Medial Meniscal Flounce

A meniscal flounce is considered a normal variant characterized by a wavy or folded appearance of the inner edge of the medial meniscus. It looks like a carpet that has a wrinkled edge.

Because meniscal tears may result in a flouncelike fold, a meniscal flounce should not be called if there is any finding suggestive of a meniscal tear.
