“…We had sensitivity for medial meniscal tears of 80%. In the literature the sensitivity for medial meniscal tears decreases to 84-88%, while the sensitivity of diagnosing lateral meniscal tears decreases to 68-83% in the setting of a concurrent ACL injury [2,16]. Our sensitivity of 55% for lateral meniscal tears was lower than that reported in the literature.…”

“…Medial meniscal tears are more common with chronic instability, however, because of the secondary restraining effect of the medial meniscus to anterior tibial translation [1,9]. For medial meniscal tears, sensitivities have ranged from 86% to 96% and specificities from 75% to 94%; respectively, values for lateral meniscal tears have been 64-89% and 87-98% [2,6,16].…”

This study compares MRI with examination under anaesthesia to surgical findings in evaluating soft tissue injuries in acute multi-ligament knee trauma. Preoperative MRI was done for 44 patients who underwent surgery for grade III ACL and grade III medial collateral ligament (MCL) injury. In 21 cases both ACL and MCL were treated surgically, but in 23 only ACL. Intra-operative and MRI findings were compared. Accuracy of MRI for medial meniscal tears was 88.6%, sensitivity 80%, and specificity 91.2%; accuracy for lateral meniscal tears was 72.7%, sensitivity 55% and specificity 87.5%. Accuracy and sensitivity for severity of ACL tear was 93.2% and of MCL tear 86.4%. In 88.6% of the knees, bone bruises were visible, with anterolateral femoral and posterolateral tibial bone bruise being the most common. MRI revealed no chondral lesion, but arthroscopy revealed 11. In combined ACL-MCL ruptures, the incidence of concomitant injuries is high and the injuries are best detected with MRI.

“…ACL injuries were commonly associated with medial meniscal tears, medial collateral ligament injury, lateral femoral notch sign (Figure 3) and posterolateral tibial plateau contusions. These findings correlated with the findings in the studies of Berquist TH et al, 7 O' Donoghue DH et al, 8 Rubin et al 9 and Remer et al 10,11,12 PCL injury was uncommon and was found in 14% of the patients. Among these, complete ( Figure 4) and partial tears accounted for 50% of the PCL injuries.…”

BACKGROUNDInternal derangement of knee means loss of normal knee function due to ligament or meniscal injuries. MRI is a routinely utilised noninvasive modality for evaluation of various knee disorders including internal derangement. MRI provides excellent soft tissue contrast and multiplanar images when compared to other musculoskeletal imaging modalities.The aim of the study is to study the demographic profile of patients presenting with internal derangement of knee, identify the various ligament and meniscal injuries causing internal derangement of knee and describe the MRI features of the ligament and meniscal injuries.

The aim of this study was to detect the accuracy of routine magnetic resonance imaging (MRI) done in different centres and its agreement with arthroscopy in meniscal and ligamentous injuries of the knee. We prospectively examined 70 patients ranging in age between 22 and 59 years. History taking, plain X-ray, clinical examination, routine MRI and arthroscopy were done for all patients. Sensitivity, specificity, accuracy, positive and negative predictive values, P value and kappa agreement measures were calculated. We found a sensitivity of 47 and 100%, specificity of 95 and 75% and accuracy of 73 and 78.5%, respectively, for the medial and lateral meniscus. A sensitivity of 77.8%, specificity of 100% and accuracy of 94% was noted for the anterior cruciate ligament (ACL). We found good kappa agreements (0.43 and 0.45) for both menisci and excellent agreement (0.84) for the ACL. MRI shows high accuracy and should be used as the primary diagnostic tool for selection of candidates for arthroscopy. Level of evidence: 4.
