The fluoroscopic double-contrast technique of arthrography of the knee is useful in documenting the extent of suspected injury to the knee. It is of particular value in demonstrating small and large lesions involving the menisci, cruciate ligaments, patellar cartilages, as well as the articular cartilages of the femoral condyles and tibial plateaus. This examination is instrumental in the diagnosis of the patient with an atypical history of injury and unusual physical findings. A simple restraint device allows the fluoroscopist complete control over the stress applied to the knee while positioning the patient for filming. Fluoroscopic spot radiographs of excellent contrast and sharp detail can be obtained of each of the various structures, applying the stress needed. When the radiologic technologist takes a little time to become more knowledgeable about the anatomy of the knee jount, and the rationale for the various views, the knee arthrographic examination is easily understood.
膝关节造影的透视双对比技术有助于记录膝关节疑似损伤的程度。它在显示涉及半月板、交叉韧带、髌软骨以及股骨髁和胫骨平台关节软骨的大小病变方面具有特殊价值。对于有非典型损伤病史和异常体格检查结果的患者，此项检查有助于诊断。一种简单的约束装置可让透视检查人员在为患者定位拍摄时完全控制施加于膝关节的应力。通过施加所需应力，能够获得各种结构的对比度极佳且细节清晰的透视点片。当放射技师花些时间更深入了解膝关节的解剖结构以及各种视图的原理时，膝关节造影检查就很容易理解了。
