Objective: The objective of the research was to determine the correctness of high-frequency ultrasonography in knee joint meniscal injuries in matured patients verified on magnetic resonance imaging. Material and Method: This cross-sectional research was carried out at Mayo Hospital, Lahore from September 2018 to May 2019. The numbers of patients enrolled for research were one hundred with the supposition of meniscal injuries. The age of the enrolled patients was between fifteen to fifty years and comprising of both the genders. A researcher not included those patients in his research who have open wound over the knee, cases with former meniscal tears follow up and those patients having disease mimicking meniscal wounds. Researcher compares the ultrasonography results with the results of MRI which was carried out and explained by radiologist. Results: Among one hundred enrolled patients for research, ultrasound displayed meniscal injuries in seventy-five percent cases. Magnetic resonance imaging verified meniscal injuries in seventy-seven percent of patients. However, twenty-three percent displayed no meniscal injuries. In ultrasonography positive cases, the percentage of true positive and false positive cases was 72% & 3% respectively. Moreover, in twenty-five ultrasonography negative cases, five percent (false negative) has meniscal injuries verified through magnetic resonance imaging whereas twenty percent true negative had nil meniscal injury on magnetic resonance imaging. Therefore, negative and positive predictive value, specificity, diagnostic correctness, sensitivity in detecting meniscal injuries via ultrasonography was 80%, 96%, 86.96%, 92% and 93.50% respectively. Conclusion: This research determines that high-resolution ultrasonography emerges as safe, trustable, precise, available with ease as well as cost-effective procedure utilized for the assessment of meniscal injuries in the zone of low resources, however, MRI is costly and reachable to few ones. Keywords: Magnetic resonance imaging (MRI), meniscal tears, high resolutions ultrasounds (HRUS).
