Application guidelines for dynamic knee joint analysis with a dual fluoroscopic imaging system.

The widespread availability of mobile digital fluoroscopic systems with dynamic imaging capabilities places this type of motion analysis within reach of many research groups. With the addition of the second fluoroscope though, and the incorporation of a treadmill to analyze gait, the fluoroscopic analysis technique, which was once a rather straightforward method, has become more complex. Therefore, the purpose of the present manuscript was to provide a comprehensive review of the various processes that are associated with the dynamic knee joint motion analysis, including patient selection, construction of three-dimensional knee models, fluoroscopic scanning, and matching.
