    Video: How to perform a Pivot Shift Test

    Pivot Shift Test: Clinical test for ACL assessment

    The Pivot Shift Test is a clinical examination test destined to diagnose knee instabilityWatch the video below to see how it is performed.

    Video explanation:

    In this video, the Pivot Shift Test that is performed is negative. To perform the test, the patient must be placed in a supine position with the hip flexed to 30 degrees. The examiner should stand lateral to the patient of the knee that is being examined. The lower part of the leg and the ankle are then grasped while maintaining 20 degrees of internal tibial rotation. The other hand is to grasp the lateral portion of the leg at the level of the superior tibiofibular joint, increasing the force of internal rotation. 

    While maintaining the internal rotation, a valgus force is applied to the knee while slowly applying a flexion. At this point, if the tibia's position reduces while the flexion takes place between 30 40 degrees or if an anterior subluxation is felt during extension, the test is considered positive.

    In the continuity of what is indicated in the video, it relies on many subjective factors such as:

    • The clinician's experience
    • Muscle relaxation
    • Inherent knee variability

    The test is also considered uncomfortable and may only be performed once, as the patient is unlikely to relax enough for a second one. It is therefore recommended to apply other objective methods of ACL assessment such as using an arthrometer to confirm the diagnosis or follow the state of the ACL graft over time after surgery.

    Advantages of using arthrometers for treating knee ligament injuries

    Below are the main advantages of using arthrometers for treating injuries related to the ACL:

    • Objective results: Keep an organized ACL database on your patients
    • Pre/Post surgery use: Confirm correct diagnosis and guarantee knee stability after surgery
    • Precise assessment: Answer your patients' exact needs
    • Enhanced communication: Gain patient trust and optimize professional communication
    • Reproducible / None-invasive test: Test your patient correctly and rigorously  compare results
