Posterior cruciate ligament. The posterior cruciate ligament (PCL) is one of four ligaments that hold the knee in place and provide added stability. More specifically, the PCL helps to ensure proper alignment of the femur and tibia, also called the thighbone and shinbone.Ligaments are fibrous tissue that usually connect bones.ccording to Medline Plus, the PCL is the strongest ligament in the knee. An injury to the posterior cruciate ligament may or may not require surgery, depending upon the severity of the injury, age of the patient, and whether other ligaments and cartilage are involved.
