What is posterior sag sign?
The Posterior Sag Sign indicates the presence of a posterior cruciate ligament tear. To look for this sign, the patient lies supine with their hips flexed to 45˚ and their knees flexed to 90˚. Normally, the medial tibial plateau lies at least 1 cm anterior to the femoral condyle when viewed directly from the side.
What does the posterior sag test test for?

What are the signs and symptoms of PCL tear?
Signs and symptoms of a PCL injury can 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.

How is posterior sag test done?
In supine subjects hip and knee are flexed to 90°while the examiner supports the leg under the lower calf or heel in the air. A positive sign is a posterior sag of the tibia caused by gravitational pull.
What is posterior sag knee?
A torn PCL allows the free tibia to slide posteriorly under the fixed femur, creating the posterior sag sign. A positive sag sign is characteristic of PCL injuries and results when gravity pulls the tibia downward greater than 10 mm.
How do you tell if PCL is torn or sprained?

What should I do for a posterior sag exam?
Support the leg under the lower calf or heel in the air. Patients leg should be relaxed. Observe the position of the tibia in comparison to the femur. Have the patient lie supine on the exam table. Place the patient’s involved limb in 45° of hip flexion and 90° flexion of the knee.
Why do I have a posterior sag in my knee?
In the position of 45 degrees of hip flexion and 90 degrees of knee flexion, gravity places a force on the tibia that pulls the tibia posteriorly, but is blocked by an intact PCL. In the absence of a PCL, the tibia appears to “sag.”
