The pivot shift is a dynamic test of knee stability, passively carried out by the examiner. The movement is a combination of axial load and valgus force, applied by the examiner, during knee flexion from an …

The pivot shift test reproduces the instability felt by patients with a ruptured anterior cruciate ligament (ACL).

This test is considered positive if the proximal tibia subluxes anteriorly on the distal femur at about 30 degrees of flexion. In a positive test, the proximal tibia will clunk back into place while returning the …

If the tibia's position on the femur reduces as the knee is flexed in the range of 30 to 40 degrees or if there is an anterior subluxation felt during extension the test is positive for instability.

Feb 7, 2025 · The pivot shift test is positive in internal and neutral rotation; however, it is negative in external rotation. There is visible and palpable translation on the lateral aspect of the joint.

May 3, 2025 · A positive Pivot Shift Test is when the tibia subluxes anteriorly in extension and then "reduces" or slips back into place with a palpable jerk as the knee is flexed.

Sep 19, 2023 · What is the Positive pivot shift test? Flexion and valgus forces are then applied to the knee, and when the knee flexes, the iliotibial band moves from the extensor to the knee flexor and …

How to Interpret Pivot Shift Test Positive Finding: This test is considered positive for instability of the ACL if the tibia is subluxed anteriorly at the starting position when the knee is extended but reduces …

Mar 14, 2025 · The pivot shift test was originally conceived to identify anterior cruciate ligament laxity. But there is also a strong correlation between the more severe gradings on the pivot shift test and …
