To assess the ability of anatomic double-bundle anterior cruciate ligament reconstruction in eliminating the pivot-shift phenomenon when identified by a quantitative measuring system (computer navigation or magnetic resonance imaging).
Literature review. Medline, Google Scholar and Cochrane Reviews computerized databases research using the keywords "pivot-shift," "anterior cruciate ligament reconstruction" and "double bundle." Twelve (7 in vitro and 5 in vivo) studies met the inclusion criteria.
There was a wide variation in the absolute value of translation and rotation measured after anatomic double-bundle anterior cruciate ligament reconstruction. There were also differences in fixation methods, pivot-shift execution conditions, applied stresses during the pivot-shift, calculation methods and reference systems utilized by measurement systems.
The double-bundle reconstruction was shown to over-constrain the knee with respect to the intact value, especially closer to knee extension. This review demonstrated that anatomic double-bundle anterior cruciate ligament reconstruction is able to eliminate pathological translations and rotations during the pivot-shift phenomenon, as identified by quantitative measurement systems.
Review of Level III studies, Level III.
通过定量测量系统（计算机导航或磁共振成像）评估解剖双束前交叉韧带重建消除“枢轴点移位”现象的能力。
文献回顾。使用关键词“枢轴点移位”、“前交叉韧带重建”和“双束”在 Medline、Google Scholar 和 Cochrane Reviews 计算机数据库中进行研究。
解剖双束前交叉韧带重建后测量的平移和旋转绝对值存在很大差异。固定方法、枢轴点移位执行条件、枢轴点移位过程中施加的应力、测量系统使用的计算方法和参考系统也存在差异。
与正常值相比，双束重建对膝关节的约束过度，尤其是在接近膝关节伸展时。本综述表明，解剖双束前交叉韧带重建能够消除定量测量系统识别的“枢轴点移位”现象中的病理性平移和旋转。
