SymptomsBy Mayo Clinic staff
Signs and symptoms of a posterior cruciate ligament injury may include:
- Mild to moderate pain in the knee
- Rapid onset of knee swelling and tenderness (within three hours of the injury)
- Pain with kneeling or squatting
- A slight limp or difficulty walking
- Feeling of instability or looseness in the knee, or the knee gives way during activities
- Pain with running, slowing down, or walking up or down stairs or ramps
Signs and symptoms may be mild or vague, and 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 are affected, your signs and symptoms will likely be more severe.
