Posterolateral instability is a condition which occurs when there is damage to the posterolateral corner, the structures that support the outside of the knee joint. It usually results from an injury to the knee ligaments. Dr. Steven Struhl at Shoulders & Knees offers posterolateral instability of the knee treatment to relieve pain and restore knee function at our clinics in NYC and Westchester.
Causes and Symptoms of Posterolateral Knee Instability
The posterolateral corner, or posterolateral ligamentous complex (PLC), includes multiple different structures that support the outside of the knee and provide stability. These include various ligaments and tendons that support the knee and allow quick shifts in movement and direction. Posterolateral instability of the knee can impact athletes that need to make pivoting or cutting movements. PLC injuries can be caused by:
- Direct impact or blow to the side of the knee
- Hyperextension injuries to the knee
- Knee dislocations (especially multiple occurrences)
- External rotation or twisting injury
An injury to the various ligaments and structures in the posterolateral corner can require treatment to restore function. The level of damage can determine the type of treatment required. Minimal damage to the PLC structures may be treated with supportive devices and immobilization of the knee, followed by physical therapy and rehabilitation. For ligament tears and more severe PLC structural damage, surgical treatment may be required.
