我们用一种新的三维分析评估了37例初次全膝关节置换术的术后对齐情况，使用的是基于计算机断层扫描的导航系统(德国Brain Lab，向量视觉膝关节1.5)。股骨冠状角89.0°±1.4°(85.5°~92.8°)，胫骨冠状假体89.2°±1.0°(87.4°~91.6°)。髋膝踝角为178.2°±1.5°(173.9°~181.8°)。股骨假体相对于手术上髁轴的外旋方向为−0.5°±1.7°(−3.2°~3.4°)。结果表明，基于计算机断层扫描的导航系统提供了相当令人满意的部件对齐。−2.7°~3.4°，二维与三维测值相差0.3°±1.8°。为了评价导航系统的精度，需要进行三维分析。
We evaluated the postoperative alignment of 37 primary total knee arthroplasties performed using a computed tomography–based navigation system (Vector Vision Knee 1.5; Brain Lab, Germany) with a new 3-dimensional analysis. The mean coronal femoral angle was 89.0° ± 1.4° (85.5°-92.8°), and the coronal tibial component was 89.2° ± 1.0° (87.4°-91.6°). The hip-knee-ankle angle was observed to be 178.2° ± 1.5° (173.9°-181.8°). The external rotational alignment of the femoral component relative to the surgical epicondylar axis was −0.5° ± 1.7° (−3.2° to 3.4°). The results demonstrated that a computed tomography–based navigation system provided a reasonably satisfactory component alignment. The discrepancy between the 2-dimensional and 3-dimensional evaluations was 0.3° ± 1.8° (−2.7° to 3.4°). Three-dimensional analysis is necessary to evaluate the accuracy of the navigation system.
