摘　　要：BACKGROUND The anteromedial meniscofemoral ligament(AMMFL)is a very rare entity,commonly unrecognized and underreported.Although it was not proved to be a cause of anterior knee pain,concerns have been raised on the relationship between the presence of this structure and medial meniscus injury secondary to its abnormal motion.Regarding histologic examination,some studies have shown meniscus-like fibrocartilage,while others have identified it as ligament-like collagenous fibrous connective tissue.CASE SUMMARY We report the case of a 34-year-old ballerina with an AMMFL associated with a torn medial meniscus of both knees.Surgery was performed to treat the meniscal injury and two biopsies of each AMMFL were taken in different locations to define the histopathological composition.Histologic examination revealed fibrocartilaginous tissue compatible with meniscus.Follow-up evaluation one year after surgery evidenced full remission of symptoms and the patient had resumed her athletic activities.CONCLUSION Clinical,magnetic resonance imaging,arthroscopic,and histological features have been carefully described to better characterize the AMMFL.
