abstract
Background: Knee pain is a common complaint that affects people of all ages. Knee pain may be the result of an injury which can affect any of the ligaments, tendons or fluid-filled sacs bursa that surround knee joint as well as the bones, cartilage and ligaments that form the joint itself. MRI Provides excellent soft tissue contrast and is capable of evaluating soft tissue and bony structures in multiple imaging planes which provides signi ficant advantages over other imaging techniques, MRI have also been demonst rated as a cost effective Technique by reducing unnecessary surgical and Arthroscopic interventions. It is regarded as the top imaging and diagnostic tool for the knee joint as a re sult of its ability to evaluate a wide range of anatomy and pathology varying from l igamentous injuries to articular cartilage lesions Aim of the Study: The aim of the study is to evaluate the role of MRI in evaluation of patients with Traumatic and Non-Traumatic Knee Pain. Materials and Method: 30 patients were included in the study, from them 10 patients were excluded according to the Exclusion criteria and 20 patients were included according to the inclusion criteria (6 females (30%) & 14 male (70%). The age of the patients is 21-63 years.The study was done in Baqubah Teaching hospital /Diyala /Iraq from November 2020 till October 2021. Result: This study shows that Among the 40 patients who had knees pain, 30 of them, their pain were due to traumatic causes (75%), and the other 10 due to non_traumatic causes (25%). Meniscus injuries founded in 28 patients, (70.00%) of total, 20 patients of them(71.43%) due to trauma and other 8 patients(28.57 %) with out history of trauma. Anterior cruciate ligament injuries appeared in 18 cases (45.00% of total), 8 of them (44.44%) had sprained Anterior cruciate ligament, 6 (33.33%) had partial Anterior cruciate ligament tear, and 4 (22.22%) had complete tear. Bone Morrow contusion appeared in 12 cases (30.00%). 10 of them (83.33 %) with traumatic history and other 2(16.67 %) without. Joint effusion detected in 24 patients about (60.00%) of total cases that seen in our study Conclusion: MR imaging is the best imaging modality for diagnosis of different knee lesions and can be considered as replacing of other invasive modalities for diagnosis of different knee lesions and the best plane and pulse sequence for each injury was as following: Sagittal PD FSE sequence for appreciation of the Anterior cruciate ligament, posterior cruciate ligament posterior cruciate ligament and the extensor mechanism tendons,Coronal & Sagittal PD fat suppressed sequence for menisci., PD fat suppressed sequence for menisci, collateral ligaments and articular cartilage and T2W images help in demonstration of joint effusion.
