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. For instance, an injury causing valgus stress often results from a blow to the lateral aspect of the knee, stressing the medial structures.
Clinical Significance of Pain Maneuver in Varus Valgus Knee Assessment
Patient Positioning and Examination Technique Proper execution of the varus valgus test knee relies heavily on correct patient positioning and examiner technique. It serves as a crucial adjunct to history-taking and standard radiographs, particularly when a complete tear or gradual attenuation of the ligament is suspected.
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. To test the medial collateral ligament, a valgus force is applied by pushing the tibia outward while stabilizing the thigh.

A positive test is indicated by increased gapping or a lack of a firm endpoint compared to the normal knee. Injuries are typically graded on a scale of one to three.
