Meniscal flounce

Meniscal flounces refer to the "ruffled" appearance of the inner margin of knee menisci. They were initially thought to be only an arthroscopic finding, as a result of joint distension and anesthetic muscle relaxants but are rarely seen on MRI. 

Meniscal flounces are rare, seen in around 0.2% of MRI scans, more frequently of the medial meniscus.

They are not associated with an increased incidence of meniscal tears, but can be mistaken for one. They reflect a degree of redundancy in the medial meniscus and are typically seen in the flexed knee. 

In coronal projections, they may make the inner margin of the meniscus appear truncated or blurred.

Out of interest, a flounce is a ruffle placed around a garment (often undergarment) as a decoration.
