Title: Posterolateral knee injuries<br/>Author: Brian Corwell<br/><a href='http://umem.org/profiles/faculty/294/'>[Click to email author]</a><hr/><p>
        PCL injuries can sometimes have involvement of the posterolateral corner (PLC)</p>
<p>
        The dial test can be used to diagnose posterior lateral instability and help differentiate it from isolated PCL injuries</p>
<p>
        The dial test involves comparing the amount of external rotation of the lower leg at the knee while the knees are in 30° and in 90° of knee flexion.</p>

<p>
        An isolated injury to the posterolateral corner will result in more than 10° of external rotation in the injured knee that is present at 30° but not at 90° of knee flexion.</p>
