This study aims to evaluate the diagnostic value of magnetic resonance imaging in diagnosing anterior cruciate ligament and meniscus tears. Methods: This was an observational cross-section study conducted at a tertiary-level hospital in Nepal. The patients operated on for anterior cruciate ligament and/or meniscus tear were considered for the study. The accuracy of magnetic resonance imaging was calculated by comparing its findings with those in arthroscopy. Results: The total number of cases were 134. The sensitivity and specificity were as follows: medial meniscus 88.81%, 95.10%; lateral meniscus 57.12%, 95.14%; anterior cruciate ligament 96.12%, 75%. The sensitivity and specificity of the injuries for 3 Tesla vs 1.5 Tesla Magnetic Resonance Imaging were as follows: medial meniscus 89.20%, 97.84% vs 87.52%, 87.52%; lateral meniscus 65.25%, 100% vs 30%, 90.91%; anterior cruciate ligament 96.12%, 75% vs 96.12, 75%. Conclusions: The sensitivity of magnetic resonance imaging in diagnosing anterior cruciate ligament injury was higher while specificity was higher for lateral meniscus injury. The study also showed that 3 Tesla was better than 1.5 Tesla magnetic resonance imaging in diagnosing meniscus injury.en-USArticle
