目的: 通过介绍红外线计算机导航辅助下前十字韧带重建手术的术前规划及手术操作方法，探讨红
外线计算机导航对辅助关节镜下行前十字韧带( anterior cruciate ligament，ACL) 重建中股骨、胫骨隧道定位的准
确性及可行性并与传统关节镜重建术式进行比较。方法: 前瞻性分析同期2015－01 ～ 2016－06 期间，选取符合
ACL 损伤入组条件病人70 例，按照病人入院号末尾数字奇偶随机分为: 导航组与传统组，术后分别测量两组X
线片的胫骨隧道与股骨隧道位点，行Lachman 和KT－1000 试验稳定性检查，并采用Lysholm、Tegner，IKDC 评分
及膝关节ROM 对比，评价膝关节功能及运动水平。结果: 术后标准X 线片测量，分别行两组病人股骨隧道和胫
骨隧道位点统计学处理，数据显示二者均有显著性差异( P＜0．05) ，导航组标准差小于传统关节镜组，红外线计
算机导航辅助下ACL 手术组数据更接近解剖重建ACL 位置。Lachman 试验、KT－1000 试验、Lysholm、Tegner 评
分及膝关节ROM 两组差异无统计学意义。结论: 红外线计算机导航系统辅助关节镜下ACL 重建术是通过导航
下膝关节解剖标志运动学数据注册，确定骨道解剖学位点进行手术，该方法定位股骨、胫骨隧道位置精确，术后
疗效评价优良。

Objective: construction of the anterior cruciate ligament surgery introduced by infrared
navigation computer－assisted preoperative planning and surgical procedures， to explore the accuracy of
infrared computer assisted navigation former arthroscopic anterior cruciate ligament( anterior cruciate
ligament，ACL) reconstruction of the femur， tibia tunnel positioning and feasibility and with traditional
arthroscopic surgical reconstruction for comparison．Methods: retrospective analysis of the same period
from January 2015 to June 2016 period， the selected set of conditions into line with ACL injury 70 patients，
according to the number of patients admitted to hospital at the end of the digital parity were randomly
divided into: navigation group and traditional group． Postoperative tibial tunnel were measured
femoral tunnel sites and two X－ray film，and KT－1000Lachman test line stability check，and using Lysholm，
Tegner， IKDC score and knee ROM contrast，evaluation of knee function and activity level．Re-
sults: ostoperative standard X－ray measurements of femoral tunnel and tibial tunnel sites statistical data
show there were significant differences between the two group， the data show infrared navigation computer
assisted ACL surgery group data closer to the position of the anatomical ACL reconstruction．Lachman
test，KT－1000test，Lysholm，Tegner score and ROM，There was no significant difference between
the two groups． Conclusion: nfrared computer assisted navigation system arthroscopic ACL
reconstruction knee kinematics data registered by anatomical landmarks to navigate under way to determine
the anatomical site of bone surgery， the method of locating the femur， tibia tunnel precise location，
excellent postoperative patients．
