  • Title: Intra-articular soft-tissue masses of the ankle. Meniscoid lesions and transarticular fibrous bands.
    Author: Stienstra JJ.
    Journal: Clin Podiatr Med Surg; 1994 Jul; 11(3):371-83. PubMed ID: 7954206.
    Abstract:
    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.
