Posterior cruciate ligament tears:
Tears of the posterior cruciate ligament (PCL) are less common than ACL injuries due to the greater strength of the PCL. Furthermore, it is commonly under diagnosed because many people can function normally without a PCL. However, this can lead to significant osteoarthritis later in life.
PCL injuries are often due to a blow to the shin while the knee it’s bent. Common causes include:
- Striking the knee against the dashboard during an motor vehicle accident
- Falling on the knee whilst bent
In sports a PCL injury can occur when the athlete falls to the ground on a bent knee
