The aim of this study was to assess the QUESTOR Precision Radiography system (QPR) and to compare it with the routine hip-knee-ankle (HKA) angle measurements. The aim was also to evaluate the robustness of the QPR system against the osseous changes of arthrotic disease.
Twenty-four patients, operated on with a high tibial osteotomy for medial gonarthrosis, were examined. The alignment of the leg was measured by the conventional technique and by the QPR method.
The 2 methods correlated well. The intraobserver variation in the QPR measurements was, with the exception of the capito-midcondylar-femoral shaft angle and the tibial plateau width, not affected by the osseous changes inflicted by the arthrotic process. The patients tolerated both systems well while the staff preferred the QPR system.
本研究旨在评估QUESTOR精密放射成像系统（QPR），并将其与常规髋-膝-踝（HKA）角测量进行比较。其目的还在于评估QPR系统针对关节疾病骨改变的稳健性。
对24例行胫骨高位截骨术治疗内侧膝关节病的患者进行检查。采用传统技术和QPR方法测量下肢对线情况。
两种方法相关性良好。除头-髁间-股骨干角和胫骨平台宽度外，QPR测量的观察者内变异不受关节病变所致骨改变的影响。患者对两种系统的耐受性均良好，而工作人员更倾向于QPR系统。
