The posterolateral corner (PLC) of the knee is a collection of ligaments and tendons over the outer-back part of the knee.

Injuries to the PLC often include tears to the lateral collateral ligament and the posterior cruciate ligament.

What Are The Symptoms Of A Posterolateral Corner (PLC) & Lateral Collateral Ligament?

At the time of injury, one will experience pain and swelling. Damage to multiple ligaments in the knee can give rise to the feeling of instability of the knee.

What Are The Treatment Options Available For A Posterolateral Corner (PLC) & Lateral Collateral Ligament?

As with most mild ligament injuries, bracing and physiotherapy may suffice to improve symptoms and function in the knee.

However, with persistent symptoms of instability, surgery in the form of ligament reconstructions will be necessary to stabilise the knee. In cases with multiple ligament injuries, early surgery is beneficial to restore knee stability and function.
