Radiographic Evaluation for Valgus Knee Deformity

Assessment Methods

Radiographic evaluation using weight-bearing AP and lateral radiographs is essential for assessing valgus knee deformity, as recommended by the American College of Radiology 1
Standing long-leg (hip-to-ankle) views provide optimal assessment of alignment in patients with valgus knee deformity, according to the American College of Radiology 1, 2
AP views obtained in 10 degrees of internal rotation improve interpretation of varus and valgus alignment compared to neutral AP views, as suggested by the American College of Radiology 1, 3

Mechanical axis deviation Zone 2 or greater despite optimized medical treatment may require surgical intervention, as indicated by research published in Nature Reviews 4
Guided growth techniques depend on remaining growth potential and must be carried out at least 2-3 years before skeletal maturity, according to guidelines from Nature Reviews 5
