The methods of knee inversion correction include general treatment, etiologic treatment, surgical treatment and other treatments. 1. General treatment: Regular work and rest, ensure sufficient sleep. While protecting the knee joint, functional exercises for the affected limbs can be carried out under the guidance of doctors. 2. Etiological treatment: for example, calcium supplementation can be carried out for knee entropion caused by rickets; tumor resection can be carried out for knee entropion caused by bone tumor. 3. Surgical treatment: including osteotomy and orthopedic external fixation and knee replacement. It is mainly applied to patients whose knee inversion seriously affects the physiological function of the knee. 4.

It is recommended that the patients concerned should consult the doctor in time and choose the appropriate treatment plan under the doctor’s guidance.
