The posterior cruciate is one of the two cruciate ligaments which are important in stabilising the knee.

The posterior cruciate ligament (red arrow) prevents the femur sliding too far forward in relation to the tibia. The anterior cruciate ligament (not shown) has an opposite function.


The torn posterior cruciate ligament

Injuries to the posterior cruciate ligament are less frequent than those of the anterior cruciate, because it requires a greater force to tear the ligament or pull it from the bone.

Symptoms of a tear include pain at the time of injury, which is not always severe, swelling of the knee which again is sometimes tense but not always so, and instability with a limp and feelings of 'giving way'.
