The patient should ideally be supine on the examination table with the knee fully extended for the initial assessment of ligamentous laxity. Injuries are typically graded on a scale of one to three.
Diagnosing Knee Ligament Tears with Varus Valgus Stress Testing
A varus deformity, often colloquially described as bow-legged, occurs when the distal aspect of the limb angles inward, causing the knees to point toward each other while the ankles remain apart. Interpreting the Results and Grading System Interpretation of the varus valgus test knee is based on comparing the affected limb to the contralateral side and assessing the quality of the end feel.
To test the lateral collateral ligament, a varus force is applied by pushing the tibia inward. To test the medial collateral ligament, a valgus force is applied by pushing the tibia outward while stabilizing the thigh.
Knee Ligament Tear Diagnosis Test: Assessing Varus Valgus Stability
This physical examination maneuver helps clinicians evaluate the lateral and medial compartments of the knee, which bear the majority of the body's weight during ambulation. Additionally, the test is indicated in patients reporting persistent medial or lateral knee pain, instability, or a sensation of the knee "giving way" during rotational activities.
