Correlation Of Findings Of Mri With Arthroscopic Findings In Internal Derangement Of Knee Joint – A Study

Abstract

The aim of this study is to compare and correlate magnetic resonance imaging (MRI) and arthroscopic findings in cases of ligament injuries. MRI is currently available means of diagnosis in acute injured painful knee were clinical examination is non conclusive. Because of high negative value and exclude arthroscopy. The purpose of study was to correlate results of MRI in internal derangement of knee with arthroscopy findings, so as to determine the efficacy of MRI in different intrarticular knee injuries. Aim & Objective of study  To observe sensitivity and specificity of MRI in detecting cruciate ligament tears, confirmed subsequently with arthroscopy.  To observe the sensitivity and specificity of MRI in detecting meniscal tears.  To categorize discrepancies in finding of menisci and cruciate ligament between arthroscopy and MRI. Methods Of Collection Of Data  All patients who are clinically suspected of internal derangement of knee presented in department of orthopedics will be evaluated with clinical history and MR imaging in Radio diagnosis dept.  A surface coil is used, MRI will be performed using a 1.5 tesla MRI scanner (Philips MRI System ).Axial, coronal & sagittal T1 ,T2 ,PD & STIR images will be taken.  Strykararthroscope. xv Result Out of total 33 patients evaluated, most common injury were ACL and PCL injury least Common. Medial meniscus injury is most common than lateral meniscus and grade II & III common in both.MCL outnumbered LCL tear. Osseous lesion & joint effusion were most common associated with injuries. On arthroscopy most of findings correlated very well, however with ACL mid-substance & inferior surface of medial meniscus showed negativepredictive value. Conclusion MRI is non invasive and reliable investigation for ligament pathologies, It helps in accurate diagnosis of ligament injuries, there by helping in proper management by conservative and surgical treatment. However arthroscopy still remains gold standard for diagnosis and treatment of the same. False negative cases have been reported in meniscal injuries. So, MRI can be helpful to diagnose the knee injuries reducing there by invasive procedure and assist further management.
