Abstract

Objective: Describe the characteristics of magnetic resonance imaging (MRI) 3.0 Tesla of traumatic meniscus tear and determine the value of 3.0 Tesla MRI in the diagnosis of traumatic meniscus tear compared with laparoscopic surgery. Methods: This is a cross-sectional, retrospective study. All patients clinically were diagnosed with traumatic meniscus tear at Military Hospital 175 from January 2022 to December 2022. Results: 119 cases. Men account for 65.5% and women account for 34.5%, mean age was 39.4 ± 14.3 years old (ranging from 12 to 74). There were only 70 cases where the cause of injury was investigated in which Domestic accidents accounted for the highest rate (38 cases, accounting for 48.6%). The rates of medial meniscus tear, lateral meniscus tear and both meniscus tears  were 46.2%; 35.2% and 7.6% respectively. The rate of tearing of the posterior horn is the highest, followed by the anterior horn and  body. Longitudinal tears were the most common type, accounting for 40% in medial meniscus tear 43% in lateral meniscus tear. The sensitivity, specificity, and accuracy of MRI for lateral meniscus tear were 80.0%, 80.4%, and 82.3%, respectively. The positive predictive value and negative predictive value were 66.7% and 90.9%, respectively. The sensitivity, specificity, and accuracy of magnetic resonance imaging for medial miniscus tear were 91.3%, 82.2%, and 85.7%, respectively; the positive predictive value and negative predictive value were 76.4% and 93.7%, respectively. Conclusion:  MRI  of the knee at 3.0 T is sensitive and specific compared with arthroscopy in the detection of meniscal tears, provides detailed information to help surgeons plan treatment strategies.
