Abstract

Background: The role of magnetic resonance imaging has steadily increased and now it has become the first line investigation for most of the lesions of knee. It is also being used for pre and post operative evaluation. Present study was aimed to study ligament and meniscal injuries following knee trauma and their radiological diagnosis. Material and Methods: Present study was single-center, prospective, observational study, conducted in patients with clinically suspected internal derangement of knee following trauma to knee, underwent MRI study at our hospital. Results: In present, among 97 patients, majority were from 21-30 years age group (31.96 %) followed by 31-40 years age group (23.71 %). Mean age was 32.31 ± 10.15 years.. Male (61.85 %) outnumbered female (38.15 %). In present study ACL tear was noted in 36 patients (37.11 %), majority had complete ACL tear (72.22 %). PCL tear was noted in 3 patients (66.67 %), majority had partial PCL tear (66.67 %). In present study MCL tear was noted in 25 patients (25.77 %), majority had grade I tear (64 %). LCL tear was noted in 10 patients (10.3 %), majority had grade I tear (60 %). MM tear was noted in 58 patients (59.79 %), majority had grade III tear (51.73 %). LM tear was noted in 10 patients (10.3 %), majority had grade II/III tear (40 %). Joint effusion was present in 57 cases (58.76 %). In present study osseous or other injuries were noted in 48 patients (49.48 %). Arthroscopy was done in 23 patients (23.71 %). MRI Arthroscopy correlation was noted in 19 patients out of 23 patients (82.60 %). Conclusion: MRI is valuable diagnostic tool for evaluation of pathology of knee joint and is recommended investigation to make decision for further management of patient. Additional to ligamentous injuries, bony injuries can be evaluated simultaneously.
