Biomechanical Performance of Menisci under Cyclic Loads

The meniscus, composed of fibrocartilage, is a very important part the human knee joint that behaves like buffer. Located in middle femoral condyles and tibial plateau, it necessary structure to maintain normal biomechanical properties knee. Whether walking or exercising, meniscus plays vital role protect articular surface both plateau by absorbing conveying shock from body weight. However, modern people often suffer irreversible degeneration tissue due exercise-induced harm aging. Therefore, understanding its dynamic characteristics will help learn more about actual state motion avoid unnecessary injury. This study uses reverse engineering equipment, 3D optical scanner, plastic teaching model build geometry meniscus. Then, finite element method (FEM) employed obtain results show natural frequencies, mode shapes, fatigue life analysis with real material parameters. achieved can be applied do subsequent simulation analysis, reduce lower external impacts, manufacture artificial through engineering.
