Abstract: Background: Knee joint is one of the most commonly injured joints because of its anatomical structure, its exposures to external forces and the functional demands placed on it. Because of the difficulty of obtaining an accurate clinical examination in the acute setting, the incidence of such injuries is not well understood.
Objectives: To Compare Arthroscopic and MRI findings of Injured knee.
Methods: 30 Patients who reported with knee symptoms after knee injury, who were indicative of Internal derangement and underwent arthroscopy procedure following a detailed clinical examination and imaging with MRI
Results: Based on Clinical examination, ACL injury was seen in 50% of the cases, Medial meniscus tear was seen in 26.66% of the cases and lateral meniscus tear in 16.66% of the cases. Based on MRI, ACL injury was seen in 63.33% of the cases, Medial meniscus tear was seen in 50% of the cases and lateral meniscus tear in 30% of the cases. Based on Arthroscopy, ACL injury was seen in 76.66% of the cases, Medial meniscus tear was seen in 36.66% of the cases and lateral meniscus tear in 16.66% of the cases. The accuracy was 100% for ACL tear and Osteochondral defect was 100%. The accuracy was 86% for PCL and meniscal tears. The accuracy for lateral meniscal tears was 83%.
Conclusion: Arthroscopy is gold standard and finer when compared to MRI in the diagnosis of meniscal and cruciate ligament tears. MRI is a useful non-invasive modality having moderate sensitivity, specificity and accuracy in the diagnosis of menisci and cruciate ligament injuries.
