MRI is an accurate, noninvasive imaging modality for evaluation of knee injuries, and determines the patient management, saving them from unnecessary arthroscopy. Our study focuses on the fundamental biomechanical forces underlying the most common injuries and correlate MRI findings with specific traumatic mechanisms. We conducted a retrospective study on 138 patients having prior history of knee trauma. The studies evaluated cruciate ligament tears, collateral ligament injuries, chondromalacia patella, bone marrow contusions, joint effusions, tendon tear, meniscal tear and osteoarthritis.
