ABSTRACT
Background: The various imaging modalities used to evaluate pathological conditions of the knee include conventional fluoroscopy, arthrography, radiography, sonography, computed tomography, nuclear medicine, and magnetic resonance imaging. However, magnetic resonance imaging (MRI) has been recognized as an efficient, non-invasive test for identifying meniscal tears and other knee diseases. The Aim of the study: To evaluate the internal derangements of ligaments of the knee in an acute traumatic knee setting and to identify their patterns in MRI. Materials and methods: A cross-sectional study of fifty cases where MRI was used as the diagnostic modality evaluating the internal derangement of the knee. The study period was May 2017 to November 2018. The study included patients with traumatic knee injuries. The studies were carried out with a 1.5 Tesla Philips MRI machine. Results: Majority of the participants having IDK had anterior cruciate ligament tear followed by medial menisci tear and lateral menisci tear while posterior cruciate ligament tear and lateral collateral ligament tear are not so much common. Conclusion: MRI is a beneficial and non-invasive modality which possesses higher diagnostic accuracy and better sensitivity. It might be advantageous in the clinical conditions where the arthroscopy may not useful for the inferior surface and peripheral meniscus tears. The results of this present study support that MRI can be very helpful in diagnosing the cruciate and meniscal ligament injuries. It can accurately detect, localize and distinguish various internal derangements of the knee joint with excellent soft tissue delineation and help in arriving at an accurate anatomical diagnosis thereby helping further management of the patients.
