Post./Ant. Instability

  1. Lachman's Test
  2. Anterior Drawer Test
  3. Pivot Shift Test
  4. Tibial Drop Back Test
  5. Quads Active Test
  6. Posterior Drawer Test
With slight distal traction on the leg, a valgus and internal rotation force is applied to the extended knee
With maintenance of the forces noted above, the knee is then flexed past 30.
Pivot shift test in an ACL deficient knee. 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.
