Background: MRI is radiation free modality and has ability to understand the soft tissue, anatomy and musculoskeletal system pathologies. MRI has the advantage of demonstrating the cartilages, bones, soft tissue in detail. Objectives of current study were evaluation of ligaments and meniscal injuries using magnetic resonance imaging, to study the pattern and spectrum of knee injuries in relation to mechanism of injury and to correlate MRI findings with that of arthroscopic findings. Methods: All the MRI studies were done using a 1.5T MRI scanner (Siemens Magnetom) in our department, department of radiodiagnosis, ACS medical college, Chennai. Patient taken up for arthroscopy and the arthroscopic findings were collected. The data of MRI collected was compared with arthroscopy findings. Results: On correlation of the overall findings the sensitivity of MRI versus arthroscopy was 90.62% Specificity was 84.55% positive predictive value was 92.06%, negative predictive value was 80.00% Between them with a kappa 0.059 Conclusions: MRI of knee is considered efficacious especially in the setting of indeterminate clinical finding and can stratify patients, thereby increasing the diagnostic confidence of the clinicians leading to appropriate surgical planning and management.
