膝关节交叉韧带重建与生物材料的选择:在跆拳道运动中的特点

背景:膝关节交叉韧带的重建与人工韧带的选择有密切的关系.目的:通过检索相关文献,综述跆拳道运动员膝关节交叉韧带损伤的原因、膝关节交叉韧带重建和人工生物材料的选择问题,探讨人工韧带的重建、功能恢复及其临床效果的关系.方法:应用网络http://www.highwire.org/, http://www.chkd.cnki.net/index.htm/, 检索1999-01/2009-10的相关文献,检索词"Sport Training Dept, anterior cruciate ligament, ACL", 限定文章语言种类为English;并用检索词"跆拳道,膝关节前交叉韧带",限定文章语言种类为中文,检索相关的博士硕士论文,以及相关的中英文会议论文集.另外手工查找膝关节前交叉韧带有关的资料和书籍.排除实验设计不合理的文章及观点模糊的综述.结果与结论:①膝关节损伤是跆拳道运动常见的伤病,膝关节交叉韧带的重建,人工韧带的选择很关键.采用何种材料主要考虑一定形态、大小的移植物的强度、移植物的愈合过程、供区的损坏程度以及移植后能否建立与正常韧带组织相似的附着点.②人工合成材料重建交叉韧带的应用成败主要取决于其组成材料.材料的生物性、机械性是否能与正常韧带生物相容性和生物力学匹配制约着手术的成败.采用理想的生物材料修复韧带,可避免因自体取材的附加损伤.③人工合成材料重建交叉韧带的特点:可避免取材部位的并发症;关节镜下手术操作简便,手术时间短,创伤小;术中即刻获得足够抗拉强度;术后能够早期活动,恢复快;并发症少.临床上近期效果满意,远期效果还需进一步观察证实.

Reconstruction of cruciate ligaments of the knee joint and selection of biomaterials:Characteristics in Taekwondo athletics

BACKGROUND:Reconstruction of cruciate ligaments of knee joint is closely associated with the selection of artificial ligament.OBJECTIVE:To explore the associations among artificial ligament reconstruction,functional recovery and clinical effectiveness by summarizing reasons for cruciate ligament injury,reconstruction of cruciate ligament,and the selection of artificial ligament in Taekwondo athletes.METHODS:Documents published between January 1999 and October 2009 were searched on line http://www.highwire.o...
