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.
目的
比较在单纯韧带撕裂的膝关节中，两个隧道位置的解剖学前交叉韧带（ACL）重建效果。
方法
对15个新鲜尸体标本从髋部到脚趾进行解剖学ACL重建。未制造相关损伤以增强膝关节不稳定性。实验方案分三种状态进行：（1）单纯ACL完全缺失；（2）解剖学股骨和胫骨前内侧ACL重建（AM REC）；（3）解剖学股骨和胫骨中央ACL重建（Central REC）。重建方案随机分配。使用跟踪系统动态记录连续机械性轴移试验。
结果
与AM REC组相比，Central REC组在轴移试验中内旋程度较小（分别为0.6°±0.3°和1.8°±0.3°，P<0.05），前向平移无差异（分别为4.7 mm±0.4 mm和4.5 mm±0.4 mm，P>0.05）。
结论
中央解剖学ACL重建比前内侧解剖学ACL重建导致更大程度的内旋受限。
