GARCIA LINAGE, Rubén; JEONG, Minseung  and  SAUCEDO MORENO, Eric Misael. Is there a correlation between findings by MRI and arthroscopy in knee meniscal lesions?. Acta méd. Grupo Ángeles [online]. 2021, vol.19, n.1, pp.35-39.  Epub Jan 31, 2022. ISSN 1870-7203.

In the detection of meniscal injuries, the clinic is useful and, as a supplementary study, it is suggested to use nuclear magnetic resonance imaging (MRI), which allows a deeper look of the joint and topographically describe the type of injury in the meniscus. However, there are situations in which the meniscus appears intact in the MRI and broken in the arthroscopy. Prospective, longitudinal, descriptive study, with data from records of patients that were intervened in a period from March 2013 to February 2018, at a third-level private sector hospital in Mexico City. Subjects over 18 years of age, of any gender, diagnosed with meniscus injury, unilateral or bilateral, who were operated arthroscopically where included. The diagnosis was made using magnetic resonance imaging and compared with arthroscopy. MRI in medial meniscus injuries has low specificity (47.6%) and sensitivity (58.8%) compared to various studies worldwide; the authors believe this could be because of the interpretation. In contrast, in lateral meniscus injuries, it has low sensitivity (10.35%) and high specificity (92%). The NPV found was 89.7% for lateral meniscus and 47.8% for medial.
