中文摘要：

膝关节的运动损伤和累积疲劳损伤引起的骨性关节炎非常普遍，膝关节生物力学行为的研究在探求膝关节疾病的病因和发病机制、治疗和预防关节病方面起到重要作用，同时也有助于膝关节康复与矫形支具的设计．对于膝关节生物力学的研究可以采用试验法和有限元法，近年来有限元方法得到广泛的应用，而其进一步发展还有赖于关节骨及其组织细观结构与宏观力学性能的研究．

英文摘要：

Osteoarthritis caused by knee sports injuries and cumulative fatigue damage is very common. The research result of biomechanical behavior of the human knee is not only important to know the etiology and pathogenesis, improve the treatment of joint diseases, but also helpful to design the knee rehabilitation and orthopedic brace. The experimental method and simulation method are mainly used in the biomechanical research of the knee joints. The finite element simulation method has been widely used in recent years, and its further development has to depend on the knowledge of macroscopic mechanical properties and microscopic structure of joint bone and tissue.
