The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For example, in a valgus deformity of the knee, the distal part of the leg below the knee is deviated outward, in relation to the femur, resulting in a knock-kneed appearance.
Most commonly, varus and valgus stress to the knee is added. These variations constitute different tests with different statistical performance and should not be confused with the original. According to some sources, the sensitivity of the McMurray test for medial meniscus tears is 53% and the specificity is 59%.
The valgus stress test or medial stress test is a test for damage to the medial collateral ligament of the knee. It involves placing the leg into extension, with one hand placed as a pivot on the knee. With the other hand placed upon the foot applying an abducting force, an attempt is then made to force the leg at the knee into valgus. If the ...

Testing of the knee joint should be done using the following techniques and the findings compared to the contralateral, normal knee: [4] [5] Valgus stress at 0° and 20°- This test puts direct stress on the medial knee structures, reproducing the mechanism of injury. Valgus stress testing is done with the patient supine on the exam
The most common knee problems are: soft tissue inflammation, injury, or osteoarthritis. The mechanism of the knee injury can give a clue of the possible structures that can be injured. For example, applying valgus stress on the knee can cause medial collateral ligament rupture, meanwhile a varus force can cause lateral collateral ligament rupture
