使用尸体模型比较透视引导x线片与x线平片在显示未骨水泥全膝关节置换术胫骨部分下的透光线和该部分下沉的敏感性。透视引导的x光片可以精确测量一毫米宽的光线。射线平片不足以检测和测量这些透光线，导致不准确。透视引导下的x线片也可以测量胫骨成分和胫骨干骺端近端不透射线标记物之间的距离，可重现到半毫米以内。x光平片没有提供这个距离的可重复性测量。在全膝关节置换术后，推荐使用相对简单的x线透视技术来检测放射光线的存在和进展以及未骨水泥胫骨部件的下沉。
A cadaver model was used to compare the sensitivity of fluoroscopically guided radiographs with that of plain radiographs in revealing lucent lines beneath the tibial component of an uncemented total knee arthroplasty and subsidence of the component. Fluoroscopically guided radiographs allowed accurate measurement of a lucent line that was one millimeter wide. Plain radiographs were inadequate for the detection and measurement of these lucent lines, leading to inaccuracy. Fluoroscopically guided radiographs also allowed measurement of the distance between the tibial component and radiopaque markers in the proximal part of the tibial metaphysis that was reproducible to within one-half millimeter. Plain radiographs did not provide a reproducible measurement of this distance. The relatively simple technique of fluoroscopically guided radiography is recommended to detect the presence and progression of radiolucent lines and the subsidence of uncemented tibial components after total knee arthroplasty.
