The posterior cruciate ligament (PCL) is located in the back of the knee joint, behind the ACL and is one of the four ligaments responsible for maintaining stability in the knee joint. The PCL makes sure that the shin bone does not slide too far backward. PCL injuries are often undiagnosed, even though it is estimated that they make up to 20% of knee ligament injuries.
Injuries to the PCL most commonly occur when the shin is forcefully hit while the knee is bent. It is referred to as a “dashboard injury” because it can often be seen in car crashes where the person’s shins strike the dashboard of the car. This can also happen in sports when an athlete falls on the front of the knee.
Injury to the PCL is commonly associated with traumatic injuries involving damage to many different knee structures, including other ligament tears, meniscus tears, and cartilage damage.
Symptoms of PCL Tears
The symptoms of a PCL injury are very similar to the signs of an ACL tear: knee pain, swelling, and decreased range of motion. Patients may also experience a popping sensation when the injury occurs and have problems with knee stability in the weeks that follow.
