The Posterior Cruciate Ligament (PCL) is one of the ligaments found on the back of the knee that connects the bones of the knee. This tough band of tissue attaches the femur (thigh bone) and tibia (shin bone) at the knee joint. The PCL is a major knee stabilizer that prevents extreme rotation, and maintains normal lower extremity alignment. Without the PCL, the tibia would move too far backward relative to the femur. The term Posterior Cruciate Ligament may sound familiar: this is because the PCL is similar to the Anterior Cruciate Ligament (ACL), which also prevents the tibia from moving out of place. However, the ACL which prevents excessive anterior movement of the tibia relative to the femur, is injured more often than the PCL.
PCL injuries typically occur from a strong force that is applied to the knee. PCL injuries occurs in association with car crashes (dashboard injury), pivoting athletic movements, or landing hard on the anterior knee. Dr. Riley J. Williams, orthopedic knee surgeon treating patients in Manhattan, New York City and the surrounding New York boroughs, has extensive experience diagnosing and treating PCL injuries.
