Question
What are the general causes of X-leg deformity?
Answer
X-leg deformity occurs when the knees touch each other when the feet are placed together, but the heels cannot touch. When walking, there is a step pattern where the knees collide again. After the feet are extended forward, only the knees can touch, and there is a noticeable gap between the thighs and calves. During growth, deformities of the lower limbs are the main cause of X-leg deformity. A small portion is caused by developmental disorders of cartilage, injuries, fractures, etc. Treatment for X-leg deformity includes surgery on the legs, use of braces, bandages, physical training, and wearing orthotic insoles. Children with rickets must undergo regular and irregular rickets treatment. At the same time, parents should be cautious not to let children learn to walk too early to avoid X-leg deformity. As children grow older, X-leg deformity may lead to knee pain and affect joint movement, which will easily lead to osteoarthritis of the knee.
