摘　　要：目的:通过总结前交叉韧带重建的生物学及生物力学特性,探讨早期锻炼对膝关节前交叉韧带重建后移植物愈合及膝关节运动功能恢复的作用。资料来源:应用计算机检索MEDLINE1970-01/2004-01期间有关膝关节前交叉韧带重建及其生物力学特征的文献,检索词“anteriorcruciateligament,kneejoint,biomechanics”,并限定文章语言种类为英文。资料选择:对资料进行初审,选择有关膝关节前交叉韧带重建及其生物力学特征的文献,开始查找全文。选择随机对照类文章,当同一作者有多篇文章时,选择病例数最多的予以纳入;排除综述类及Mete分析类文章。质量评价主要考察资料的真实性,调查、实施过程是否严密。资料提炼:共检索到46篇有关膝关节前交叉韧带重建及其生物力学特征的文章,29篇符合以上纳入标准,排除的17篇文章中,9篇为小样本分析,8篇为综述类或Mete分析类文章。资料综合:通过了解正常前交叉韧带的生物力学特征制定重建措施及康复计划指导。重建后前交叉韧带动物实验提示膝关节运动功能恢复均不理想,而人体实验结果优于动物。随机对照实验表明,前交叉韧带重建后立即持重不增加膝关节的松弛性,反而有利于减轻髌骨疼痛。结论:前交叉韧带损伤重建后固定膝关节,限制关节周围肌肉收缩活动,导致韧带、关节及周围肌肉运动功能受限。早期康复锻炼可以减轻疼痛,改善关节软骨代谢,防止关节囊挛缩,有助于重建后膝关节前交叉韧带运动功能的恢复。OBJECTIVE： To probe into the function of early exercises on healing of grafts after anterior cruciate ligament （ACL） reconstruction and on motor function recovery of knee joint by summarizing biology and biomechanlcal properties of ACL reconstruction. DATA SOURCES： The relevant literatures on ACL reconstruction of knee joint and its biomechanical properties were looked up in period of MEDLINE1970-01/2004-01 on computer. Retrieval words： “anterior cruciate ligament, knee joint, biomechanics” only in English. STUDY SELECTION： In initial examination, the complete contents of literatures on ACL reconstruction of knee joint and its biomechanical properties were selected. The controlled papers were randomized, for those written by the same writer, the papers with the most cases were included. Comprehensive and Mete analyzed papers were excluded. Quality evaluation was mainly based on the reality of observed data and rigor of investigation and application. DATA EXTRACTION： Fourty-six papers on ACL reconstruction of knee joint and its biomechanical properties were looked up totally, of which, 29 papers were tallied with inclusive criteria, 17 papers were excluded, 9 papers were the analysis on small samples and 8 papers referred to comprehensive and Meta analysis. DATA SYNTHESIS： By understanding biomechanical properties of normal ACL, it is to implement reconstruction measures and plan for rehabilitation. Animal experiment after ACL reconstruction suggests that the motor function recovery of knee joint is not satisfactory, but the results of human experiment are superior to animal one. It is indicated in randomized control experiment that immediate weighthearing right after ACL reconstruction will not aggravate knee joint laxity; on the contrary, it is advantageous to alleviate patellar pain. CONCLUSION： Reconstruction of injured ACL fixes knee joints, limits peripheral muscle contraction and results in limited motor function of ligaments, joints and peripheral muscles.
