"The double PCL sign is associated with bucket-handle tears of the medial meniscus that occur in the presence of an intact anterior cruciate ligament (ACL). A bucket-handle tear is a longitudinal tear of a meniscus that results in a displaced but attached meniscal fragment. . The fragment may become displaced into the notch between the PCL and the medial tibial eminence in the midline, with the fragment orientated parallel to the PCL." Reference- November 2004 Radiology, 233, 503-504.
In our case of running injury this sign is well seen on the sagittal images and confirmed on coronal images.
