Abstract：
UNASSIGNED: Anterior cruciate ligament (ACL) reinjury after ACL reconstruction (ACLR) can occur on the ipsilateral or contralateral side. Limited evidence exists regarding the difference between the incidence of reinjury to either knee, which is important in developing interventions to prevent ACL reinjury.
UNASSIGNED: To compare the reinjury rate of the ACL on the ipsilateral side versus the contralateral side in athletes after ACLR and investigate the risk factors that may cause different reinjury rates between the sides.
UNASSIGNED: Systematic review; Level of evidence, 4.
UNASSIGNED: A systematic review was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies that involved ACL reinjury in athletes after ACLR were reviewed. Considering several risk factors, including age and sex, a comparison of ACL reinjury incidence on the ipsilateral and contralateral sides was performed using a meta-analysis.
UNASSIGNED: Of the 17 selected studies, 3 were found to be at high risk of bias, and thus, 14 (n = 3424 participants) studies were included in the meta-analysis. In this athletic population, the contralateral ACL had a significantly higher rupture rate than the ipsilateral graft (risk ratio [RR], 1.41; P < .0001). Female athletes were found to have a greater risk of ACL reinjury on the contralateral versus the ipsilateral side (RR, 1.65; P = .0005), but different results were found in male athletes. (RR, 0.81; P = .21). There was no statistical difference in the incidence rate of ACL reinjury to either side in adolescent athletes (RR, 1.15; P = .28).
UNASSIGNED: The contralateral ACL was more vulnerable to reinjury than the ipsilateral side in athletes after ACLR. Female athletes were more likely to reinjure their contralateral native ACL, while the same trend was not found in their male counterparts. The reinjury rate was comparable in both knees in adolescent athletes.

摘要：
■前交叉韧带（ACL）重建（ACLR）后再损伤可发生在同侧或对侧。关于任一膝关节再损伤发生率之间的差异的证据有限，这对于制定预防ACL再损伤的干预措施非常重要。
■比较运动员ACLR后同侧与对侧ACL的再损伤率，并调查可能导致两侧之间再损伤率不同的风险因素。
■系统评价；证据水平，4.
根据PRISMA（系统评价和荟萃分析的首选报告项目）指南进行系统评价。回顾了涉及ACLR后运动员ACL再损伤的研究。考虑到几个风险因素，包括年龄和性别,我们使用荟萃分析比较了同侧和对侧ACL再损伤的发生率.
■在选定的17项研究中，3人被发现有很高的偏见风险，因此，14项(n=3424名参与者)研究纳入荟萃分析。在这个运动人群中，对侧ACL的破裂率明显高于同侧移植物（风险比[RR]，1.41;P<.0001)。发现女运动员对侧与同侧的ACL再损伤风险更大（RR，1.65;P=.0005),但是在男性运动员中发现了不同的结果。(RR,0.81；P=.21）。青少年运动员两侧ACL再损伤发生率无统计学差异(RR，1.15；P=.28）。
■在ACLR后的运动员中，对侧ACL比同侧ACL更容易再受伤。女运动员更有可能再次伤害对侧原生ACL，而在男性中没有发现相同的趋势。青少年运动员的两个膝盖的再伤害率相当。
