Abstract

The use of Magnetic Resonance Imaging (MIR) as a diagnostic trial in the pathology of the knee, has become an important non invasive alternative. We have designed a double blind protocol with the Department of Radiology through we have evaluated 31 patients analyzing the MRI results in relation with the arthroscopic findings. For the medial meniscus, the accuracy of the MRI was 93 % and 87% for the lateral. As main conclusions, the sensibility was 90% for the medial meniscus and 75% for the lateral one and about specificity, we found a result of 100% for the medial meniscus and 91% for the lateral. The negative and positive predictive values were respectively 85% and 100% for the medial and 84% and 75% for the lateral. We noted more diagnostic difficulties in the anterior portion of lateral meniscus and lack of precission in the determination of the type and extension of the meniscal injury.
