When would I need a valgus or varus stress test? Your provider might perform a valgus or varus stress test if you have pain in your knee or elbow — or if you injured your leg or arm. These tests help them check for damage to the collateral ligaments that support your joints.
The valgus stress test, also known as the medial stress test, is used to assess the integrity of the medial collateral ligament (MCL) of the knee. MCL injuries are common in the athletic population and can occur as either isolated injuries, or combined with other structural injuries [1].
The examiner checked the patient's range of motion and performed other disease-specific tests, such as the McMurray test, anterior/posterior drawer test, pivot shift test, and varus/valgus stress...
Valgus alignment is known as knock knee syndrome. It shifts the load-bearing axis to the outside of the knee joint, forcing the knees to be positioned inward. Varus alignment, or bow leg syndrome, causes the load-bearing axis of the leg to shift to the inside, pushing the knees outward.
The valgus and varus stress tests are specialized maneuvers used to assess the stability of the knee joint. The valgus stress test focuses on the MCL by applying an outward force to the knee, while the varus stress test targets the LCL by applying an inward force.
The moving valgus stress test, described by O’Driscoll et al, 11 was found to be 100% sensitive and 75% specific for MCL injuries. The test is performed with the patient upright; the shoulder is placed in 90° of abduction and maximal external rotation with the elbow in maximal flexion.
Special tests. Adduction (varus) stress test. Purpose: The varus stress test shows a lateral joint line gap. Performance: A varus stress test is performed by stabilizing the femur and palpating the lateral joint line. The other hand provides a varus stress to the ankle.
