Posterolateral Corner Reconstruction
The posterolateral corner is a part of the knee joint located on the outer side and back of the knee. The structure includes lateral collateral ligament, the popliteus tendon, and the popliteo-fibular ligament. Posterolateral corner injury refers to the damage in the structure of the posterolateral corner. Posterolateral corner injury may be caused due to motor-vehicle accidents, athletic trauma and falling with hard surface hitting directly. Your doctor may suggest X-ray and MRI scan to determine the extent of injury. Posterolateral corner injury is divided into grade 1, 2 or 3 depending on the severity of injury. Treatment of posterolateral corner injury depends on the severity of the injury. Grade 1 and grade 2 injuries may be treated conservatively with non-surgical procedure (wearing knee brace for 8 to 12 weeks). Grade 3 injures require posterolateral corner reconstruction for treatment.
