2021年9月10日 · What is a posterior cruciate ligament injury? Your posterior cruciate ligament (PCL) runs along the back of your knee and connects your thighbone to the top of your lower leg bone. This ligament keeps your bones in place and helps your knee move smoothly. When the PCL is sprained or torn, it’s called a posterior cruciate ligament injury.

A PCL sprain happens when force is applied beyond what the PCL tensile strength is capable of resisting. The tensile strength of the PCL is well documented in the literature and ranges from 739 to 1627 N (3).

2023年9月13日 · WebMD explains the causes, symptoms, and treatment of an injury to the PCL - or posterior cruciate ligament - a knee ligament.

2023年5月31日 · PCL injuries are traumatic knee injuries that may lead to posterior knee instability and often present in combination with other ipsilateral ligamentous knee injuries (i.e PLC, ACL). Diagnosis can be suspected clinically with a traumatic knee effusion and increased laxity on a posterior drawer test but requires an MRI for confirmation.

An injury to the posterior cruciate ligament requires a powerful force. A common cause of injury is a bent knee hitting a dashboard in a car accident or a football player falling on a knee that is bent.

Injury to the posterior cruciate ligament (PCL) can range from a stretch to a total tear or rupture of the ligament. These injuries are relatively uncommon. [5] They occur less frequently than anterior cruciate ligament (ACL) injuries as the PCL is broader and stronger.

2024年10月17日 · A Posterior Cruciate Ligament (PCL) sprain is a significant knee injury that affects the ligament responsible for stabilizing the knee joint. The PCL is located in the back of the knee and works with the anterior cruciate ligament (ACL) to control the backward and forward motion of the knee.

PCL sprains are classified as Grade I (minimal damage), Grade II (moderate ligament damage and partial tearing), and Grade III (complete ligament tear). A PCL sprain or tear may result in moderate pain.

A PCL injury is a partial or complete tearing or stretching of any part of the posterior cruciate ligament. It usually occurs when the knee is overextended (hyperextension). Learn more about symptoms, diagnosis and treatment at Penn.

2024年3月19日 · A PCL sprain is the least common injury associated with sprained knee ligaments. The PCL is the strongest ligament in the knee which makes the likelihood of it being injured the lowest out of the 4 main ligaments.
