Abstract
Objectives: To compare the diagnostic efficacy of Magnetic Resonance Imaging (MRI) with arthroscopy in detecting Anterior Cruciate Ligament (ACL) and meniscus tears by evaluating the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of MRI.
Methods: A prospective observational study was conducted on 120 patients exhibiting clinical signs of ACL or meniscus tears. All patients underwent MRI followed by arthroscopy, which served as the gold standard for diagnosis. Statistical measures, including sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of MRI, were calculated.
Results: MRI demonstrated high sensitivity (95.5%), specificity (83.3%), and accuracy (92.5%) for diagnosing ACL tears, while meniscus tears showed a sensitivity of 84.2%, specificity of 79.5%, and accuracy of 82.5%.
Conclusion: MRI is a valuable non-invasive diagnostic tool for ACL and meniscus injuries, offering high accuracy in most cases. However, it has limitations in detecting partial ACL tears and complex meniscal injuries. Arthroscopy remains the definitive diagnostic and therapeutic procedure.
