PLC Instability

  1. Ext. Rotation Recurvatum Test
  2. Varus Stress Test
  3. Posterolateral Drawer Test
  4. Reverse Pivot Shift Test
  5. Dial Test at 30
  6. Dial Test at 90
  7. Varus Thrust Gait

With a slight downward pressure to the femur, the great toe is lifted and the amount of recurvatum (hyperextension) of the knee is assessed.

The amount of hyperextension of the injured knee must be compared to the normal contralateral knee.
This is the initial starting point for the external rotation recurvatum test.
A significant amount of increased recurvatum and varus motion is seen with a combined PCL and PLC injury in this patient.
