Valgus and varus stress test results aren’t as direct as some other tests you might have had before. Instead of giving an exact range or a specific number, they give your provider a better understanding of what might be injured in your joint (and how severe the injury is).
The relationship of the forefoot to rearfoot is measured to quantify forefoot varus or forefoot valgus. To measure the relationship, the patient is prone lying with figure ‘4’ position for the non-examined lower extremity.
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] .
RESULTS. The means and SDs calculated at each of the 5 positions of tibiofemoral joint flexion tested are given in Table 2. Overall results indicated differences in slope values as the degrees of flexion changed (F 4,44 = 17.6, P < .001). A partial η 2 value of 0.62 indicates a moderate effect size.
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.
1 sty 2018 · The varus test involves applying forces to the knee in the opposite direction. Widening of the joint on the lateral side is indicative of lateral ligament and / or posterior cruciate ligament deficiencies. Variations of these tests involve placing the knee in varying amounts of flexion and rotation.
- Varus Stress Test: - Primary vs Secondary Restraints: - seationing of MCL results in marked valgus instability; - isolated sectioning of ACL, PCL, LCL, or posterolateral structures does not cause large increases in valgus angulation; - cutting of MCL + PCL results in more instability than any other combination;
