Double delta sign (meniscal tear)

Last revised by Dr Mohamed Saber on 24 Jan 2021

The double delta sign is a feature that has been described in a bucket handle meniscal tear when the inner meniscal fragment flipped anteriorly adjacent to the anterior horn of the donor site and is referred to as a displaced bucket handle tear. The original location of the posterior horn remains empty giving the appearance of a ghost meniscus.
