我们进行了这项前瞻性随机和外部评价研究，以调查在全膝关节置换术中使用导航系统是否比手动引导技术获得更好的结果。共有240名患者被纳入研究。所有患者均接受髁状膝关节假体。两名外科医生使用斯特赖克膝关节导航系统进行了所有手术。排除标准包括主要使用限制型植入物的必要性，结果显示两组之间在机械轴、股骨额面和矢状面轴以及胫骨额面轴方面存在非常显著的差异，有利于导航（p < 0.0001）。因此，使用导航系统可改善植入物对线。
We conducted this prospective randomised and externally evaluated study to investigate whether the use of a navigation system during total knee arthroplasty leads to significantly better results than the hand-guided technique. A total of 240 patients was included in the study. All patients received a condylar knee prosthesis. Two surgeons performed all the operations using the Stryker knee navigation system. Exclusion criteria included the necessity for the primary use of constrained implants.The results revealed a highly significant difference between the two groups in favour of navigation with regard to the mechanical axis, the frontal and sagittal femoral axis and the frontal tibial axis (p < 0.0001). The use of a navigation system was therefore shown to improve the alignment of the implant.
