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.
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.
Clinical, magnetic resonance imaging, arthroscopic, and histological features have been carefully described to better characterize the AMMFL.
前内侧半月板股骨韧带（AMMFL）是一种非常罕见的结构，通常未被识别且报道较少。尽管尚未证实它是前膝痛的病因，但由于该结构的异常运动与内侧半月板损伤之间的关系，人们对此表示担忧。关于组织学检查，一些研究显示为半月板样纤维软骨，而另一些研究则将其鉴定为韧带样胶原纤维结缔组织。
我们报告了一名34岁芭蕾舞演员的病例，其双侧膝关节的AMMFL与内侧半月板撕裂相关。手术治疗半月板损伤，并在每个AMMFL的不同位置取两份活检样本以确定组织病理学组成。组织学检查显示为与半月板相符的纤维软骨组织。术后一年的随访评估表明症状完全缓解，患者已恢复体育活动。
已详细描述了AMMFL的临床、磁共振成像、关节镜和组织学特征，以更好地对其进行特征描述。
