Posterior Cruciate Ligament Injury (PCL)
PCL injury is caused by excess force on the knee. This may be from:
- A direct blow to the knee
- Twisting the knee
- Falling on a bent knee
An injury to the PCL may cause:
- Pain and swelling in the knee
- Soreness in the area behind the knee
- Weakness or instability in the knee
- Problems walking
- Pain when moving the knee
The PCL does not heal on its own. The goal is to ease pain and improve movement. This may be done with:
- Ice and rest to ease pain and swelling
- Medicine to ease pain and swelling
- Exercises to stretch and strengthen the muscles around the knee
- A brace to keep the knee from moving
- Crutches to take weight off of the leg
Some people may need surgery. It will remake the PCL with tissue from other areas of the body or from donor tissue.
