PCL Tears

PCL tears are less common than ACL tears are.

They classically occur in the flexed knee, subject to forces from anterior against the proximal tibia. Often the site of tear is in the intermediate portion of the ligament, and there is concomitant damage to the posterior joint capsule.

In hyperextension injury, frequently there is a bony avulsion of the PCL from its tibial insertion site. Most often, lesions to the PCL are associated with lesions to the posterolateral corner of the knee.

Usually PCL tears can be diagnosed with a high degree of confidence on MRI. Contusional bmep is located in the anterior portions of the tibial plateau and in the overlaying anterior portions of the femoral condyles.
