The Value of Sonography in Diagnosis of Meniscal Injury

Background: Regarding the high incidence of meniscal injuries, a cost-effective, noninvasive, and also accurate diagnostic modality is highly needed. This study was conducted to assess the diagnostic value of sonography in detecting meniscus tears in comparison with arthrography. Methods: A total of 136 patients with symptoms of meniscal injury were examined with both sonography and arthrography by separate radiologists. The sensitivity, specificity, positive, and negative predictive values of sonography were calculated versus arthrography. Results: The sensitivity of sonography in diagnosing meniscus tear was 75 percent, specificity 88 percent, positive predictive value 80 percent, and negative predictive value 85 percent. Conclusion: Our results show that we can’t yet replace other methods with higher diagnostic value with sonography completely but regarding its advantages, it can be used along with other routine modalities.
