Case contributed by Dr Mohammad A. ElBeialy

Presentation

Twisting knee injury

Patient Data

Age: 21 years
Gender: Male
MRI
  • Bucket-handle tear of the posterior horn medial meniscus (PHMM) with "double PCL" sign.
  • Full-thickness tear of the femoral attachment of the ACL.
  • Mild joint effusion.

Case Discussion

The double PCL sign appears on sagittal MRI images of the knee when a bucket-handle tear of a meniscus (medial meniscus in 80% of cases) flips medially so that comes to lie anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller PCL.
