Dec 7, 2024 · Identifying a double posterior cruciate ligament sign is highly specific (98-100%) but of variable sensitivity (27-53%) for the detection of displaced bucket-handle tears 1. Associated signs include: flipped meniscus sign. fragment-in-notch …

Double PCL sign - appears on sagittal MRI images of the knee when a bucket-handle tear of a meniscus (most commonly the medial meniscus) flips into the intercondylar recess and comes to lie anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller PCL.

Jun 8, 2023 · A double posterior cruciate ligament sign from a torn medial meniscus can essentially only be seen in patients who have an intact anterior cruciate ligament (ACL) as this is required to prevent the flipped fragment from migrating further laterally, or not aligning parallel to the posterior cruciate ligament 1.

Feb 10, 2025 · double PCL sign (bucket-handle tears of the medial meniscus) - on sagittal view. double ACL sign (bucket-hand tears of the lateral meniscus) - on sagittal view. double anterior horn / flipped meniscus - on sagittal view. double delta sign- on sagittal view. disproportionately small posterior horn - on sagittal view

Double PCL sign is a highly specific indicator of displaced bucket handle meniscal tear. Double PCL sign from a torn medial meniscus can essentially only be seen in patients who have intact ACL. Lateral meniscus bucket handle tear, in the presence of torn ACL give double PCL sign too.

The body of the medial meniscus is discontinuous and diminutive posteriorly with excess meniscal tissue at the intercondylar fossa parallel to the sagittal plane simulating the double PCL sign, consistent with a bucket handle tear.

This case shows an incidental double-bundle posterior cruciate ligament (PCL). A double-bundle PCL consists of two separate bundles that originate adjacent to each other on the medial femoral condyle and insert on the posterior tibial plateau 1.

There is resultant 'ghost meniscus sign' posteriorly with only a tiny remnant of peripheral meniscus and the meniscopopliteal fascicles evident. A double delta sign is seen anteriorly on the sagittal images while a double PCL sign is evident in the intercondylar region.
