The aim of the study was to assess the consistency of the non-image-based navigation system OrthoPilot, Aesculap, Tuttlingen, Germany, in total knee arthroplasty (TKA) implantation in 5 European centers. Two hundred thirty-five TKAs implanted with this navigation system were matched (according to severity of the preoperative coronal deformation and body mass index) to a historical control group of 235 TKAs implanted with a conventional technique. Consistency of implantation was studied on a 3-month postoperative radiological control with coronal long-leg and sagittal standard x-rays. The use of the OrthoPilot navigation system allowed a statistically significant improvement in the consistent placement of both tibial and femoral components. In accordance with current literature, survival of the navigated implanted prostheses is expected to be longer.
本研究的目的是评估德国图特林根市蛇牌公司生产的非图像导航系统OrthoPilot在欧洲5个中心进行全膝关节置换术（TKA）植入时的一致性。将采用该导航系统植入的235例TKA（根据术前冠状面畸形严重程度和体重指数进行匹配）与采用传统技术植入的235例TKA历史对照组进行对比。通过术后3个月的冠状位长腿和矢状位标准X线片进行放射学对照研究植入的一致性。使用OrthoPilot导航系统在胫骨和股骨假体的一致性放置方面有统计学意义的显著改善。根据当前文献，预计导航植入假体的生存率会更高。
