Abstract

The knee is one of the most commonly injured joint. Knee injury is the second most common problem in the musculoskeletal system for which patients consult their general physician. In acute situations, radiographs can be very useful to diagnose or rule out fractures. A second category of patients’ have sub-acute or even chronic symptoms that may be related to trauma, overuse, degeneration, etc. The study population includes all the patients presenting with history of and /or clinical findings suggestive of knee trauma and use MRI for evaluation. The MRI is done on the advice of the referring doctor and no patient is made to undergo MRI knee for the sole purpose of this study. Posterior horn of medial meniscus was observed to be the most commonly injured. Vertical tear of medial meniscus was identified as the most common type of injury.
