Signs and symptoms of a posterior cruciate ligament injury may include:

  • Pain. Mild to moderate pain in the knee can cause a slight limp or difficulty walking.
  • Swelling. Knee swelling occurs rapidly, within hours of the injury.
  • Instability. Your knee may feel loose, as if it's going to give way.

Signs and symptoms can be so mild that you might not even notice anything wrong. Over time, the pain may worsen and your knee may feel more unstable. If other parts of the knee have also been injured, your signs and symptoms will likely be more severe.
