在全膝关节置换术(TKA)中，胫骨髓内或髓外定位导向器在进行胫骨切除时并不是非常准确。自2010年5月以来，共有42个膝关节接受了TKA，使用手持、基于加速度计的手术导航系统执行胫骨切除(Knee Align；OrthAlign Inc Aliso Viejo，加利福尼亚州)。术后站立髋关节前后位片和膝关节侧位片显示，97.6%的胫骨假体在冠状面与机械轴成90°+/-2度范围内，96.2%的假体在矢状面与机械轴成+/-2度范围内。膝关节对位大大提高了全膝关节置换术中胫骨假体对位的准确性。
Tibial intramedullary or extramedullary alignment guides have not been shown to be highly accurate in performing the tibial resection in total knee arthroplasty (TKA). Since May 2010, a total of 42 knees underwent a TKA using a hand-held, accelerometer-based surgical navigation system for performing the tibial resection (Knee Align; OrthAlign Inc Aliso Viejo, Calif). Postoperative standing anteroposterior hip-to-ankle and lateral knee-to-ankle radiographs demonstrated that 97.6% of the tibial components were placed within 90 degrees +/- 2 degrees to the mechanical axis in the coronal plane, and 96.2% of the components were placed within 3 degrees +/- 2 degrees to the mechanical axis in the sagittal plane. The Knee Align greatly improves the accuracy of tibial component alignment in TKA.
