The posterior cruciate ligament (PCL) originates from the anterior edge of the intercondylar notch and a part of the medial condyle of the femur. It is directed posteriorly and laterally, attaching behind the intercondylar eminence near the posterior edge of the tibia. The function of this ligament is to prevent the backward displacement of the tibia. Injuries to the posterior cruciate ligament are less common than injuries to other ligaments that stabilize the knee. The most frequent cause of such injuries is a blow to the knee while it is in a flexed position or during hyperextension of the knee with sudden rotation. A blow to the knee from a car accident can also cause injury. These injuries are most common in contact sports. Possible injuries include sprains, partial tears, or complete ruptures. Treatment methods for posterior cruciate ligament injuries include conservative and surgical approaches, but diagnostic procedures must be performed beforehand. Milder ligament injuries mostly heal after a period of rest, following the RICE protocol. More severe injuries require surgery and a longer recovery period. After surgery, a rehabilitation process follows, which includes taking a medical history, clinical examination, subjective and objective assessment, specific tests and measurements to evaluate the condition, and the application of physical therapy procedures.
