PCL Tears!
PCL is stronger than the ACL, prevents psoterior tibial translation and has two bands (anterolateral and posteromedial).
The meniscofemoral ligaments (Wrisberg and Humphrey) are part of the PCL “complex”.
Mid substance tears are usually associated to forced posterior translation of the tibia on a flexed knee (dashboard injury). With this mechanism of unjury, the pattern of bone contusion is at the anterior tibia and posterior femoral condyle, as seen in this case.
Knee hyperextension PCL tears are usually seen as avulsion from the tibial attachment and usually associated to other ligamentous injury. With this mechanism of injury, there is knee subluxation/dislocation and can have associated neural/vascular damage. Pattern of bone contusion is anterior tibia and anterior femoral condyle.
Up to 60% of PCL injuries associated to injury of the posterolateral corner.
Surgery not as popular as with ACL tear and usually performed with complex injuries and/or prominent posterior tibial translation.
