Two observers measured the tibiofemoral angle of 60 knees on hip-knee-ankle and anteroposterior (AP) knee radiographs and repeated the measurements 6 months later. Intraobserver reproducibility was moderate. Interobserver reliability was poor. These findings were the same irrespective of which radiograph was used during the measurement. Hence, although an AP knee radiograph was as reliable and reproducible as the hip-knee-ankle view, the radiographic tibiofemoral angle should not be considered a precise measurement.
两名观察者在髋关节-膝关节-踝关节位和膝关节前后位（AP）X线片上测量了60个膝关节的胫股角，并在6个月后重复测量。观察者内的可重复性为中等。观察者间的可靠性较差。无论测量时使用哪种X线片，这些结果都是相同的。因此，尽管膝关节AP位X线片与髋关节-膝关节-踝关节位片一样可靠且可重复，但影像学胫股角不应被视为精确测量值。
