The best age for correction of XO-type legs is, in practical terms, the earlier the better.
If early diagnosis is possible, children around three years old can be fixed with lower limb external fixation support, daily local massage and manipulation, the therapeutic effect is still relatively good. If the early did not find missed the best treatment period, with the growth and development to puberty, conservative treatment effect will not work.
If it is a mild xo-shaped leg, the function of the joint is not affected, and there is no pain symptoms, there is no need for treatment.
If the function is affected and the deformity is severe, surgery is considered necessary. Surgery is recommended to be carried out around puberty, the main surgical method is osteotomy and orthopedic, with steel plate internal fixation, and when the osteotomy heals, it is necessary to take out the internal fixation again, so that the shape and strength of the lower limb can be restored better.
