What are the three main Stabilisers of the posterolateral corner of the knee?
The three major static stabilizers of the PLC are the fibular (lateral) collateral ligament (FCL), the popliteus tendon (PLT) and the popliteofibular ligament (PFL)(9).
What is posterolateral corner reconstruction?
Posterolateral corner reconstruction is the surgical repair of a significant injury to the posterolateral corner of the knee. PLC tears are most often sustained from an acute injury. For example, a blow to the inner or medial knee while playing football or during a motor vehicle accident can cause a tear of the PLC.
What is posterior knee?

What is lateral side of knee?

What is the lateral ulnar collateral ligament?
The lateral ulnar collateral ligament (LUCL) is an important stabilizing ligament of the elbow. It is involved in many functions of everyday life such as lifting and pushing one’s self out of a chair. This ligament is usually injured by way of a traumatic injury as opposed to overuse and wear.
What can cause posterior knee pain?
There is a large variety of potential causes of posterior knee pain. These include soft-tissue injuries, tendon injuries, vascular, and neurologic causes. Injuries to the soft-tissues and tendons are more common while neurologic and vascular injuries occur less frequently [18].
