Previously discussed here, meniscal flounce is a normal variant characterized by a single fold along the free edge of a meniscus. By definition it exists in the absence of a meniscal tear. While usually seen in the medial meniscus, the above images demonstrate the finding on the lateral meniscus.

Hi,
ReplyDeleteThanks for another nice case. I do not see these very often. Also, they are much more common in the medial meniscus, making this an even better case.

Hi,
ReplyDeleteVery nice blog site. Flounce is most often incidental and of no consequence. Rarely, similar finding can be seen if root of the meniscus is torn. So, its a good idea to look at the roots in detail when meniscal flounce is encountered.
