Knock knee is when at a standing position, the gap between the knees is narrower than the space between the feet, and often face each other. These symptoms are common in children but may also be found in adults. Knock knee appearing in children aged 4 - 5 years is normal as it is a part of normal development. There is no need to worry as it is naturally fixed within 2-3 years. However, if knock knee remains in children aged 8-9 or older, appropriate observation and treatment are required. Not only is treatment required for beauty purposes, but if left untreated, it may also become the cause of other problems such as bunions, arthritis, and plantar fasciitis. Knock knee causes the body weight to be concentrated on the inner foot, making the arch of the foot collapse. This leads to the continuous addition of stress and strain on the foot and leg joints as well as the muscles and ligaments. This makes running and walking more tiring, and painful, and increases the risk of injury. In the case of children or adults with minor knock knees, conservative treatment is given such as orthotic therapy and physical therapy to improve stability. Custom-made foot orthotics can improve walking posture and joint pain, or similar issues caused by knock knees.
