 This handout tells you about care after a below (BKA) or above (AKA) the knee amputation.

Care of the Incision 

  1. Look at your entire leg, front and back, each day. Use a mirror to look for skin sores, blisters, or red marks. Do not pop blisters!

  2. Wash your leg and incision everyday. You need to keep the leg clean.

    • Do not soak the leg.

    • Use warm water.

    • Use mild soaps without fragrance (Example: Dial® soap).

  3. Apply a telfa to the incision and secure with paper tape.

  4. Wear ace wraps or a shrinker sock all the time. This will compress your stump.

  5. Wear a leg protector (rigid removable dressing) as instructed by a physical therapist. It will help reduce swelling, speed up healing and shape the stump for a prosthesis.

Activity

Keep doing the exercises you learned in physical and occupational therapy. You may tire quickly as you do more. This is normal. It will lessen as you get your strength and energy back. Rest as needed but be as active as you can to maintain your strength. Activity and exercise help you get ready for a prosthesis and keeping muscle. 

Pain Control

It is normal to have pain at the incision site. Your doctor may have prescribed pain medicine to use at home. Your pain should lessen over time. Your doctor will tell you when you can use over-the-counter pain medicines. You may also have phantom sensation or phantom pain.

Phantom sensation is the feeling that you still have the amputated part (leg or toe). Often, only the furthest part is felt. It is not painful. There may be tingling, numbness, or pressure. It may go away in time or it may last through life. Most people who have an amputation have phantom sensation.

Phantom pain is actual pain (burning, cramping, squeezing, or shooting) in the amputated part. It may be present all the time or it may come and go. Phantom pain may be relieved with pain medicine. If severe phantom pain is a problem, ask your doctor for help. 

Diet

You may resume your regular diet when you return home. Decreased activity as well as some prescription pain medicines can cause constipation. 

Try to prevent constipation by eating foods high in fiber (whole grain breads and cereals, fresh fruit, and vegetables).

If these do not work, you may use an over-the-counter stool softener or laxative. If the problems do not go away, call your doctor.

Care of Your Other Leg

If you have diabetes or have peripheral vascular disease, it is important to take good care of your other leg and foot and protect it from injury. 

To care for your other leg:

  • Look at leg and foot daily. Report any sores, scratches, cracks, blisters or reddened areas, to your doctor or nurse.

  • Wash your leg and foot daily with mild soap and water. Avoid soaking. Dry well.

  • Put lotion on dry skin daily. Do not put lotion between your toes.

  • Let a doctor or nurse clip your toenails or show you how to clip toenails.

  • Wear shoes that fit well.

  • Wear white cotton or wool socks.

  • Check shoes and socks for stones, sharp items, or holes.

  • Do not use heating pads or hot water bottles on leg or foot.

  • Never go barefoot.

  • Ask for a mirror if you cannot see your foot.
