摘　　要：背景:膝关节是人体的主要负重关节也是人体运动的中枢部位,其生理结构和运动构成较为复杂,在体育运动及日常生活中膝关节损伤较为常见,选择合适的膝关节生物材料进行修复或重建至关重要。目的:对膝关节生物材料的性能要求及临床应用情况进行概述,着重对生物材料的选择与其生物力学的相关性进行阐述与分析。方法:应用计算机检索PubMed、维普和万方数据库中1980-01/2011-10关于膝关节损伤治疗及其材料学方面的文章,在标题和摘要中以"膝关节;材料;力学"或"Knee;Materials;Mechanics"为检索词进行检索。最终选择27篇文章进行综述。结果与结论:在行膝关节再生或重建以及假体置换过程中,理想的材料学特征对治疗效果起着关键的制约作用,从对材料的选择与其生物力学的相关性来看,二者有着密切的相互促进和相互制约的关系。研究和开发理想的生物力学性能材料固然重要,同时运用合理的物理学手段对其进行改性或处理以达到理想力学性能材料的需求,也是切实可行的重要手段。BACKGROUND：Knee joint is the main weight loading joint of human body and the center part of human body motion.The physiologic structure and motion composition are very complex.Knee joint injury is common in sports and daily lift.Therefore,selection of appropriate knee joint biomaterials is critical for repair and functional reconstruction.OBJECTIVE：To summarize performance and clinical application of knee biomaterials and analyze selection of biomaterials and correlation with biomechanics.METHODS：A computer-based online search of PubMed,VIP and Wanfang database was performed for articles published between January 1980 and October 2011 regarding knee joint injury treatment and materials,with Key words ＂knee;materials;mechanics＂ in English and Chinese.Finally,27 articles were included. RESULTS AND CONCLUSION：During knee regeneration or reconstruction or prosthesis replacement,ideal materials play important roles in treatment effects.The selection of materials and biomechanics are closely correlated.Study and development of materials with ideal biomechanics are important,and modification for the materials is also necessary.
