Loads applied on the articular surface are transmitted through the articular cartilage, the subchondral bone and the cancellous bone to the shaft bone. The prosthesis for the artificial joint is a material replacing the articular cartilage and the subchondral bone. So, it is important for an effective design of the artificial joint possessing the mechano-compatibility to living bones to understand the mechanical behavior of them sufficiently. The purpose of this paper is to investigate the optimum design of the artificial joint by considering the better plate shapes of the prosthesis for the fixation on the cancellous bone under compressive loading based on the mechanical behavior of the subchondral bone. Consequently, the effectiveness of the optimum designs of the artificial joints using the arched plate prostheses is shown numerically.Read More
