Correlation of Mri vs Arthroscopic Correlation of Internal Derangement of Knee (Idk)

Abstract

PURPOSE: It is to prove the validness of MRI in diagnosing the internal structural pathology in IDK with confidence compared to gold standard arthroscopy. MATERIALS AND METHODS: Ours is prospective study. We took arthroscopy as gold standard and took systematic review of MRI and arthroscopy in diagnosing IDK in 54 pts. RESULTS: MRI is 100% sensitive in diagnosing ACL PCL, meniscal injuries and hence the best screening tool. But many of grade 1/2 tears of meniscal tears in MRI are normal at arthroscopy. Majority of false positives occur in posterior horn of lateral meniscus.
