Validity of Magnetic Resonance Imaging Report of Meniscal Tear in Relationship to Arthroscopic Findings

Abstract

Objective: To determine the diagnostic accuracy of magnetic resonance imaging in assessment of meniscal tear taking arthroscopy as gold standard

Methodology: This cross-sectional study including 180 participants from different age groups was conducted at Shifa international hospital, Islamabad from June 2021- December 2021. Patients underwent both MRI and Arthroscopy and the results were compared. Data analysis was done using SPSS 22, quantitative variables were represented as mean and standard deviation, for qualitative variables frequencies and percentages were used for representation. Sensitivity, specificity, NPV, PPV and diagnostic accuracy of MRI was determined taking Arthroscopy as gold standard. For data analysis SPSS version 22 was used and the results were depicted using frequencies and percentages.

Results: 180 participants were included in the research out of which males were predominant with more than ¾ of the study population. Trauma and sports were the common cause of injuries. Sensitivity and specificity were found to be 95.95% and 69.13% respectively. PPV and NPV were 62.91% and 86.20% respectively. Patients were categorized in three groups with respect to age: middle aged (31-60 years) patients were greater in number and comprised more ¾ of the total.

Conclusion: MRI is a good, accurate non-invasive modality for the patients with meniscal tears while arthroscopy Still remains a gold standard.
