前交叉韧带内增强修复的研究现状

Current research in anterior cruciate ligament repair with internal brace

前交叉韧带(anterior cruciate ligament,ACL)断裂无法愈合的观念近年来随着对基础生物学认识的提高正在发生改变。内增强技术的引入使人们对急性ACL断裂的修复重新产生了兴趣。内增强技术可以通过分担ACL修复后负荷以减少松弛和微动,为ACL组织愈合提供稳定的环境。ACL内增强修复是一种很有前途的治疗急性近端ACL断裂的方法,它不仅可以达到标准前交叉韧带重建(anterior cruciate ligament reconstruction,ACLR)的疗效,而且可以减轻疼痛,加快康复。然而,在选择患者时年龄、运动水平和治疗时机等方面目前尚缺乏量化标准。本文针对前交叉韧带内增强修复的应用进展进行综述,综合评估该技术的实际意义。

The concept that torn anterior cruciate ligament(ACL)cannot heal is changing with the comprehensive understanding the basic biology in recent years.There has been a renewed interest in repair of acute ACL tear with newer internal brace technique,which had been proven to reduce relaxation and micromotion by sharing the load of ACL after repair,and provides a stable environment for ACL tissue healing.The ACL repair with internal brace technique is a promising treatment for acute proximal ACL tear,which not only lead almost the equivalent efficacy to standard anterior cruciate ligament reconstruction(ACLR),but also reduce the pain and speed up the rehabilitation.However,there still is a lack in terms of quantitative standards of age,level of sports participation and timing of treating while patient select⁃ed.In this paper,research progress in anterior cruciate ligament repair with internal brace is reviewed to evaluate the practical significance of this technique.
