The Secret of Knees: Do you know what "knee varum" is? The reason behind it is surprising!
In daily life, many people do not know much about their physical condition. Among them, genu valgum (genu valgum), commonly known as "knee varum", is a common knee joint deformity. This condition causes the knees to angle inward and touch each other with the legs straight. For many people, it may appear briefly in childhood, but the condition may become more severe as they age, especially if it is caused by certain medical conditions.
The cause of genu varum may involve a variety of factors, such as genetics, malnutrition, or trauma. Understanding the science behind it is crucial to treatment.
Causes of genu varum
The occurrence of knee varum is related to many factors, including nutrition, genes, trauma, unexplained or physiological factors and infection. Among them, nutritional rickets is considered to be one of the important causes of genu varum in children.
Nutritional rickets
This condition is mainly caused by unhealthy lifestyle, such as vitamin D deficiency caused by lack of sunlight exposure, and insufficient calcium intake in the diet. In addition, some patients may develop vitamin D-resistant rickets or X-linked hypophosphatemia due to genetic abnormalities.
Skeletal dysplasia
Skeletal dysplasia is a hereditary skeletal disease involving systemic bone deformation, and genu varum is one of its common symptoms. Confirmation requires a comprehensive skeletal X-ray.
Diagnostic methods
Clinically, doctors will use the Q angle to evaluate the degree of knee varum. The Q angle is the angle formed by the line connecting the hip joint to the knee joint and the line connecting the knee joint to the tibial tubercle. Generally speaking, the Q angle should be below 22 degrees for women and below 18 degrees for men.
In adults, the normal hip-knee-ankle angle should be between 1.0° and 1.5°, while in children there is a different range.
Treatment methods
How genu varum is treated depends on its underlying cause. If it is developmental genu varum, it will usually repair naturally with growth; if it is caused by nutritional rickets, you need to improve your lifestyle, including increasing sunlight exposure and consuming calcium-containing foods.
Surgical treatment
If the knee varum condition remains severe despite conservative treatment, surgery may be required. A common surgical procedure is guided growth surgery to correct deformed bones.
Other treatment methods
Treatment for adult genu varum usually depends on the symptoms and the degree of damage to the knee joint, and may require fracture correction or joint replacement surgery. In addition, patients should also engage in aerobic exercise and lose weight to reduce pressure on the knee joint.
When treating genu varum, working with a physical medicine specialist can help patients achieve better results.
Conclusion
Knee varum is a complex joint deformation problem with equally diverse causes and treatments. Understanding this condition can not only promote personal health management, but also prevent possible long-term effects. So, have you ever thought about the health of your knees?
