Abstract
Although projects using vibration signals generated by the joint to detect joint disoeders are still experimental, vibration arthrometry has been shown to be useful in assessing meniscal pathology. A prospective study using vibration arthrometry to diagnose meniscal tears was carried out in 25 consecutive patients with knee injuries. They comprised 20 males and five females with an average age of 34 years. An arthroscopic examination of the injured knee was given to every patient. Six cases of mediall meniscal tear, 12 lateral miniscal tear, and two torn discoid menisci were found. The remaining five cases had normal menisci. By correlating the vibration arthrography of the patients to their corresponding arthroscopic findings, 15 were found to be true-positive, five true-negative and five false-negative . There were no false-positive readings. The accuracy, sensitivity and specificity of the vibration arthrometry in diagnosing miniscal tear was 80%, 75% and 100%, respectively . Vibration arthrometray was shown to be a reliable, non- ijnvasive diagnostic tool in diagnosing meniscal tear of the knee.#0629#
