The varus stress test at 20-30° of knee flexion is the actual workhorse test to perform when one is assessing for posterolateral instability of the knee. This test isolates out the function of the fibular collateral ligament. In effect, there should be no increase in varus gapping of the knee at 20-30° of flexion when the fibular collateral The therapist applies a varus stress at the knee while the ankle is stabilized. The test is first done with the knee in full extension and then with the knee in 20-30 degrees of flexion. 1 Sensitivity The terms valgus and varus refer to angulation (or bowing) within the shaft of a bone or at a joint. It is determined by the distal part being more medial or lateral than it should be. Whenever the distal part is more lateral, it is called valgus. Whenever the distal part is more medial, it is called varus. Varus stress test elbow. Elbow examination stress tests. Valgus and varus stress test. The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or with the leg held between the examiners arm and trunk. A valgus stress test may be done to test the health of ligaments in the Elbow Valgus and Varus Stress Tests Elbow Varus Stress Test. Use: Test for varus lateral collateral ligament (LCL) instability at the elbow. Procedure: Elbow flexed, slight supination, support forearm, gapping in/out to assess ligament. Findings: Positive finding is pain, decreased mobility, laxity as compared with the unaffected side. Elbow Valgus Instability Stress Test Importance of Test: The lateral collateral ligament is important for resisting varus force at the knee due to its attachments along the femur and fibular head. With the fibular nerve also located around the fibular head, any injury with a mechanism of a varus force to the knee could potentially stress the fibular nerve as well. Varus Stress Test of the Knee: Genu Varum (aka bow-leggedness, bandiness, bandy-leg, and tibia vara), is a physical deformity marked by (outward) bowing of the lower leg in relation to the thigh, giving the appearance of an archer’s bow. Varus Stress Test may give False Positive result. Femur rolls externally if not supported; Slight knee flexion may allow for laxity; Stabilize ipsilateral ankle to isolate knee. Sit on edge of table; Patient's ankle rests on examiner's upper knee Purpose: The Varus Stress Test is used to assess the integrity of the LCL or lateral collateral ligament of the knee.This is a key test to perform when assessing for posterolateral instability of the knee. How to Perform Varus Stress Test. Position of Patient: The patient should be relaxed in the supine position. Performance: The examiner will support the knee and lower leg at the ankle A valgus test gauges lateral ligament damage on the inside of the joint, which could lead to an extended look at the elbows or knees. By contrast, the varus test determines if damage has been sustained to the other side of those joints, creating a bow-legged stance. This would be indicated by strain or deformity when stress is placed in the opposite direction as in the valgus test.
