Abstract :

Knee injuries are conventionally assessed clinically and subjected to radiographs for diagnosis.The use of arthroscopy improves the accuracy of diagnosis and simultaneously can provide therapeutic intervention to treat the underlying derangement.Now a days MRI of the knee has been regarded as the non–invasive alternative to diagnostic arthroscopy.Objectives–To assess the ligamentous and meniscal injuries of knee using MRI and to detect the reliability of MRI in detecting meniscal tears and cruciate ligament tears by calculating Sensitivity,Specificity,Positive predictive value(PPV),Negative predictive value(NPV) and Accuracy.Method–A one year prospective cross–sectional study from January 2014 to Feuary 2016 was performed on 100 Patients who came to Orthopaedics department of NRS Medical College with history of knee injury and subsequently underwent MRI and Arthroscopy of knee for suspected internal derangement.Results–The Sensitivity,Specificity,PPV,NPV and Accuracy of MRI were respectively– 91.8%,90.2%,90%,92% and 91% for medial meniscus(MM) tear; 87.5%,96.5%,82.3%, 97.6% and 95% for lateral meniscus(LM) tear; 86.1%,89.1%,81.6%,91.9% and 88% for Anterior cruciate ligament(ACL) tear; 87.5%,97.8%,77.8%,98.9% and 97% for Posterior cruciate ligament(PCL) tear.Conclusion–MRI is an accurate non–invasive modality for the assessment of meniscal and ligamentous injuries of knee.
