The treatment of varicose veins of the knee mainly includes conservative treatment, surgical treatment, minimally invasive treatment and so on. 1. Conservative treatment: If the symptoms are mild and there is no willingness to operate or poor tolerance to operation, you can wear compression stockings or use elastic bandage to put pressure on the knee joint to promote blood return, and at the same time pay attention to avoiding prolonged sitting, prolonged standing and intermittent elevation of the affected limbs. 2. Surgery: Surgery can be performed when there is no contraindication to surgery, which is applicable to varicose veins and serious venous valve reflux, etc. Usually, saphenous vein ligation and stripping surgery is performed in high position. 3. Minimally invasive treatment: For early stage of mild symptoms and cosmetic requirements, sclerotherapy injection, laser closure of local blood vessels and local compression can be used. When varicose veins of the knee occur, the treatment should be standardized under the guidance of doctors.
