Genu valgum , commonly called " knock-knee ", is a condition in which the knee is angled and touch each other when the foot is straightened. Individuals with severe valgus deformity usually can not touch their legs simultaneously while straightening their legs. This term is derived from the Latin genu , "knee", and valgus which actually means bending outward, but in this case it is used to describe the distal part of the bent joint knee out and thus the proximal portion appears inward. For quotations and more information about using Valgus and Varus words, please visit the internal links to -varus.
Mild genu valgum is diagnosed when a person stands tall with his touching leg also shows knee touch. It can be seen in children from 2 to 5 years of age, and is often corrected naturally as children grow. However, this condition may continue or worsen with age, especially when it is the result of a disease, such as rickets or obesity. Idiopathic genu valgum is a form of either congenital or unknown cause.
Other systemic conditions may be associated, such as Schnyder crystalline dystrophy of the cornea, an autosomal dominant condition that is often reported with hyperlipidemia.

Penyebab
While genu valgum is often a symptom of genetic disorders, it can be caused by poor nutrition. The main contributors to genu valgum are obesity, and a much lower deficiency of calcium and vitamin D.

Diagnostic test
The degrees of the genus valgum can be estimated by Q angle , which is the angle formed by the line drawn from the anterior superior iliac spine through the center of the patella and the 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 degree flexion. In men, the Q angle should be less than 18 degrees with the knee in the extension and less than 8 degrees with the knee in 90 degree flexion. The typical Q angle is 12 degrees for men and 17 degrees for women.
Treatment
People with knee taps often have tears on the inside of their feet, and the ankle bone is generally lower than the outer ankle bone. Adults with uncorrected valgum genes are usually susceptible to injuries and chronic knee problems such as chondromalacia and osteoarthritis. This in turn can cause severe pain and problems in walking.
It is normal for children to have knees knock between the ages of two and five, and almost all recover as the child gets older. If symptoms are extended and spoken or hereditary, doctors often use orthotic shoes or leg buffers at night to gently move the child's legs back into position. If the condition continues and worsens in the future, surgery may be needed to relieve the pain and complications resulting from severe valgus genes or heredity. Available surgical procedures include adjustment of the lower thigh bone and total knee replacement (TKR).
Weight loss and high impact substitution for low-impact exercise can help slow the progression of the condition. With each step, the patient's weight placed a distortion in the knee toward the knee-stricken position, and the effect increased with increasing angle or weight gain. Even in the normal knee position, the femur works at an angle because they are connected to the hip girdle at much farther points apart from those connected to the knee.
Working with a physical medicine specialist such as a physiotherapist, or a physiotherapist can help patients learn how to improve outcomes and use leg muscles properly to support bone structure. Alternative or complementary treatments may include certain procedures of Iyengar Yoga or Feldenkrais Method.
Rarely, bone malformations underlying knee beat can be traced to a lack of necessary nutrients for bone growth, which can cause conditions such as rickets (lack of bone nutrition, especially vitamin D and calcium diets), or scurvy (vitamin C deficiency). Correction of underlying vitamin deficiencies can restore a more normal development of bone growth.
