Anatomic posterolateral corner repair and reconstruction

The posterolateral corner (PLC) ligament complex injury is a sprain (tear) of one of the four major ligament groups of the knee. The PLC is a group of ligaments on the lateral (outside) knee that helps maintain the normal relationship of the femur (thigh bone) and the tibia (leg bone) at the knee. It prevents the knee from buckling out and rotating excessively. This ligament is the least-injured major knee ligament. PLC sprains usually occur in association with other knee ligament injuries. When torn, this ligament does not heal well and often requires surgical repair or reconstruction, especially when torn in combination with other knee ligaments.
