The Accuracy of Magnetic Resonance Imaging Compared with Arthroscopic Finding in Intra-articular Traumatic Knee Injury

The purpose of this study was to assess the correlation among Magnetic Resonance Imaging (MRI) report and arthroscopic finding in 36 cases with intra-articular traumatic knee injury who had been referred to arthroscopic clinic at Kerman Medical Sciences University. Overly, the accuracy rate was 66.6%, sensitivity 91% and specificity 22%. The accuracy, sensitivity, specificity, positive and negative predictive values were, respectively 72.2, 100, 61.5, 50 and 100% for medial meniscus tear and 88.8, 80, 92.3, 80 and 92.3% for lateral meniscus tear. There were two cases with anterior cruciat ligament rupture that its accuracy was 100%. Present results showed that MRI is a safe and useful adjunct to the clinical examination of the injured knee and an aid to efficient preoperative planning.
