[Differentiation of functional knee movement in hemophilic patients by means of ultrasonic topometry (author's transl)].

First experiences using UST (Ultra-Sound-Topometry) in functional analyses of the loco motor system show: The motor patterns in gait analyses can be analyses can be visualized in such high steric- and time-resolution, that even slightest disturbances can be seen and localized. The high resolution of the procedure allows exact analyses of the movement patterns within the joints. In the knee, for example, we could demonstrate, how in slight to marked pathology the stress in the cartilagenous layers is disturbed in different ways. Out of this, conclusions, concerning the intraarticular destructions and their effects on the kibernetic chain, can be made.
