Abstract

Background: The diagnostic accuracy of magnetic resonance imaging (MRI) for meniscal tears has not been adequately investigated, although it has been utilized extensively. By contrasting MRI results with arthroscopy findings, we hoped to gauge MRI's diagnostic precision.
Objectives:   Investigating the incidence of ACL and meniscal tears; establishing a correlation between arthroscopy and MRI findings by calculating the specificity, sensitivity, positive and negative predictive values (with arthroscopy highly esteemed); grading the degree of subluxation; and ascertaining the minimal quantity of fluid that ought to be present in the knee.
Materials and Methods:  The MRI of forty patients in the age range of twenty to forty years old and twelve arthroscopic correlations was evaluated in the year 2021-2022.
Results:  In percentage form, the sensitivity, specificity, PPV, and NPV were calculated. For MM, the ACL results were 87.87, 81.57, 80.55, and 88.57, whereas for LM, they were 77.77, 81.81, 72.41, and 85.71. One patient had anterior tibial subluxation, which accounted for 35.6% of all cases. Joint fluid was seen in 201 cases when the suprapatellar pouch appeared laterally with internal disruption.
Conclusion:  Patients with ACL injuries should be carefully evaluated during arthroscopy since preoperative MRI has a limited diagnostic accuracy.
