Meniscoid lesions and fibrous bands are unique lesions, most likely of differing origin. Although they are similar in clinical presentation, their appearance at arthroscopy is clearly different. The meniscoid lesion is attached only at its origin at the inferolateral gutter on the anterior talofibular ligament. Fibrous bands are attached at two ends and may be found anywhere in the joint but are most common extending dramatically over the anterior joint line. Unexpected encountering of a fibrous band should alert the surgeon to carefully inspect the joint for other associated (occult) pathology. Because of the frequent association of bands with antecedent fracture, the observation of this lesion should lead the clinician to consider antecedent intra-articular fracture (transchondral fracture, malleolar fracture, and tibial pilon fracture) as a likely co-pathology. Careful examination of the ankle and review of the radiographs and other available images may be helpful in assessing the joint for these injuries when fibrous bands are encountered. The association of meniscoid lesion with prior soft tissue injury (sprain) is also important to understanding this lesion. Excision of both these abnormal lesions in concert with repair of coexistent pathology is associated with improvement of symptoms. Finally, both fibrous bands and meniscoid lesions are associated with symptoms that warrant closer inspection and observation. Whether the operative intervention is open or closed, the reader can benefit from the information presented.
盘状病变和纤维束是独特的病变，很可能起源不同。尽管它们在临床表现上相似，但在关节镜检查时的外观明显不同。盘状病变仅在其起源处附着于距腓前韧带下外侧沟。纤维束两端附着，可在关节内任何部位发现，但最常见于显著延伸至关节前间隙。意外遇到纤维束应提醒外科医生仔细检查关节以寻找其他相关（隐匿性）病变。由于纤维束常与先前骨折相关，观察到这种病变应使临床医生考虑先前的关节内骨折（经软骨骨折、踝关节骨折和胫骨平台骨折）作为可能的合并病变。当遇到纤维束时，仔细检查踝关节并回顾X线片和其他可用影像可能有助于评估关节是否存在这些损伤。盘状病变与先前软组织损伤（扭伤）的关联对于理解这种病变也很重要。同时切除这两种异常病变并修复并存的病变与症状改善相关。最后，纤维束和盘状病变都与需要密切检查和观察的症状相关。无论手术干预是开放还是闭合的，读者都能从所提供的信息中受益。
