Abstract

ABSTRACT Objective: To compare anatomic anterior cruciate ligament (ACL) reconstruction between two tunnel positions in knees with isolated ligament tears. Methods: Anatomic ACL reconstruction was performed, from hip-to-toe, on 15 fresh cadaveric specimens. No associated lesions were created to enhance knee instability. The protocol was conducted in three states: (1) complete isolated ACL deficiency; (2) anatomic femoral and tibial anteromedial ACL reconstruction (AM REC); and (3) anatomic femoral and tibial central ACL reconstruction (Central REC). The reconstruction protocols were randomly assigned. The continuous mechanized pivot-shift test was recorded dynamically with a tracking system. Results: The Central REC group showed a smaller degree of internal rotation (0.6° ± 0.3° vs. 1.8° ± 0.3°, respectively, P < 0.05) and no difference in anterior translation (4.7 mm ± 0.4 mm vs. 4.5 mm ± 0.4 mm, respectively, P > 0.05) in the pivot-shift test, compared with the AM REC group. Conclusion: The central anatomic ACL reconstruction resulted in greater restriction of internal rotation than the anteromedial anatomic ACL reconstruction. Experimental Study on Cadaver.

前内侧或中央解剖前交叉韧带重建?对尸体的从头到脚的研究。

目的:比较孤立性韧带撕裂后膝关节前交叉韧带(ACL)两个隧道位置的解剖重建。方法:对15例新鲜尸体标本进行从髋到趾的解剖重建。没有相关病变增加膝关节不稳定性。该方案在三种状态下进行:(1)完全孤立的ACL缺陷;(2)解剖性股骨和胫骨前内侧ACL重建(AM REC);(3)解剖股骨和胫骨中央前交叉韧带重建(central REC)。重建方案随机分配。采用跟踪系统对连续机械化换挡试验进行动态记录。结果:与AM REC组相比，Central REC组的内旋度更小(分别为0.6°±0.3°和1.8°±0.3°，P < 0.05)，在枢轴移位测试中，前平移量无差异(分别为4.7 mm±0.4 mm和4.5 mm±0.4 mm, P > 0.05)。结论:中央解剖型前交叉韧带重建比前内侧解剖型前交叉韧带重建对内旋的限制更大。尸体实验研究。
