Execution:
- Patient is in supine lying position with the hip in 45° and the knee in 90° of flexion
- The examiner then looks for a ‘sag’ of the tibia posteriorly in comparison with the tibia of the other leg
- Some authors describe that the posterior sag is more marked when the examiner holds onto the patient’s heel while the hip is flexed to 90° and gravity pulls on the leg
Positive Outcome: In a normal situation the tibia plateau sticks out 1 cm anteriorly in relation to the femoral condyles. With a torn PCL this step is lost, which is why this test is also called Step-Off Test
