Pivot shift test—there are many variations of this test. The patient’s foot is wedged between the examiner’s body and elbow. The examiner places one hand flat under the tibia pushing it forward with the knee in extension. The other hand is placed against the patient’s thigh pushing it the other way. The lower limb is taken into slight abduction by the examiner’s elbow with the examiner’s body acting as a fulcrum to produce the valgus. The examiner maintains the anterior tibial translation and the valgus and initiates flexion of the patient’s knee. At about 20°–30° the pivot shift will occur as the lateral tibial plateau reduces. This test demonstrates damage to the posterolateral corner of the knee joint and the anterior cruciate ligament.
