthritis by age 85 years in United State of America. It causes pain, swelling, and reduced motion in human joints. It was characterised by joint pain and malfunction of the joint, and then in further stage will be the joint contractures, muscles atrophy and limb deformity spine. The factors that cause osteoarthritis included overweight, joint injury, genetic defect in joint, etc. In previous studies, articular cartilage is usually study only based on certain thickness and flat cartilage surface to characterize the biomechanical properties. Therefore, this project will study on the effect of the cartilage thickness in indentation experiment and computational method in order to determine the biomechanical behaviours of cartilage. The actual cartilage surface in human synovial joint will be in either convex or concave shape or came in different size, this could affect the characterized properties. Hence, this project is will be using indentation testing and computational method of ABAQUS software in determining the biomechanical behaviours such as the pore pressure and contact pressure of the cartilage caused by different thickness of cartilage. As the thickness of the cartilage changes, the pore pressure and contact pressure will be affected. It is suggested that further study of the biomechanics of human cartilage and its applications will gain from the incorporation of existing engineering techniques and the advanced evolution of new technology.
