ABSTRACT

Objective To investigate the diagnosis value of sonography for the meniscus lesions. Methods Sixty-six menisci of thirty-one patients examined by ultrasonography were compared with the arthroscopic operation or surgical findings. Results For all meniscal lesions,the ultrasound detecting gave an accuracy of (92.4)%,sensitivity of (94.1)%,specificity of (90.6)%,positive predictive value of (91.4)%,negative predictive value of (93.5)%.For medial meniscal lesions,the ultrasonography gave an accuracy of (87.9)%.For lateral meniscal lesions,the ultrasonography gave an accuracy of (97.0)%. The accuracies of locating the meniscal lesions and identifying the meniscal type were (85.3)% and (76.5)%,respectively.Using the miniwidth of meniscus at the midbody exceeds 15 mm as criterion,the accuracy of sonography indicating discoid meniscus was (88.9)%. Conclusions Ultrasonography can make relatively accurate diagnosis for meniscus lesions with its advantage of noninvasive convenience,and can be used as an auxiliary means to detect meniscus lesions.
