Abstract
Information on the effects of joint forces during human locomotion will be crucial in understanding the causes of musculoskeletal disorders, such as osteoarthritis [1]. Currently, direct in vivo stress-strain measurements of articular cartilage in human joints are not feasible. Subject-specific computational models, when effectively combined with useful experimental measurements, may help to overcome this problem. Due to high computational challenges, the previous computational models, e.g., for knee joint loading, have been over-simplified (linear or time-independent material models, geometry). Further, the motion capture (MOCAP) and ground reaction force (GRF) measurements, as well as imaging of the joint geometry, have not been conducted for the same individual [8,9]. The objective of this study was to present a computational framework for subject-specific calculation of cartilage stresses and strains in human knee joint during realistic locomotion. For this purpose, we established a stepwise approach using MOCAP, multibody simulation approach, and finite element (FE) method with a state-of-the-art material
