Background: Magnetic resonance imaging is a very useful diagnostic tool for the detection of abnormalities of injured knee joint. Objective: This present study was performed to see the different abnormalities of injured knee joint detected by MRI among adult patients. Methodology: This cross-sectional study was conducted in the Department of Radiology and Imaging at Bangabandhu Sheikh Mujib Medical University (BSSMU), Dhaka, Bangladesh from January to June 2021 for a period of six months. The patients in the age group of equal or more than 18 years with both male and female who were visiting Department of Orthopaedics at BSMMU, Dhaka with history of knee injuries were subjected to MRI were selected as study population.
