Interpretation. Positive findings may include excessive gapping at the medial joint and/or pain, indicating MCL damage. This may also indicate capsular or cruciate ligament laxity, depending on what degree of knee flexion the test is performed at. It should be noted that some joint gapping is considered normal at 30 degrees.

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.
Statistical significance, defined as a P value < 0.05 was determined using Student’s t test, and descriptive measures including mean, median, standard deviation and confidence intervals were ascertained. Results. There were 382 knees in 313 patients (mean age 65.7) in the varus group and 92 knees in 85 patients (mean age 67.1) in the valgus ...
In the current study, valgus forces compressed the mean lateral joint space width by 1.5 mm (95% CI, 1.1-1.8 mm) to a mean lateral joint space width of 5.1 mm (95% CI, 4.8-5.5 mm). The mean medial joint space width increased by 4.4 mm (95% CI, 4.0-4.8 mm) to 6.0 mm (95% CI, 5.7-6.3 mm).
Our results indicate that greater varus–valgus excursion is correlated to greater laxity, which may result in cartilage degeneration; however, patients with severe OA and greater laxity exhibited improved clinical performance.
When would I need a valgus or varus stress test? Your provider might perform a valgus or varus stress test if you have pain in your knee or elbow — or if you injured your leg or arm. These tests help them check for damage to the collateral ligaments that support your joints.
