Abstract

Background: Complete evaluation of knee injury includes a detailed history, thorough clinical examination, radiological evaluation, and arthroscopic examination.  Present study was aimed to study correlation between MRI and arthroscopic findings in anterior cruciate ligament and meniscal injuries of the knee joint at a tertiary hospital.
Material and Methods: Present study was hospital based, prospective, comparative, observational study, conducted in ppatients admitted to the hospital with traumatic knee injury, underwent MRI knee followed by arthroscopy.
Results: During study period 60 patients of knee injury underwent MRI knee followed by arthroscopy considered for study. Majority were male (86.67 %), from 20-29 years age group (60 %), had injury dure to motor vehicle accident (43.33 %) & sports related activity (35 %). We compared injuries to ACL, PCL medial meniscus & lateral meniscus mentioned during MRI study with respect to knee arthroscopy using knee arthroscopy as diagnostic gold standard. In cases of ACL tear, MRI had sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) & accuracy values as 86.66 %, 73.33 %, 90.69 %, 64.70 % & 83.33 % respectively. In cases of PCL tear, MRI had sensitivity, specificity, PPV, NPV & accuracy values as 86.36 %, 89.47 %, 82.60 %, 91.89 % & 88.33 % respectively. In cases of Medial meniscus tear, MRI had sensitivity, specificity, PPV, NPV & accuracy values as 86.11 %, 87.5 %, 91.17 %, 80.76 % & 86.66 % respectively. In cases of lateral meniscus tear, MRI had sensitivity, specificity, PPV, NPV & accuracy values as 83.33 %, 88.09 % & 75 %, 92.5 % & 86.66 % respectively.
Conclusion: MRI is an excellent, non-invasive, radiation free imaging modality with multiplanar capabilities and excellent soft tissue delineation
