[Intra-articular pressure measurement. A new method for the use of the pressure measuring film "Prescale"].

We present a new procedure to protect Pressure measuring film from moisture and to facilitate its application in sphaerical joints without crinkles, shearing or friction artefacts. The film is cut into narrow laminas and embedded between two layers of an OP-site-foil. After this treatment, the film is still able to be gauged and even to bear a gas sterilization without any loss of measuring range or accuracy.
