The posterolateral corner (PLC) reconstruction is a surgical procedure that is done to treat injuries or instability of the posterolateral part of the knee joint. Posterolateral corner is a challenging region of the knee which helps in supporting the valgus force and prevents the external rotation of the tibia. Injuries to this area are usually associated with other ligament injuries of the knee, for instance, ACL tears.

PLC reconstruction usually entails repairing or reconstructing several structures such as the LCL, popliteus tendon, PFL, and possibly the lateral capsule. The purpose of the surgery is to achieve stability and functionality of the posterolateral aspect of the knee joint.

It can be done with autografts (tissue taken from the patient’s own body) or allografts (tissue from another person). Some of the most frequent choices for the graft include the hamstring tendons, the quadriceps tendon, or the iliotibial band.

The reconstruction of the PLC requires rehabilitation to ensure the best possible results. Physical therapy usually starts shortly after surgery to achieve the goal of improving the range of motion, strength, and function of the knee. The period of time for returning to sports or other physical activities depends on the recovery of the individual and the type of surgery performed.

As with any surgical procedure, there are risks and potential complications of PLC reconstruction such as infection, stiffness, nerve injury, and graft failure. It is crucial for the patients to address these risks with the surgeon and follow the recommended postoperative regime to enhance the possibilities of a favorable outcome.
