What is PCL Injury?

Posterior cruciate ligament (PCL) injury happens far less often than does injury to the knee's more vulnerable counterpart, the anterior cruciate ligament (ACL). The posterior cruciate ligament and ACL connect your thighbone (femur) to your shinbone (tibia). If either ligament is torn, it might cause pain, swelling and a feeling of instability.

More About PCL Injury

Ligaments are strong bands of tissue that attach one bone to another. The cruciate (KROO-she-ate) ligaments connect the thighbone (femur) to the shinbone (tibia). The anterior and posterior cruciate ligaments form an “X” in the centre of the knee.

Although a posterior cruciate ligament injury generally causes less pain, disability, and knee instability than does an ACL tear, it can still sideline you for several weeks or months.
