Knee valgus can be corrected as follows: 1. For such deformities found in infancy and early childhood, you can first try to correct them gradually by wearing a brace and using manual massage. If the deformity is very severe at an early age, surgery can be attempted as a first stage correction. For adolescents, local epiphyseal block surgery can be used to correct the deformity. The main principle of this procedure is to slow down the growth of the epiphysis on one side of the knee joint, so that the knee joint shape can be gradually corrected. 3. For adult patients with this kind of knee deformity, only osteotomy can be performed to correct the deformity, such as wedge osteotomy or U-shaped osteotomy, to correct the knee joint deformity to some extent.
