Knee Valgus and Varus Stress Tests
Varus and valgus stress tests of the knee are used to determine the presence of MCL or LCL pathology. To perform this test, have the patient lying supine with the hip flexed to 45 degrees, then take the patient’s leg and secure it between your body and elbow. Apply varus and valgus stress at the joint and assess for the degree of laxity at the knee joint.
