Although projects using vibration signals generated by the joint to detect joint disorders 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 medial meniscal tear, 12 lateral meniscal 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 meniscal tear was 80%, 75% and 100%, respectively. Vibration arthrometry was shown to be a reliable, non-invasive diagnostic tool in diagnosing meniscal tear of the knee.
尽管利用关节产生的振动信号来检测关节疾病的项目仍处于实验阶段，但振动关节测量法已被证明在评估半月板病变方面是有用的。对25例连续的膝关节损伤患者进行了一项使用振动关节测量法诊断半月板撕裂的前瞻性研究。他们包括20名男性和5名女性，平均年龄为34岁。对每位患者受伤的膝关节进行了关节镜检查。发现内侧半月板撕裂6例，外侧半月板撕裂12例，盘状半月板撕裂2例。其余5例半月板正常。通过将患者的振动关节造影结果与其相应的关节镜检查结果进行对比，发现15例为真阳性，5例为真阴性，5例为假阴性。没有假阳性读数。振动关节测量法诊断半月板撕裂的准确性、敏感性和特异性分别为80%、75%和100%。振动关节测量法被证明是诊断膝关节半月板撕裂的一种可靠的非侵入性诊断工具。
