A comparative study of magnetic resonance imaging and arthroscopy in internal derangement of knee
Journal Title: Indian Journal of Orthopaedics Surgery - Year 2018, Vol 4, Issue 2
Abstract
The purpose of this study is to compare the findings of magnetic resonance imaging with arthroscopy in internal derangements of knee and to assess the sensitivity specificity and accuracy of magnetic resonance imaging in comparison to arthroscopyMethods and Materials Fifty six patients with history of suspected internal derangement of knee were evaluated prospectively with MRI and compared with arthroscopy during a one and half a year period from January 2016 to June 2017 at Katuri Medical College Hospitals Chinakondrupadu Guntur 15 Tesla MRI machine using a closed extremity coil is used Commonly used sequences in MRI of the knee include Turbospin echo TSE FFE Gradient echo and Short Tau Inversion Recovery STIR sequences in Axial Sagittal and Coronal planes using a slice thickness of 3 mm with a 03 mm slice gap Arthroscopy of the knee with standard anteromedial and anterolateral portals with the patient in supine position done in all the casesObservations The diagnostic sensitivity specificity and accuracy of MRI in detecting cruciate ligament and meniscal injuries as compared to arthroscopy is as follows Anterior Cruciate Ligament ACL 9729 8947 9464 Posterior Cruciate Ligament PCL 100 100 100 Medial Meniscus MM 100 9333 9821 and Lateral Meniscus LM 9310 9259 9285 Most common lesions found were ACL and Medial Meniscal tears posterior horn of MM being the most common siteSummary and Conclusion MRI is a useful noninvasive modality having high sensitivity specificity and accuracy in diagnosing cruciate ligament and meniscal injuries MRI should be considered as the first line of investigation in all patients with suspected internal derangements of knee MRI being easily available and noninvasive is useful as a preoperative screening modality thus improves the quality of diagnostic and therapeutic arthroscopies and further reduces the morbidityArthroscopy is the gold standard in diagnosing cruciate ligament and meniscal injuriesKeywords Arthroscopy MRI
