Prevalence of abnormalities detected by magnetic resonance imaging (mri) in patients with knee trauma at a tertiary care teaching hospital of southern rajasthan

Background: Magnetic Resonance Imaging (MRI) is the most commonly used imaging modality in the evaluation of knee injuries. So, this study was planned to use MRI in determining the incidence of knee lesions in traumatic knee patients and their relation with the age and sex of the patients. Materials and Methods: This prospective study was performed for a period of 1 year after taking the permission from institutional ethics committee in a tertiary care teaching hospital. Patients referred to the Department of Radiology with post traumatic knee joint symptoms were recruited. Patients’ socio-demographic data, clinical history and physical examination findings were recorded to correlate the findings. MRI Acquisition Knees were imaged by using Siemens Avanto MR machine with a superconducting magnet and field strength of 1.5 tesla using dedicated knee coil (Flex). Results: Total 63 patients were examined by MRI and the most common age group was found to be 21-30 years. 88.89% knee lesions were found in male. Joint Effusion was found to be most frequent lesion in symptomatic knee constituting 94.64%. Amongst the ligament injury, ACL was found be highest approximately 50% in patients with complete tear in 57.14%. Amongst the menisci injury medial meniscus injury was found be highest approximately 72.72 % with grade III in 43.75%. Conclusion: MRI was found to be good diagnostic tool for evaluation of traumatic knee lesions.
