Objective: The aim of this study was to compare accuracy of clinical examination and MRI taking Arthroscopy as Standard in knee injuries. Materials and Methods: We evaluated 198 patients retrospectively in 1.5-year period from January 2013 to June 2014 with a meniscal tears and ligament tears. The participants were subjected to clinical examination, MRI and then Arthroscopy. The results were compared and analyzed using various statistical tests. Results: Diagnostic accuracy of MRI was 62.62% for medial meniscus and 89.89% for lateral meniscus. Grade 1 and 2 meniscal tears have low sensitivity 50% as compared to Grade 3 and 4 with 88.13%. In the case of ACL tears, diagnostic accuracy for clinical examination and MRI examination came out to be 88.38% and 89.39% respectively. Conclusion: We can avoid diagnostic arthroscopy in patients with ACL and PCL injuries having equivocal clinical and MRI examination and go on for therapeutic modality. In case of meniscal injuries graded as 1 and 2 on MRI, are rarely seen on arthroscopy hence arthroscopy is not requiredfor these meniscal injuries.
