Leg Length Discrepancy
If your child has one leg that is longer than the other, he or she has a common problem known as leg length discrepancy.
The greater the discrepancy between the legs, the more problems it can cause. The child will compensate for uneven leg lengths by standing and walking abnormally, and may develop problems in his or her posture, spine, hip, knee and ankle.
The treatment depends on the difference between the legs, the underlying cause and the age of your child. It can occur in adults very rarely, with one cause being a complication of hip or knee surgery, in which LLD is a very small risk.
