The aim of this study was to evaluate the alignment of the distal femoral cutting surface using a navigation system to determine the accuracy of bone cutting. We evaluated 20 knees in 20 patients. After cutting the distal femur, the cutting surface was validated using the navigated cutting block adapter, and the angular difference between the cutting surface and that preoperatively planned in the sagittal and coronal planes was recorded. The average error of all knees was 1.6° ± 2.2° in extension, and 14 (70%) of 20 knees were cut in an extended position. Our tendency is to cut the distal femur in an extended position with the first femoral cut in the sagittal plane.
本研究旨在评估使用导航系统对股骨远端切骨面进行对线的准确性，以确定截骨的精度。我们评估了 20 名患者的 20 个膝关节。在完成股骨远端截骨后，使用导航截骨块适配器对切骨面进行验证，并记录切骨面与术前在矢状面和冠状面规划的切骨面之间的角度差异。所有膝关节的平均误差为伸直位 1.6°±2.2°，20 个膝关节中有 14 个（70%）为伸直位截骨。我们倾向于在股骨的首一切骨平面位于矢状面时将股骨远端切骨面置于伸直位。
