Pivot Shift Test
- Pivot Shift Test is used to Diagnosis of rotatory instability related to ACL tear
- Flexing the knee from 0° (full extension) to 90° of knee flexion while applying an internal rotation stress to the tibia and a valgus stress to the knee.
- A positive test is seen with a rapid anterior subluxation of the tibia at 20–30° of flexion as it reduces under the femoral condyles.
- Functionally, this is reproducing the event that occurs when the knee gives way due to ACL rupture.
- Sensitivity: 24 %
- Specificity: 98 %
