In terms of correction alone, any protrusion of the medial knee bone can be corrected. In the case of minors, there is still some room for bone growth and development, and an external fixation brace can be tailored to correct the problem. The angle of the brace can be adjusted to correct the deformity by regular review of the film. If the bone deformity is particularly pronounced in adults, the deformity can be adjusted through osteotomy surgery, which removes the excess bone. However, these treatments are based on the premise that a radiographic examination has been done in the hospital, and it is clear that the deformity of the bone is so obvious that it has reached the level of correction, and that these treatments can not be performed by judging the deformity of the bone by its appearance. The decision to do orthopedic treatment can only be made after the radiographs have been taken and it is clear that the bone has changed in these ways.
