Abstract
The menisci are essential for knee joint stability and function. Magnetic resonance
imaging (MRI) has proven to be an invaluable tool for evaluating a wide range of meniscal
injuries, yet various injury patterns are underdiagnosed or misdiagnosed, potentially
leading to persistent clinical symptoms and early joint degeneration. Additionally,
these pathologies may be difficult to recognize both clinically and during arthroscopy.
This review highlights commonly missed diagnoses, arranged in descending order of
how frequently they are misinterpreted in routine practice: medial meniscocapsular
junction tears, posterior root tears of the lateral meniscus, posterior horn tears
of the lateral meniscus, lateral meniscocapsular junction tears, and posterior root
tears of the medial meniscus. We also delve into relevant anatomy, normal MRI appearances,
injury findings and patterns, differential diagnoses, and tips for image interpretation.
By understanding these commonly missed injuries and using a targeted search strategy,
radiologists can enhance diagnostic accuracy and improve patient care.
