Knee valgus is as valgus collapse and medial knee displacement. It is characterized by hip adduction and hip internal rotation, usually when in a hips-flexed position (the knee actually abducts and externally rotates)
→ One of the most commonly held theories is that reduced gluteal activity levels allow for a greater degree of hip internal rotation and consequently also tibial rotation and therefore knee valgus.
→ It is most commonly implicated in injuries involving the anterior cruciate ligament (ACL) but it also features as a risk factor in respect of other leg injuries, including patellofemoral pain syndrome, knee osteoarthritis, medial collateral ligament sprains and more general knee cartilage and meniscus damage.
→ The degree of genu valgum can be estimated by the Q angle, which is the angle formed by a line drawn from the anterior superior iliac spine through the center of the patella and a line drawn from the center of the patella to the center of the tibial tubercle.
→ 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.
→ A typical Q angle is 12 degrees for men and 17 degrees for women.
→ It is normal for children to have knock knees between the ages of two and five years of age, and almost all of them resolve as the child grows older.
→ 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.
PHYSICAL THERAPY –
→ Activating and developing the arches of the feet,
→ Waking up the outer leg muscles (abductors), and
→ Learning how to move the inner ankle bone inwards towards the outer ankle bone, and upwards towards the knee.
→ Strengthening exercise –
These all are Strengthning Execise.
