Medial meniscal cysts. Case report and review of the literature.

Cysts of the medial meniscus are rare. They may present as a local tumor or may mimic signs of an internal derangement. The pathology may be treated by arthroscopic subtotal meniscectomy alone if the meniscal tear and cyst communicate, by local cyst excision and reattachment of the meniscus, or total meniscectomy. Two cases are presented with a review of the literature.
