BACKGROUND
The aim of the study is to evaluate the diagnostic value of MRI in the diagnosis of acute and chronic anterior cruciate ligament tears.
MATERIALS AND METHODS
A retrospective analysis of MRI findings in 331 patients with knee joint injuries was done in a period of 18 months. MRI examination was performed on 1.5 T applying standard protocols (FSE proton density sagittal, SE coronal T2 fat suppression sequence, SE proton density axial with fat suppression). All patients had preliminary plain radiographs of knee joints also. Arthroscopy correlation was done in patients who have significant tears.
RESULTS
We reviewed the various imaging features of ACL tears on MRI examination and their significance with clinical correlation. Out of 331 cases, 122 (36.8%) have varying types of ACL injuries.
CONCLUSION
ACL injuries are more common in males in the present study with peak age incidence of 20-30 years. Cases of ACL tears-36.8% (122 out of 331). Sex ratio=M:F=308:23=13.4:1.
