The measurement of anteroposterior instability as well as lateral and medical instability in the knee joint based upon radiologic films exposed while forces are being exerted on the patient in a specially constructed stress apparatus is described. Measurements on the films require detailed knowledge of the landmarks of the joint, alignment of baselines to special points, especially on the lateral projection, where anterior and posterior displacement should be measured for each tibial condyle to calculate the mean.
描述了一种基于在特制应力装置上对患者施加力时拍摄的放射学影像，测量膝关节前后不稳以及内外侧不稳的方法。对影像的测量需要详细了解关节的标志点，将基线对准特定点，特别是在侧位投影上，对于每个胫骨髁都应测量前后移位以计算平均值。
