Pivot Shift Test - Intraoperative

Video Description

The Pivot Shift Test is used to diagnosis ACL deficiency.

With slight distal traction on the leg, a valgus and internal rotation force is applied to the extended knee. With maintenance of this force, the knee is then flexed past 30°. In the intitial stages of knee flexion, the tibia will be anterolaterally subluxed on the distal femur with application of a valgus and internal rotation force at the knee. With further flexion of the knee (past approximately 30° ), the iliotibial band goes from an extendor to a flexor of the knee and the tibial anterolateral subluxation reduces (shifts) back into place.
