Causes of PCL Injuries
PCL injuries are often due to a blow to the knee while it’s bent. Common causes include:
- Striking the knee against the dashboard during an auto accident
- Falling on the knee while it’s bent
Sports are a common cause of PCL injury. These injuries are especially common in:
- Football
- Soccer
- Baseball
- Skiing
An injury to the PCL can cause mild to severe damage. Doctors classify PCL injuries in these groups:
- Grade I: The PCL has a partial tear.
- Grade II: The ligament is partially torn and is looser than in Grade I.
- Grade III: The ligament is completely torn and the knee becomes unstable.
- Grade IV: The PCL is damaged along with another ligament in the knee.
PCL problems can be acute or chronic. Acute PCL problems are due to a sudden injury. Chronic PCL problems involve an injury that develops over time.
