在100例由同一名外科医生完成的连续初次全膝关节置换术中，对使用髓外和髓内导向器准备胫骨进行了比较研究。每种类型的导向器用于连续50例，共计100例。在所有病例中，使用髓内导向器准备股骨远端。术后拍摄长（髋关节至踝关节）前后位X线片，测量机械角、胫骨组件角、股骨组件角、生理外翻角和胫股角。未发现髓外和髓内组之间存在显著差异;每种系统均可实现满意的对线。对于外科医生来说，重要的是要了解每种导向器的优点和缺点，并在每个特定情况下使用最合适的导向器。
Use of extramedullary and intramedullary guides to prepare the tibia was studied comparatively in 100 consecutive primary total knee arthroplasties done by a single surgeon. Each type of guide was used in 50 consecutive cases, for a total of 100 cases. In all cases, an intramedullary guide was used to prepare the distal femur. Long (hip to ankle) anteroposterior radiographs were taken postoperatively to measure the mechanical angle, tibial component angle, femoral component angle, physiologic valgus angle, and tibiofemoral angle. No significant differences between the extramedullary and intramedullary groups were found; each system allowed satisfactory alignment. It is important for the surgeon to appreciate the benefits and deficiencies of each guide and to use whichever is suited most properly in each particular case.
