Above Knee Amputation and What to Expect Through Recovery
It is normal to feel frightened and unsure when an above knee amputation becomes part of your future. Whether the surgery is planned or follows a sudden injury, it reshapes how you picture the months ahead.
This guide walks you through why an above knee amputation happens, what the surgery and recovery involve, and how rehabilitation, prosthetic fitting, and daily life unfold in the year that follows.
You can read this at your own pace and return to it as often as you need.
What You Will Learn in This Article
- The medical reasons an amputation is performed above the knee rather than below it.
- What the surgery, hospital stay, and first weeks of healing actually involve.
- How rehabilitation, prosthetic fitting, and daily life progress over the first year.
Why an Above Knee Amputation Becomes Necessary
An above knee amputation is usually performed when poor blood flow, severe infection, trauma, or cancer makes the lower leg impossible to save, and the surgery is done above the knee to reach healthy tissue.
Learning why an above knee amputation is being recommended can be painful, especially when it follows months of trying to save the leg.
Many people reach this point only after other options have been exhausted. The decision is rarely sudden, and your care team does not make it lightly.
An above knee amputation, also called a transfemoral amputation, removes the leg through the thigh bone above the knee joint. Surgeons choose this level when the tissue below it cannot heal or survive.
Several conditions can lead to this surgery.
- Peripheral vascular disease – Poor blood flow, also called peripheral artery disease, is the most common cause and accounts for roughly 70 to 85 percent of above knee amputations.
- Diabetes complications – Ulcers, infections, and tissue death linked to long-term diabetes can spread beyond what doctors are able to treat.
- Severe infection – An infection that does not respond to antibiotics can become life-threatening if the limb is not removed.
- Trauma – A serious accident can damage the leg beyond what surgery can repair.
- Cancer – A tumor in the bone or soft tissue of the thigh or knee sometimes requires amputation.
Your surgeon chooses the amputation level based on where the tissue is healthy enough to heal. When poor blood flow or infection makes a below knee amputation unsafe, operating above the knee gives the residual limb the best chance to heal well.
What Happens During Above Knee Amputation Surgery
Above knee amputation surgery usually takes under two hours, and most people stay in the hospital for several days to two weeks afterward.
The thought of the surgery itself can be one of the most frightening parts of the journey.
That fear is something almost everyone facing this operation feels. Knowing what happens during and right after surgery can make it feel less unknown.
During the operation, the surgeon removes the leg above the knee and shapes a residual limb. The residual limb is the part of your leg that remains after amputation. Muscle and skin are shaped into a padded flap that covers the end of the thigh bone, and the bone edges are smoothed.
Here is what the surgery and early hospital stay usually involve.
- Length of surgery – An above knee amputation often takes 45 to 90 minutes, though this varies with your health and the reason for the surgery.
- Anesthesia – You will be under general or regional anesthesia, so you will not feel the procedure.
- Hospital stay – Most people stay in the hospital for 5 to 14 days while pain is managed and early healing is monitored.
- Infection prevention – Antibiotics are given to lower the risk of infection in the healing limb.
Waking up after surgery marks the start of recovery. From the first day, your care team focuses on managing your pain and protecting the healing limb.
The First Weeks of Healing
The first weeks focus on wound healing, swelling control, and keeping your hip straight, since a tight hip can make a future prosthetic leg difficult to fit.
The first weeks at home can feel raw and uncertain. You are managing pain, a changed body, and a long list of new instructions all at once.
This stage is hard for almost everyone. Healing is slow by nature, and feeling overwhelmed does not mean anything is going wrong.
Your residual limb needs time to heal before any prosthetic work can begin. Swelling has to come down, and the skin must close and stay healthy. Your care team may use a shrinker, which is a tight elastic garment that shapes the limb and controls swelling.
A few priorities shape these early weeks.
- Wound and skin care – Keeping the incision clean and watching for redness, warmth, or drainage that could signal infection. Careful residual limb care protects the skin you will depend on once a prosthesis is fitted.
- Swelling control – Wearing a shrinker or compression wrap exactly as your team directs.
- Pain management – Treating both incision pain and phantom limb pain, which is pain that feels as though it comes from the leg that is no longer there.
- Hip positioning – Protecting the position of your hip, which is one of the most important habits of this whole stage.
After an above knee amputation, the hip can tighten into a bent position if it is not stretched and positioned well. This is called a hip flexion contracture, and once the hip stays bent beyond about 15 degrees, fitting a prosthetic leg becomes much harder.
Protect Your Hip Position
Avoid placing a pillow under your thigh, and avoid sitting for long unbroken stretches. When your care team approves it, lying flat on your stomach for short periods each day helps keep the hip straight and ready for a future prosthesis.
Uneven progress is expected. Some days will feel like steps backward, and that is a normal part of healing rather than a sign of failure.
Rehabilitation and Rebuilding Your Strength
Rehabilitation rebuilds the strength, balance, and endurance you need to move safely, and it begins well before a prosthetic leg is ever fitted.
Rehabilitation can feel slow and tiring, especially when progress is measured in small movements rather than big milestones.
That pace is normal. Recovery after an above knee amputation is built from many small gains, and most people find their stamina returns gradually.
Rehabilitation is the structured program of exercises and training that rebuilds your physical function after surgery. A physical therapist leads it, and it starts with simple movements long before you stand on a prosthesis.
Early rehabilitation usually includes several kinds of work.
- Range of motion – Gentle stretching that keeps your hip and remaining joints flexible.
- Strengthening – Building the hip, core, and arm muscles you will lean on for balance and transfers.
- Transfers and mobility – Learning to move safely between the bed, a chair, and a wheelchair.
- Endurance – Rebuilding the stamina that surgery and bed rest drain away.
Walking with an above knee prosthesis takes far more energy than walking did before surgery. This is a real physical difference, not a question of effort or willpower.
This is why building strength and endurance early matters so much. Working with a therapist who specializes in prosthetic physical therapy helps prepare your body for that demand before you ever stand on a prosthetic leg.
Going slowly here is not lost time. Every bit of strength you build now makes learning to walk later more manageable.
Getting Fitted for a Prosthetic Leg
Once your residual limb has healed and stabilized, a prosthetist fits you for an above knee prosthetic leg over a series of appointments.
The idea of being fitted for a prosthetic leg can stir both hope and worry. You may wonder whether it will be comfortable, or whether you will be able to manage it.
Those questions are normal, and you are not expected to have the answers yet. The fitting process is designed to move at a pace your body sets.
A prosthetist is the specialist who designs, builds, and fits your prosthesis. For an above knee amputation, the prosthesis includes a socket that fits over the residual limb, a knee unit, and a foot.
Getting fitted usually follows a series of steps.
- Readiness check – Your prosthetist confirms the limb has healed, the swelling is stable, and the skin is sound.
- Casting or scanning – A mold or digital scan of the residual limb is taken so a custom socket can be built.
- Test socket – A trial socket is fitted and adjusted until the fit is comfortable and secure.
- Alignment and training – The knee and foot are aligned, and you begin learning to stand and step.
This is the stage that the wider process of getting your first prosthetic covers in detail, from the first appointment through your first supported steps.
The components and choices specific to an above knee prosthetic leg, including the type of knee unit, depend on your activity level and your goals. Some knees are mechanical, while others are microprocessor-controlled, which means a small computer adjusts the knee as you move.
There is no fixed timeline you must hit. A prosthesis that fits well and feels stable is worth the extra appointments it takes to get there.
Daily Life After an Above Knee Amputation
Daily life gradually reshapes around new routines for moving, managing energy, and adjusting emotionally, and most people rebuild a full and active life.
Adjusting to daily life after an above knee amputation can feel like learning your own home again. Familiar tasks now take planning.
Every amputee goes through this relearning. It is not a sign that you are failing to cope; it is the ordinary work of adapting.
Daily life changes across several areas.
- Moving around – Many people use a combination of a prosthesis, a wheelchair, and walking aids like crutches or a cane, depending on the day and the distance.
- Energy management – Because walking takes more effort, pacing tasks and resting between them protects your stamina.
- Home setup – Grab bars, a shower seat, and clear floor space make daily routines safer.
- Emotional adjustment – Grief, frustration, and changes in body image are common, and they deserve as much care as the physical healing.
Many people experience grief after limb loss, including sadness, anger, and a sense of mourning the body they had. These feelings are a normal response, not a weakness.
Support helps carry the weight of that adjustment. A counselor, a peer support specialist who has lived through limb loss, or an amputee support group can each give you a place to process what you are carrying.
Your new normal takes shape through steady adjustments that fit your life. Both the harder days and the easier ones are part of it.
The Cost of Care and Where to Find Help
An above knee amputation and the prosthetic care that follows are expensive, but Medicare, Medicaid, the VA, private insurance, and nonprofit programs cover much of the cost.
The financial side of an above knee amputation can feel daunting, especially while you are still healing.
This worry is common, and you do not have to solve it alone or all at once. Hospitals and prosthetic clinics handle these questions every day.
Prosthetic legs in the United States typically range from $5,000 to $70,000, depending on the components and the knee unit. An above knee prosthesis sits toward the higher end because the knee adds cost.
Here is what most amputees explore for coverage.
| Source | What It Covers | How to Apply |
|---|---|---|
| Medicare Part B | 80% of approved costs for a medically necessary prosthesis, after the annual deductible. | Ask your doctor for a written prescription and use a Medicare-approved supplier. |
| Medicaid | Varies by state, often covers the remaining costs after Medicare or full cost for low-income enrollees. | Apply through your state Medicaid office. |
| VA | Full prosthetic coverage for eligible veterans through a VA prosthetics program. | Enroll in VA health care and request a prosthetics referral. |
| Private insurance | Most plans cover prostheses, often with prior authorization. | Review the durable medical equipment section of your policy. |
| Nonprofit grants | Help with costs that insurance does not fully cover. | Ask your prosthetist or hospital social worker for referrals. |
You do not have to manage this paperwork by yourself. A hospital social worker can help you map out your coverage, and several nonprofit programs exist to connect amputees with financial assistance for prosthetic care.
Start with one call, like asking your clinic which plans they accept. One step at a time is enough.
Moving Forward After Limb Loss
An above knee amputation reshapes your life, and with time, rehabilitation, and support, most people rebuild independence and a life that feels like their own.
An above knee amputation is a major change, and the path from surgery through healing, rehabilitation, and prosthetic fitting unfolds over a year or more.
There is no schedule you are failing to keep. Progress comes in small, steady steps, and the harder days do not erase the ground you have gained.
Your care team, your loved ones, and other amputees who have walked this road are all part of what carries you forward.
Take one step. Ask for support. Keep moving forward.
Frequently Asked Questions
An amputation is done above the knee when the tissue below it cannot heal or survive, usually because of poor blood flow, severe infection, trauma, or cancer. Surgeons always try to save the knee joint when it is safe, since keeping the knee makes walking with a prosthesis easier. The level is chosen to reach healthy tissue that can heal well.
Most people stay in the hospital for 5 to 14 days, then spend several months on wound healing, limb shaping, and rehabilitation. Prosthetic fitting can take up to a year, and a full return to regular activity often takes a year or more. Your timeline depends on your overall health, the reason for surgery, and how your limb heals.
Many people walk again with an above knee prosthesis, though it takes training and stamina because the prosthesis has no natural knee. Walking with an above knee prosthesis uses 60 to 100 percent more energy than walking without an amputation, so rehabilitation focuses on building strength and endurance. Your physical therapist and prosthetist will help you set realistic, personal goals.
Protecting the position of your hip is one of the most important habits in the first weeks. If the hip tightens into a bent position, called a hip flexion contracture, fitting a prosthetic leg later becomes much harder. Avoid placing a pillow under your thigh, avoid long unbroken sitting, and follow your care team's positioning and stretching instructions closely.
Medicare Part B usually covers 80 percent of approved costs for a medically necessary prosthesis after the deductible, and Medicaid, the VA, and most private insurance plans also cover prosthetic care, with details that vary by plan. Prosthetic legs can range from 5,000 to 70,000 dollars, so confirming coverage early matters. A hospital social worker or your prosthetic clinic's billing coordinator can help you understand what your plan covers.
