Analysis of the biomechanical characteristics of the knee joint with a meniscus injury

[摘要] The knee joint is one of the most important joints in the human body. The meniscus is a half-moon cartilage which locates between the medial and lateral condyle of the thighbone and the medial and lateral condyle of the shin in the knee joint, and it has multiple functions such as bearing load, cushioning and stabilising joints. It is easy to be injured because of its complex structure and functions. In this study, the physical fitness of patients with meniscus injury was tested using kinematic measurement, and the data were collected for biomechanical analysis on the parameters such as the angle and stress when the patient's bent knees during sports. The results demonstrated that the average values of bending angle, the rotation angle of the knee joint and intensity of pressure of the patients with meniscus injury were remarkably different with those of people without meniscus injury. Biomechanical characteristics are of extensive values to the treatment of meniscus injury.
