Aims and objectives: To study the spectrum of MRI findings in suspected cases of Meniscal and cruciate ligament injuries in knee joint .To correlate the MRI findings with arthroscopic findings and determining the accuracy of MRI in diagnosing knee injuries. Materials and method: This analytical cross-sectional study was carried out in the department of Radiology and imaging in collaboration with department of Orthopaedics , ASRAM Medical college and Hospital, Eluru, during the period of May 2022 to March 2023. MRI of knee joint was performed using 1.5 Tesla MRI scanner, Seimens magnetom avento syngo (MR D- 13) 16 channel machine on 100 patients referred for evaluation of meniscal and cruciate ligament injuries in traumatic knee joint with arthroscopic correlation . Results: Males commonly encounter knee injuries (82%).Age groups between 20-30 years were injured more (46%).Complete tears of ACL were more common ( 59.4%).Sensitivity and specificity for detection of tears by MRI were found to be 94.74%and 90.32% for Medial meniscus tears and 90.91% and 97.4% for lateral meniscus tears and for ACL tears 97.1% and 86.6% and PCL tears 87.50% and 98.00%.MRI is accurate in evaluation of cruciate ligament and meniscal injuries of knee joint with accuracy rate of 94% for ACL ,98% PCL ,92% for Medial Meniscus and 96% Lateral Meniscus. Conclusion: MRI is highly sensitive and accurate in identification of both ACL ,PCL tears and Medial and lateral meniscus tears . A close correlation was observed between MRI and arthroscopic diagnosis.
