Posterolateral Corner Repair
The posterolateral corner (PLC) of the knee includes 2 ligaments, the popliteal tendon and the knee capsule. These structures stabilize the knee against posterior or lateral forces. Injury to the PLC structures can occur during high-energy accidents. The anterior and posterior cruciate ligaments are commonly injured along with these structures. Mild injuries to the PLC may be repaired without reconstruction but reconstruction usually has much better results.
