There is usually little or no effect on the ability to walk for those with genu varum. Children usually have no symptoms, while adults may feel some discomfort on the outside of their knees. If left untreated, however, uneven stress and wear on the knees often leads to the early onset of arthritis. Visually, the legs of those with genu varum are bowed outward.
Causes and Risk Factors
The most common cause of genu varum is rickets or any condition that prevents bones from forming properly. Skeletal problems, infection and tumors can affect the growth of the leg, which can cause one leg to be bowed. Arthritis, if it affects the inside of the knee more than the outside can lead to bowed legs, as can a fracture that does not heal properly. Some professions, such as jockey, can lead to bow-leggedness, as can physical trauma.
