Symptoms of a PLC Injury
Located on the outside of the knee joint, the posterolateral corner (PLC) of the knee acts to stabilize the knee against direct lateral or external forces. Injuries that occur to this area are often due to a sports impact injury, most often occurring in football, soccer skiing and basketball. Some symptoms of a PLC injury include:
- Side-to-side instability
- Difficulty twisting, turning and pivoting
- Slight swelling and pain along the outside of the knee
- A foot drop with a concurrent peroneal nerve injury
Patients may not notice the onset of instability patterns until several weeks to months after the initial injury. It is imperative to check this area for injury during an ACL/PCL repair for the best possible surgical outcome. One of the most common reasons for failed ACL reconstructions is an unrecognized PLC injury.
