Case contributed by Mohammad A. ElBeialy
Diagnosis almost certain

Presentation

Twisting knee injury

Patient Data

Age: 20 years
Gender: Male

Bucket-handle tear of the posterior horn medial meniscus (PHMM) with a '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 it lies anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller PCL.
