If it is a physiological phenomenon, no treatment is needed. 1. Flat feet: typical symptoms include inward-facing gait and ankle pain. Children can use orthopedic support or arch pads under the guidance of the doctor. If significant pain is present, non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and acetaminophen may be prescribed. If conservative treatment is ineffective and symptoms are severe, surgical treatment such as bone surgery or soft tissue transfer repair should be considered. 2. Knee inversion: common symptoms include knee pain, knee inversion deformity and figure-eight gait. For children whose epiphyses are not closed, they can try to tie their legs, exercise, or use splints or orthopedic insoles to correct the deformity. For children with closed epiphyses, surgical treatment such as high tibial osteotomy or total knee replacement should be considered. 3. However, for children under 6-8 years old with flat feet, no treatment is needed for asymptomatic children because the foot arch is still developing. For children under 2 years of age with internal derangement of the knee, observation can usually be made for the time being, and it can be corrected on its own during development.
