You need to perform in 20-30o flexion and full extension. For the valgus stress test, lift the patient’s leg and hold under your arm. Put one hand on the lateral aspect of the knee joint and one on the medial aspect, then give the pressure from lateral side and watch for movement (opening) of medial side (medial collateral ligament). Alternatively, one hand holds the heel and one hand push the knee. A positive test is valgus movement of the leg with or without pain. For the varus stress test, force is from the opposite direction, i.e. push to medial side and feel the opening of lateral side (lateral collateral ligament). A positive test is varus movement of the leg with or without pain, depending on acute or chronic condition. Then test on full extension, positive test in full extension means associated cruciate ligament injury because all the ligaments of the knee are most taut in this position therefore movement is controlled. Finally, compare with the opposite limb. Valgus stress test. Note the position of hand. Varus stress test. Position of hands is opposite to valgus stress test.
