Banddehnungsmessung am Kniegelenk - Der Dehnungsmeßstreifen und seine Alternativen

Those techniques for measuring ligament tension at the knee joint
that are most commonly cited and easiest to carry out are
discussed, These include four techniques based on the use of strain
gauges. Apart from the Omega transducer and the buckle transducer,
there is also the tendon force transducer, and the application of
strain gauges to the bony ligament insertion sites, Other indirect
measuring methods considered are the mercury strain transducer and
the Hall effect transducer. The parameter measured with all of
these methods is fluctuating current or voltage, which is then
correlated with ligament tension. Three direct measurements are
also discussed: the separation distances of marked fibres of the
ligaments, replacement of fibres by threads, and a load cell/bone
plug construction. The measured value is equated with the effective
change in ligament length.
