摘要

Recent advances in surgical tools such as navigation systems have contributed to accurate implantation in total knee arthroplasty. Although several navigation systems have been developed, reports regarding which navigation system has better accuracy are few. Therefore, this study aimed to compare the accuracy of postoperative coronal alignment among 3 navigation systems. A total of 90 knee prostheses were implanted for 90 patients with osteoarthritis. Thirty patients were enrolled in each of the following 3 navigation groups: Stryker Navigation System II (computed tomography-free navigation; Stryker, Mahwah, New Jersey); OrthoPilot version 4.2 navigation system (computed tomography-free navigation; B. Braun Aesculap, Tuttlingen, Germany); and VectorVision navigation system (computed tomography-based navigation system; BrainLAB, Munich, Germany). Thirty consecutive total knee arthroplasties performed via the conventional method without navigation were selected as a control group for comparison with the navigation groups. Postoperative coronal mechanical axis and femoral and tibial coronal component angles were compared among the groups using long-leg standing radiographs for the rate of outliers beyond 3 degrees. No differences were observed in the mean femoral and tibial component angles among the navigation and conventional groups. However, the proportion of outliers beyond 3 degrees was higher in the conventional group than in the 3 navigation groups. No significant differences in the outlying values were found among the 3 navigation groups. These 3 navigation systems achieved equally accurate coronal mechanical alignment with fewer outliers. The navigation systems exhibited more precise implantation than the conventional method.

Braun Aesculap，德国Tuttlingen）;和VectorVision导航系统（基于计算机断层扫描的导航系统; Brainlab，慕尼黑，德国）。选择通过常规方法进行的30个连续总膝关节缩节塑化剂，无需导航作为对照组，以与导航组比较。使用长腿站立射线照片比较术后冠状机械轴和股骨和胫骨冠状轴分量角，以便超出3度超过3度的异常值。在导航和常规组之间的平均股骨和胫骨分量角中没有观察到差异。然而，传统组超过3度超过3度的异常值比例比3导航组更高。在3个导航组中发现了偏远值的显着差异。这3个导航系统实现了与较少异常值更准确的冠状机械对齐。导航系统表现出比传统方法更精确的植入。
