Patellar vibration is measured using a 2-g accelerometer. This is a sensor which, when taped to the skin over a joint, can detect underlying vibration. The technique of recording and analyzing this phenomenon has been called vibration arthrography. As the knee moves slowly (about three degrees per second) the normal patella produces a characteristic vibration called physiological patellofemoral crepitus. Experimental work has shown that this occurs as a result of stick slip friction at the cartilage interface. This technique therefore provides the potential for noninvasive examination of the mechanical properties of articular cartilage. However, difficulties have been encountered in the standardization of the signal due to its sensitivity to changes in angular velocity at the knee.
