Abstract: (6435 Views)
Background and Objectives: Knee joint as the largest synovial joint in the body, consists of the lateral collateral ligament, cruciate ligament, and medial and lateral meniscus. For proper management, identification of damage to any structures of the knee is necessary. In this study, snsitivity, specificity, and diagnostic accuracy of high resolution CT scan in meniscal lesions, were assessed.
Methods: In this test accuracy assessment study, 57 patients with a history of positive meniscus lesion, who referred to Ayatollah Mousavi Hospital of Zanjan city from 2015 to 2016, were investigated by magnetic resonance imaging, high resolution computed tomography, and arthroscopy. Magnetic resonance imaging and high resolution computed tomography data, were compared to knee arthroscopy as the diagnosis gold standard. Kappa (κ) correlation coefficient was used to calculate the consistency of the tests.
Results: Out of the 57 patients presented with meniscal lesion, 52 patients (91.2%) were male and 5 patients (8.8%) were female. The highest incidence of meniscal lesions was in ages from 21 to 30 years. Among the causes of meniscal lesions, exercise with prevalence of 47.9%, was the most prevalent cause of injury. In comparison with arthroscopy, the sensitivity, specificity, and accuracy of high resolution computed tomography were determined to be 64.7%, 55%, and 60%, respectively, and for magnetic resonance imaging were 85.2%, 50%, and 77.5%, respectively.
Conclusion: According to the results of the present study, specificity, sensitivity, and accuracy of high resolution computed tomography in the diagnosis of meniscal lesions, was lower than the previous studies.
