Comparison Of Clinical Examination, MRI And Arthroscopy In Knee Injuries.

Objective: To compare accuracy of clinical examination and MRI taking Arthroscopy as Standard in knee injuries. Patients and Methods: 60 patients with knee injury were subjected to clinical examination, MRI and then Arthroscopy. The results were compared and analysed using various statistical tests. Results: Diagnostic accuracy of MRI was 66.67% for medial meniscus and 90% for lateral meniscus GR 1 and 2 meniscal tears have low sensitivity 50% as compared to GR 3 and 4 with 88%. In the case of ACL tears, diagnostic accuracy for both clinical examination and MR examination came out to be 90% 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 required for these meniscal injuries.
