Biomechanics of human knee joint based on finite element analysis

In this study, the biomechanical characteristics of the human knee joint were deeply discussed based on finite element analysis technology. By constructing a three-dimensional finite element model of the knee joint, the anatomical structure and biomechanical behavior of the knee joint are reproduced. The model takes into account the material properties of articular cartilage, ligaments, and muscles and simulates the knee response under different loads. The main objective of the study was to analyze the stress distribution of the knee joint during high-intensity exercise and daily activities, as well as potential injury mechanisms. The results show that there are significant differences in the pressure and stress of the knee joint under different exercise conditions, which is of great significance for the health and disease prevention of the knee joint. In addition, the finite element analysis also reveals the role and interrelationship of each component of the knee joint in load transfer. This study provides a theoretical basis for the diagnosis and treatment of knee joint-related diseases and lays a foundation for future biomechanical research and the formulation of personalized medical programs.
