Knee valgus, in children aged 2-3 years, usually recovers around the age of six and does not require special treatment, while other patients require further treatment, as follows: First, no treatment required: children aged 2-3 years with knee valgus of unknown origin can gradually recover around the age of six and therefore do not require special treatment. Second, treatment is needed: The presence of claudication, knee inflammation, and joint deformation can lead to accelerated joint degeneration, so knee valgus needs to be treated at this time, and the main treatment methods include orthopedic, brace fixation, and orthopedic surgery. Through early diagnosis and treatment, knee valgus can be corrected, knee function can be protected, and serious changes in knee force lines can be avoided, thus allowing the patient to live and work smoothly.
