| description | In this paper, the numerical study focuses on the stress field of the knee meniscus in the two gaits of the jumping motion, and the knee injury and its knee protection effect are studied based on the stress field distribution characteristics of the knee meniscus. The jumping gait simulation was carried out by using a more detailed healthy knee model including bone, articular cartilage, meniscus, ligaments and peripheral soft tissues constructed by combining CT and MRI tomography, and the peak stress and its distribution area were analyzed based on the stress field characteristics of the meniscus, and the knee meniscus and its injury and protection under different knee pads were discussed. The results showed that the anterior angle of the meniscus on the medial knee joint was an area prone to injury in the take-off and landing gait. Under the knee pads, the peak stress of the meniscus decreases, and its distribution area gradually shifts from the anterior angle to the middle, and the functional knee pads with the optimized force load significantly alleviate the stress concentration of the meniscus. Therefore, the numerical study of the stress field of the knee meniscus provides theoretical support and optimization guidance for the design of functional knee pads. |
