posteromedial bundle of posterior cruciate ligament ( RID2786 )
The referrer suspected partial PCL tear. In this case, I think there is full thickness or near full thickness tear of the vertical segment of the posteromedial bundle of the PCL (white arrows). The anterolateral bundle is sprained but not torn. Note the intact meniscofemoral ligaments of Humphrey and Wrisberg (red arrows). The attached article suggests that the intact MFLs may splint the PCL as it heals when treated conservatively. This was the isolated injury in this knee. [ Article ]
