    Magnetic resonance imaging (MRI) is considered highly useful in the diagnosis of knee lesions. Most diagnostic studies comparing MRI and arthroscopy have shown good diagnostic performance in detecting lesions of the menisci and cruciate ligaments. Nevertheless, arthroscopy has remained the reference standard for the diagnosis of internal derangements of the knee, against which alternative diagnostic modalities should be compared.

    In this study, researchers took arthroscopy as the ‘gold standard’, and undertook a systematic review of MRI and arthroscopy in the diagnosis of internal derangements of the knee. Researchers used Coleman scoring methodology to identify scientifically sound articles in a reproducible format.

    Upon review, researchers found MRI to be highly accurate in diagnosing meniscal and anterior cruciate ligament (ACL) tears, and declared it the most appropriate screening tool before therapeutic arthroscopy. It is preferable to diagnostic arthroscopy in most patients because it avoids the surgical risks of arthroscopy. The results of MRI differ for medial and lateral meniscus and ACL, with only 85% accuracy.
