MRI Evaluation of Acute Internal Derangement of Knee
ABSTRACT
Introduction: Internal derangement of the knee is a blanket term used to cover a group of disorders involving destruction of the normal functioning of the ligaments or cartilages. MRI provides excellent soft tissue contrast and is capable of evaluating the soft tissue and bony structures in multiple imaging planes which provide significant advantage in IDK. Methods and Materials: A prospective study of hundred twenty patients who underwent MRI for the diagnosis of internal derangement of knee between the period January 2013 and January 2015 was conducted. All the patients gave a history of knee joint pain following trauma and clinically suspected to have meniscal and ligament tears. Patients were evaluated using Philips intera R 11 1.5 T with pulsar gradient system using a sensor extremity coil. Results: Commonest lesion detected in our study was ACL tear followed by meniscal tear and medial collateral ligament injury. The most common sign of cruciate ligament injury was hyper intensity in the ligament. Grade 3 was the most common grade of meniscal tear. Conclusion: MRI is unique in its ability to evaluate the internal structure as well as the surface of the meniscus. Many anatomical variants can mimic a tear on MRI. MRI is an excellent non invasive modality for imaging the knee.
