MRI Diagnosis of Meniscus Tears in the Knee: An Updated Systematic Review and Meta-analysis

Listen to this summary

The authors aimed to update the diagnostic performance benchmarks of MRI for detecting meniscus tears in the knee compared to arthroscopy, analyzing factors that influence accuracy. Their systematic review and meta-analysis of 75 studies revealed that MRI sensitivity was higher for medial meniscus tears, while specificity was greater for lateral tears, with certain imaging criteria enhancing diagnostic performance. Overall, the study confirmed consistently high accuracy for knee MRI in diagnosing meniscus tears across various study designs.
