Abstract
The objective of this study was to evaluate the role of magnetic resonance imaging (MRI) as a screening procedure before arthroscopy of meniscal tears. Forty-one knees in 40 patients underwent MRI and arthroscopy. Compared with arthroscopy, the sensitivity, specificity, positive predictive value and negative predictive value for MRI for the medial meniscus were 100%, 77%, 71% and 100%, respectively, while the values for the lateral meniscus were 40%, 89%, 33% and 91%, respectively. The overall accuracy for MRI of the medial and lateral menisci combined was 84%. On the basis of the high predictive value of negative MRI, we conclude that MRI is useful to exclude patients from unnecessary arthroscopy.
