A study on spectrum of MRI findings in traumatic knee

Abstract

MRI has emerged as an excellent modality for imaging of ligaments, cartilage, menisci and other structures around the knee joint. This is due to the combination of multiplanar capability and superior soft tissue characterization. This modality has superseded already available modalities like radiograph and CT, over last two decades. A prospective study consisting of 50 patients with traumatic knee joint was undertaken to study the spectrum of MRI findings in all consecutive cases of knee trauma referred from orthopedic OPD. Out of 20 patients with isolated medial meniscus tear, the posterior horn was commonest site of involvement occurring in 11 patients (55%) and the predominant type of tear was horizontal and oblique that occurred in 7 patients each (35%). Grade III tear were the commonest seen in 12 patient (60%) followed by grade II in 8 patients (40%).
