Ankle Replacement

What this procedure is

Ankle replacement surgery, also called total ankle arthroplasty, is a procedure to replace a damaged ankle joint. During this surgery, a surgeon removes the worn-out ends of the bones that make up the ankle. These are replaced with artificial parts made of metal and a special type of plastic.

The goal of the procedure is to help the joint move smoothly again. By using these artificial parts, the surgery mimics the natural movement of your ankle. This can help you walk more easily and with less discomfort.

What it treats or fixes

This surgery is most often used to treat severe arthritis. Arthritis is a condition where the smooth cushion (cartilage) between your bones wears away, causing the bones to rub together. This can lead to significant pain, swelling, and stiffness.

Your clinician may suggest this procedure if you have:

• Osteoarthritis: Wear-and-tear that happens as people age.
• Rheumatoid arthritis: A condition where the immune system attacks the joints.
• Post-traumatic arthritis: Joint damage that develops years after a bad break or injury.

The procedure is usually considered when other treatments, like physical therapy, bracing, or medication, no longer provide enough relief.

How common it is & where it's done

While ankle replacements are not as common as hip or knee replacements, they are a well-established option for people with chronic ankle pain. Advances in technology have made these artificial joints more durable and effective than in the past.

This surgery is typically performed in a hospital or a specialized surgical center. It is done by an orthopedic surgeon, a doctor who specializes in bone and joint health. Most patients stay in the hospital for a short time after the procedure to begin their recovery under medical supervision.

Recovery: What to Expect

After your surgery, you will likely stay in the hospital for at least one night. Your ankle will be placed in a splint or a cast to keep it stable while it begins to heal. For the first few weeks, your clinician will likely ask you to keep all weight off that foot. You may need to use crutches, a walker, or a knee scooter to get around safely.

Physical therapy is a major part of recovery. A therapist will teach you exercises to improve your range of motion (how well the joint moves) and strengthen the muscles around your new ankle. Most people can begin putting some weight on the foot after a few weeks, but full recovery often takes several months.

Risks & Possible Complications

While most ankle replacements are successful, all surgeries carry some risks. Your care team will monitor you closely to prevent issues. Possible complications may include:

• Infection or problems with the skin healing around the incision.
• Blood clots in the leg.
• Damage to nearby nerves or blood vessels.
• The new joint loosening or wearing down over many years.

It is important to watch for signs that you may need extra care. You should call your clinician if you experience a high fever, sudden calf pain, or if the area around your ankle becomes very red, hot, or increasingly painful.

Outcomes & Long-Term Results

The primary goal of an ankle replacement is to reduce chronic pain and help you move more easily. Most patients find that their pain is significantly lower than it was before surgery. While the new joint may not move exactly like a natural ankle, it often provides better movement than other surgical options, such as ankle fusion.

Many modern ankle implants are designed to last 10 years or longer. To help your new ankle last as long as possible, your clinician may suggest sticking to low-impact activities like walking, swimming, or cycling rather than high-impact sports like running or jumping.

Emotional Support & Reassurance

It is completely normal to feel nervous about having a joint replacement. Taking the time to prepare your home and asking friends or family for help during the first few weeks can make the process feel much more manageable. Focusing on your long-term goals—like walking through the grocery store without pain or playing with grandchildren—can help you stay positive during physical therapy.

Your healthcare team is your best resource. They are there to answer your questions and support you as you regain your independence and improve your quality of life.

Why doctors recommend it

Doctors usually suggest ankle replacement for people with severe arthritis. Arthritis is a condition where the cartilage—the smooth tissue that cushions the joint—wears away. This can happen because of aging, an old injury, or an inflammatory disease like rheumatoid arthritis.

Your clinician may recommend this surgery if you have constant pain that makes it hard to walk or do daily tasks. It is often considered after other options, such as physical therapy, special shoes, or medicine, have not provided enough relief. While another surgery called ankle fusion is also an option, a replacement is often chosen to help keep the joint moving.

Urgent vs planned treatment

Ankle replacement is almost always a planned, or elective, surgery. It is not usually done as an emergency. Instead, it is a choice you make with your healthcare team after monitoring your symptoms over time.

Because it is planned, you have time to prepare your home and your health for recovery. Your clinician may suggest waiting until non-surgical treatments are no longer helping you stay active. This allows you to schedule the procedure at a time that works best for your lifestyle and support system.

Goals of treatment

The main goal of this surgery is to reduce or get rid of chronic ankle pain. By replacing the damaged joint surfaces with metal and plastic parts, the surgery stops the painful rubbing of bone against bone.

Other goals include:

• Improved mobility: Helping you move your foot up and down more naturally.
• Better quality of life: Making it easier to perform daily activities like walking or climbing stairs.
• Joint protection: Maintaining motion in the ankle may help prevent stress and wear on the nearby joints in the foot and leg.

Who may benefit

Ankle replacement surgery, also called total ankle arthroplasty, is often an option for people with severe arthritis that has not improved with other treatments. This includes osteoarthritis (wear-and-tear), rheumatoid arthritis (an immune system condition), or arthritis caused by a past injury. Your clinician may suggest this if your ankle pain makes it hard to walk, sleep, or perform daily activities.

The main goal of this surgery is to relieve pain while keeping the joint moving. Unlike ankle fusion, which joins the bones together and makes the joint stiff, a replacement uses artificial parts to help you maintain a more natural walking motion. This can also help protect the other joints in your foot from extra stress.

When it may not be the right option

This surgery might not be the best choice for everyone. Your care team may look for certain factors that could make the surgery less successful. For example, if you have a current infection in your ankle or bone, the surgery will usually be avoided. It may also not be recommended if you have poor blood flow to the foot or nerve damage that affects your leg muscles.

Other factors that might make a replacement difficult include:

• Severe bone loss: If the bones are too weak or damaged to hold the artificial joint.
• Significant misalignment: If the ankle is severely tilted or out of place.
• High-impact lifestyle: If you regularly perform heavy lifting or high-impact sports, a different procedure like ankle fusion might be more durable for your needs.

Questions to ask your care team

Deciding on surgery is a big step. It is helpful to bring a list of questions to your appointment to help you understand your options. You might consider asking:

• How will this surgery improve my ability to walk compared to other treatments?
• What are the specific risks based on my health history?
• How long does the artificial joint typically last?
• What kind of physical therapy will I need after the procedure?
• Are there activities I should avoid after I have recovered?
• Is ankle fusion or ankle replacement a better fit for my activity level?

In the procedure room

When you enter the procedure room, the surgical team will help you get positioned comfortably on a padded table. The staff will place small sensors on your chest and arms to track your heart rate and oxygen levels throughout the surgery. To keep the area sterile (free of germs), the skin on your leg and ankle will be cleaned with a special soap.

Your clinician may also start an IV (a small tube in your vein) to provide fluids and medicine. The team will perform a final safety check to confirm all details before the procedure begins.

High-level steps

The surgeon begins by making an incision (a surgical cut) to reach the damaged joint. They carefully remove the worn-out ends of the tibia (shin bone) and the talus (the bone that connects the leg to the foot). This removes the damaged bone and cartilage that was causing pain.

Once the damaged areas are removed, the surgeon shapes the bones to fit the new parts. These parts are usually made of metal and medical-grade plastic. A plastic piece is placed between the metal surfaces to act like natural cartilage, allowing the joint to glide smoothly. Finally, the surgeon closes the skin with stitches or staples and applies a bandage.

Anesthesia and pain control

To ensure you are comfortable and do not feel pain, your care team will use anesthesia. You may receive general anesthesia, which puts you into a deep sleep for the entire surgery. Alternatively, your clinician may use a regional block, such as a spinal or nerve block, which numbs the lower half of your body or just your leg.

Even if you are awake but numbed, you may feel some pressure or movement, but you should not feel pain. Your team will monitor your comfort level closely and can provide medicine to help you feel relaxed or sleepy if needed.

Monitoring and safety steps

Safety is a top priority during the procedure. A dedicated team member monitors your vital signs, including your blood pressure and breathing, every few minutes. This ensures your body is responding well to the anesthesia.

The surgeon may also use real-time X-ray imaging during the surgery. This helps them see exactly where the new parts are being placed to ensure they are lined up perfectly. This precision helps the new joint work better and last longer.

Immediately after the procedure

After the surgery is finished, you will be moved to a recovery room. Nurses will check on you frequently as you wake up from the anesthesia. You may feel groggy, thirsty, or notice some soreness in your ankle as the numbing medicine begins to wear off.

Your ankle will likely be placed in a splint or a cast to keep it still and protected while it starts to heal. Your clinician may check the circulation and feeling in your toes to make sure everything is healing as expected. You will receive pain medicine to help you stay comfortable during this time.

Typical procedure length

Ankle replacement surgery typically takes about two to three hours to complete. This time can vary depending on the condition of the bone and the specific type of implant being used. Your surgical team will keep your loved ones updated on your progress during the procedure.

Common approaches (open vs minimally invasive)

Ankle replacement surgery is typically performed as an "open" procedure. This means the surgeon makes an incision (cut) through the skin and muscle—usually on the front or side of the ankle—to clearly see and access the joint. According to clinical descriptions, this allows the doctor to precisely remove damaged bone and cartilage before fitting the new artificial joint.

While minimally invasive techniques using small cameras (arthroscopy) are common for other ankle problems like cleaning out scar tissue, replacing the actual joint generally requires a standard incision. This ensures the new metal and plastic components are aligned correctly for smooth movement.

Partial vs total

Most ankle replacement surgeries are considered "total" ankle replacements. In this procedure, the surgeon resurfaces the ends of both bones that make up the ankle joint: the lower leg bone (tibia) and the foot bone (talus). The goal is to replace all damaged surfaces to restore natural motion.

Partial replacement, where only one side of the joint is resurfaced, is not a standard option mentioned in most general ankle replacement resources. The procedure is designed to treat the entire joint connection so that the new parts glide against each other smoothly.

Revision or repeat procedures

Artificial ankle joints are designed to be durable, but they may not last forever. Over time, the metal or plastic components can wear out, or the implant may become loose from the bone. If the artificial joint fails or causes pain years later, a second surgery known as a "revision" may be necessary.

During a revision, the surgeon removes the old implant and replaces it with a new one. In some cases where a new replacement is not possible, the surgeon may recommend fusing the bones together instead. Regular follow-up appointments help your care team monitor the implant for signs of wear.

Tests and imaging that may be done

To plan your surgery safely, your healthcare provider needs to see the exact shape and condition of your ankle. You will likely start with a general physical exam to check your overall health and ensure you are ready for the procedure.

Your care team may also order imaging tests to look closely at your bones and soft tissues. These often include:

• X-rays: These provide pictures of your bones to show the level of damage or arthritis.
• CT scans: These create detailed images of the bone structure to help the surgeon fit the new joint.
• MRI scans: These allow the doctor to check the condition of the ligaments and tendons around the ankle.

Medication adjustments

It is important to tell your healthcare provider about everything you take. This includes prescription drugs, over-the-counter medicines, vitamins, and herbal supplements. Some substances can interact with anesthesia or affect bleeding.

Your surgeon may ask you to stop taking certain medications, such as aspirin or other blood thinners, for a short time before the procedure. Only stop taking medicines if your clinician instructs you to do so.

If you smoke, your doctor will likely advise you to stop before your surgery date. Smoking can slow down blood flow, which may delay healing and increase the risk of problems after the operation.

Day-before and day-of instructions

Your surgical team will give you a specific checklist to follow just before your appointment. Common preparations include:

• Fasting: You will usually be instructed not to eat or drink anything after midnight the night before surgery. This is necessary for your safety while under anesthesia.
• Arranging a ride: You will not be allowed to drive yourself home after the surgery. Plan ahead to have a friend or family member drive you.
• Planning for help: You may need assistance with meals and moving around for a week or two. It is helpful to arrange for someone to stay with you or check on you during your recovery.
• Assistive devices: Your clinician may suggest you bring crutches or a walker to the hospital, or they may arrange for you to receive them there.

General surgical risks

Like any major operation, ankle replacement surgery carries some general risks. These are not unique to the ankle but can happen with many types of surgery. Your surgical team takes specific steps to lower the chance of these problems occurring.

• Infection: This can happen at the skin incision or deeper inside the joint. Antibiotics are typically given to help prevent this.
• Bleeding: Some blood loss is normal, but excessive bleeding is a risk your team monitors.
• Blood clots: Clots can form in the veins of the leg after surgery. Your doctor may prescribe blood thinners or special support stockings to reduce this risk.
• Anesthesia reactions: Some patients may have a reaction to the medication used to put them to sleep or block pain.

Procedure-specific complications

There are also risks specific to the ankle joint and the artificial parts used. While your surgeon plans carefully to avoid these, it is helpful to be aware of them.

One possibility is injury to the nerves or blood vessels that run near the ankle joint. If a nerve is affected, it might cause temporary or permanent numbness or weakness in the foot. There is also a chance that the cut bone does not heal properly to the new metal and plastic parts.

Over the long term, the artificial ankle components can wear out or become loose. Because the ankle moves differently after surgery, it is also possible for arthritis to develop in the other joints surrounding the ankle.

How complications are treated

If complications do arise, there are established ways to manage them. Infections are often treated with antibiotics. If the ankle feels stiff or weak, your clinician may adjust your physical therapy plan to help improve strength and motion.

Long-term issues, such as the implant loosening or wearing out, are monitored through regular check-ups and X-rays. If the artificial joint wears out after many years, a second surgery—called a revision surgery—may be recommended to replace the old parts with new ones.

Pain control medicines

Managing comfort is a top priority after ankle replacement. Your clinician may use a combination of different medicines to help you recover more comfortably. This often starts during surgery with anesthesia (medicine that prevents you from feeling pain) or a nerve block, which numbs the nerves around the ankle area for a period of time.

After surgery, your care team will tailor a plan for you that may include:

• Acetaminophen to reduce general pain.
• Non-steroidal anti-inflammatory drugs (NSAIDs) to help with swelling and soreness.
• Prescription pain medicines for stronger relief if needed.

It is important to tell your clinician about any allergies or other medicines you take to avoid safety issues or drug interactions.

Antibiotics

Antibiotics are medicines used to prevent or treat infections caused by bacteria. To help keep the new joint safe, your clinician may give you these medicines through an IV (a small tube in your vein) just before the surgery begins.

You might also take oral antibiotics for a short time after the procedure. This helps lower the risk of germs settling near the surgical site while it heals. Be sure to inform your surgical team if you have ever had an allergic reaction to any antibiotics in the past.

Blood thinners and clot prevention

After ankle surgery, your activity level is lower than usual, which can increase the risk of blood clots. These are clumps of blood that can form in the leg veins. To help prevent this, your clinician may prescribe blood thinners (anticoagulants), which are medicines that help blood flow more easily.

Common options your clinician may consider include:

• Low-dose aspirin.
• Prescription pills or small injections under the skin.

Your clinician will decide which medicine is right for you based on your health history. Because these medicines can increase the risk of bruising or bleeding, it is important to follow the instructions exactly as provided by your care team.

Emergency warning signs

Although serious complications are rare, it is important to act quickly if they occur. Seek emergency medical care if you experience sudden chest pain or difficulty breathing. These symptoms can indicate a blood clot that has traveled to the lungs.

You should also seek immediate help if you have sudden, severe pain in your calf that comes with redness, warmth, or tenderness. This may be a sign of a blood clot in the leg.

Call your surgeon or clinic if…

Contact your healthcare provider if you notice changes in your incision or general health. Your surgeon will want to know about symptoms that could suggest an infection or nerve issue.

• Signs of infection: Call if you develop a fever or chills. Watch for redness, swelling, or heat spreading around the incision.
• Wound issues: Let your care team know if you see bleeding, pus, or fluid draining from the incision site.
• Uncontrolled pain: Contact the clinic if your pain gets worse or if your pain medicine does not help.
• Nerve changes: Report any new numbness or tingling in your affected leg or foot.

Expected vs concerning symptoms

Recovering from ankle replacement takes time. Knowing the difference between normal healing and potential problems can help you decide when to reach out.

• Expected: It is normal to have some pain and swelling after surgery. Your ankle may also feel stiff or weak as you begin to heal and move around.
• Concerning: Pain that suddenly returns or worsens after you were improving is a warning sign. You should also report if the artificial joint feels loose or unstable, or if the incision looks like it is opening.

Non-surgical treatments

Before suggesting surgery, your clinician may recommend several non-surgical options to manage pain and improve movement. These treatments often focus on reducing inflammation (swelling) and supporting the joint to make daily activities easier.

• Pain medications: Over-the-counter or prescription anti-inflammatory drugs can help manage daily discomfort and swelling.
• Physical therapy: Specific exercises can help strengthen the muscles around the ankle and improve your range of motion, which is how far you can move your joint.
• Orthotics and braces: Custom shoe inserts or ankle braces can provide extra support and take pressure off the damaged joint.
• Injections: Steroid medications injected directly into the joint may provide temporary relief from pain and inflammation.

Watchful waiting

Watchful waiting is a period where you and your clinician monitor your symptoms without starting a new major treatment. This approach is often used if your pain is manageable and does not stop you from doing your daily activities.

During this time, you might keep track of which activities cause flare-ups. If your symptoms stay the same or improve with rest and lifestyle changes, you may be able to delay surgery. Your clinician will likely schedule regular follow-up visits to see if your condition is progressing or if your mobility is decreasing over time.

When surgery becomes the best option

Surgery is usually considered when non-surgical treatments no longer provide enough relief. If your ankle pain is severe enough to interfere with sleep or makes it hard to perform basic tasks like walking or grocery shopping, your clinician may discuss surgical options.

The decision to move forward with surgery often depends on how much the ankle issues affect your quality of life. If the joint damage is advanced and methods like physical therapy or injections have failed to help, an ankle replacement may be recommended to help you move more easily and reduce chronic pain.

Hospital services that commonly perform this surgery

Ankle replacement is usually performed in hospitals or surgical centers that have a dedicated orthopedic department. This is a medical team focused specifically on bones, joints, and muscles. Many large medical centers have specialized "Foot and Ankle" programs where the staff is trained to care for patients undergoing these specific procedures.

Your clinician may perform the surgery in a main hospital or an outpatient center. These facilities provide the necessary imaging services, such as X-rays, to help the surgical team plan the placement of the new joint. They also have recovery areas where nurses monitor your progress immediately after the operation.

Patient resources and support services

Most hospitals provide resources to help you through every stage of the process. One of the most important services is physical therapy. These specialists work with you to improve your range of motion (how well your joint moves) and help you learn to walk safely on your new ankle.

Other support services often include:

• Pre-surgery classes: These sessions explain how to prepare your home and what to expect during your hospital stay.
• Pain management teams: Specialists who focus on keeping you comfortable as you heal.
• Discharge planners: Staff members who help you arrange for any medical equipment you might need at home, such as crutches or a knee scooter.

Questions for choosing where to have surgery

When deciding where to have your procedure, it is helpful to gather information about the facility's experience and support systems. You may want to ask your surgical team the following questions:

• How many ankle replacements are performed at this hospital each year?
• Is there a dedicated physical therapy team that specializes in foot and ankle recovery?
• What is the typical length of stay for patients having this surgery?
• Does the facility have a plan for coordinating my care after I go home?
• What resources are available if I have questions about my recovery during the evenings or weekends?

Conditions commonly treated by this procedure

Ankle replacement surgery, also known as total ankle arthroplasty, is primarily used to treat severe arthritis. Arthritis is a condition that causes the cartilage—the smooth, slippery tissue that cushions the ends of your bones—to wear away. When this cushion is lost, the bones may rub against each other, leading to discomfort and limited movement.

• Osteoarthritis: This is often called "wear and tear" arthritis. It can happen as people age or after many years of joint use.
• Rheumatoid arthritis: This is an autoimmune condition, meaning the body’s immune system mistakenly attacks the lining of the joints, causing damage over time.
• Post-traumatic arthritis: This type of arthritis can develop years after a significant injury, such as a broken ankle or a severe sprain.

Your clinician may consider this surgery if the damage to the joint is advanced and other treatments, such as physical therapy or bracing, have not provided enough relief.

Related symptoms people search for

People who may need an ankle replacement often experience symptoms that interfere with their daily activities. These signs can vary from person to person, but they are generally associated with the breakdown of the joint surface. Common symptoms your clinician may look for include:

• Persistent pain: Deep aching in the ankle that may feel worse when you are active or standing for long periods.
• Joint stiffness: Difficulty moving the foot up or down, which can make walking on uneven ground or using stairs a challenge.
• Swelling: Regular puffiness or inflammation around the ankle joint that does not go away with rest.
• Instability: A feeling that the ankle might "give way" or is not strong enough to support your weight.

If you are experiencing these symptoms, it is important to have a thorough evaluation. Your clinician may use imaging tests to see how much cartilage remains and to help decide if a replacement is the best option for your lifestyle.

Evidence overview

Ankle replacement surgery, also called total ankle arthroplasty, is a recognized treatment for severe ankle arthritis. Medical evidence shows that this procedure can effectively relieve pain and help patients keep their ankle joint moving. By preserving motion, the surgery often allows for a more natural walking pattern compared to ankle fusion, which locks the joint in place.

While ankle replacements are less common than hip or knee replacements, the technology has improved significantly. Studies suggest that modern artificial ankle joints can function well for 10 years or more. However, these implants are mechanical devices that can wear out over time. If an implant loosens or fails, a revision surgery may be necessary in the future.

Safety notes and individualized care

Ankle replacement is generally safe, but like all major surgeries, it carries potential risks. Your surgical team will work to minimize complications, but it is important to be aware of possible issues. Risks associated with ankle surgery may include:

• Infection or problems with wound healing
• Blood clots or bleeding
• Damage to nearby nerves or blood vessels
• The artificial joint becoming loose or the bone failing to heal to the implant
• Misalignment of the bones

This procedure is not suitable for everyone. Your clinician will review your medical history to decide if it is the right choice for you. Factors such as poor bone quality, active infections, severe ankle deformity, or poor blood flow may make the surgery risky. Your doctor will create a care plan based on your specific health needs to support a safe recovery.
