Assessment of the Accuracy of Magnetic Resonance Imaging MRI in Posterior Horn Lateral Meniscal Tears in Correlation with Clinical Stability and Arthroscopy.

This article, published in Seminars in Musculoskeletal Radiology, aims to assess the accuracy of magnetic resonance imaging (MRI) in diagnosing tears of the posterior horn of the lateral meniscus (PHLM) in correlation with clinical stability and arthroscopy. The study included 41 patients with surgically verified PHLM tears, and the MRI scans were initially reviewed by radiologists without specialization in musculoskeletal imaging. The results showed that radiologists without musculoskeletal imaging experience only detected 45.2% of the PHLM injuries, while radiologists with musculoskeletal imaging experience detected 85.7% of the injuries. The most commonly missed injuries were root avulsions and tears close to the root of the lateral meniscus. This study highlights the importance of specialized radiologists in accurately diagnosing PHLM tears. [Extracted from the article]
