By applying a specific valgus or varus stress to the tibia while the knee is positioned at both 0 and 30 degrees of flexion, practitioners can quantify the degree of gapping or opening on the opposite side of the joint, thereby identifying subtle injuries that may not be apparent on standard imaging. It is critical to note that pain during the maneuver, even in the absence of increased laxity, is a significant clinical finding that warrants appropriate management.

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. For instance, an injury causing valgus stress often results from a blow to the lateral aspect of the knee, stressing the medial structures.
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. Understanding Varus and Valgus Deformities Before delving into the specific test maneuvers, it is essential to define the terms varus and valgus as they relate to the knee.

Patient Positioning and Examination Technique Proper execution of the varus valgus test knee relies heavily on correct patient positioning and examiner technique. 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.
