A Review of the Vibration Arthrography Technique Applied to the Knee Diagnostics

Abstract

When a joint undergoes a range of motion, its constituents rub against each other, causing friction and thus vibrations. The vibration arthrography (VAG) technique consists of detecting, recording, and processing those vibrations to diagnose disorders. This non-invasive method could be an alternative to the currently used arthroscopy or X-rays. It has been revealed to be as accurate as these methods in terms of detecting pathologies such as osteoarthritis (OA). Moreover, vibrational analysis has highlighted some physiological signals associated with the displacement of knee joint components. Thus, vibroarthrography provides further understanding of the internal mechanisms of the knee joint. This paper aims to examine the research progress on the use of this vibration arthrography technique in diagnosing knee disorders.

“…So far, a number of studies have been carried out in the field on knee VAG signal identification and analysis [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. These studies show that, the use of accelerometers was preferred to stethoscopes and microphones because of their insufficient low frequency responses in defining knee related problems.…”
