The analysis of hip joint vibrations by various techniques (phonoarthrography, vibration arthrometry, vibroarthrography, hip auscultation) has been explored as a means to assess joint pathologies, disease status, and, recently, incipient prosthesis failure.
Vibration arthrometry in the patients with failed total knee replacement.
The most widely used method to assess the efficacy of knee bracing in-vivo has been the arthrometry test in which a device is externally strapped to the lower leg and the tibial translation is recorded during anterior shear loading (Beck et al.
During arthrometry, it is important that the patella is well stabilized against the femur, so that the relative movement of the tibiofemoral joint is measured as the relative motion between the patellar and tibial sensor pads of the arthrometer.
In order to justify these findings, one has to consider the functional bracing characteristics and the arthrometry test conditions in more detail.
Methods for clinical evaluation of knee joint stability comprise manual testing, radiographic studies, electromechanical studies, and arthrometry.
The greatest disadvantage of both manual testing and arthrometry is that they are static measurements and do not reflect what happens during dynamic activities.
Anteroposterior laxity was measured with KT-1000 arthrometry, and pivot shift testing was measured both clinically and by three-dimensional electromagnetic sensors.
KT-1000 or 2000 arthrometry is the most reliable and reproducible parameter for measurement of anterior translation available.
