    Cause[ edit ] While genu valgum is often a symptom of genetic disorders it can be caused by poor nutrition. A major contributor to genu valgum is obesity, and far less commonly calcium and vitamin D deficiencies [1]. Excess of fluoride can lead to genu valgum, osteoporosis and osteosclerosis. In women, the Q angle should be less than 22 degrees with the knee in extension and less than 9 degrees with the knee in 90 degrees of flexion. In men, the Q angle should be less than 18 degrees with the knee in extension and less than 8 degrees with the knee in 90 degrees of flexion.

    These relationships can be used to characterize the source and severity of valgus malalignment, as advocated by Paley et al. C, Valgus deformity in the tibia is characterized by a medial proximal tibial angle MPTA greater than 90 degrees. D, Valgus deformity in the femur is characterized by a lateral distal femoral angle LDFA less than 85 degrees.

    If symptoms are prolonged and pronounced or hereditary, doctors often use orthotic shoes or leg braces at night to gently move a child's leg back into position. If the condition persists and worsens later in life, surgery may be required to relieve pain and complications resulting from severe or hereditary genu valgum.

    Available surgical procedures include adjustments to the lower femur and total knee replacement TKR.

    Weight loss and substitution of high-impact for low-impact exercise can help slow progression of the condition. With every step, the patient's weight places a distortion on the knee toward a knocked knee position, and the effect is increased with increased angle or increased weight.

    Even in the normal knee position, the femurs function at an angle because they connect to the hip girdle at points much further apart than they connect at the knees. Physiologic vari- ment.
