MRI Evaluation of Internal Derangements of Knee Joint
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 3
Abstract
Background- The knee is one of the most commonly involved joint in the external injuries. Internal derangement of knee (IDK) joint is a common cause of morbidity in the young, active individuals like athletes. The most widely used investigations are arthroscopy and Magnetic Resonance Imaging (MRI). Arthroscopy is considered as the gold standard for diagnosis of traumatic intra-articular lesions, however, it is an invasive procedure requiring hospitalization and anaesthesia and is associated with complications. Hence Magnetic Resonance Imaging (MRI) has now been accepted as the best imaging modality for noninvasive evaluation of knee injuries. This study has been done to know the pattern of distribution of different types and incidence of injuries in traumatic knee joint by MR imaging and to compare with arthroscopy or arthrotomy findings. Aim- a) To evaluate the pattern of distribution of ligamental and mensical injuries using Magnetic Resonance Imaging (MRI) b) To find the proportion of cases where the MRI findings agree with arthroscopy or arthrotomy findings. Materials and Methods- 69 Patients who undergo MR imaging of the knee on the advice of the referring doctor on his suspicion of internal derangement of the knee (IDK) in the department of Radiodiagnosis served as the subjects for this study from january 2013 to june 2014. Arthroscopy was carried out in OT by orthopedic surgeons in selected and available cases for diagnostic or therapeutic purposes. Findings of MRI of the Knee are correlated with the arthroscopic findings in patients with internal derangements of knee. Results- Qualitative data is described in terms of percentage from the 69 patients with suspected internal derangement of knee joint evaluated with MRI with assessment of 95% confidence interval and in selected cases proportion of agreement with the arthroscopy or arthrotomy is obtained. Conclusion- MRI is a noninvasive, useful, noninvasive, radiation free & reliable diagnostic tool for evaluating knee injury and it should be done in suspected menisci and ligamentous injury, to be posted for arthroscopy, thus preventing unwanted diagnostic arthroscopy
