Ankle Surgery Risks and Complications

Ankle surgery involves repairing or reconstructing parts of your ankle joint to relieve pain, improve function, or correct deformities. While often effective, it carries potential risks and complications, such as infection, blood clots, nerve damage, or issues with healing. Understanding these possibilities helps you make informed decisions with your healthcare team.

What is Ankle Surgery Risks and Complications?

Ankle surgery risks and complications refer to the potential unwanted outcomes or problems that can arise during or after an operation on your ankle. These can range from minor issues, like temporary swelling, to more serious concerns, such as infection or nerve damage, which might require further treatment or affect your recovery.

Any surgical procedure, including ankle surgery, carries inherent risks. These risks are potential problems that could happen during the operation or while you are recovering. Complications are specific issues that occur and may affect the outcome of your surgery or your overall health. It is important to understand that while these risks exist, medical teams take many precautions to minimize them. Your healthcare provider will discuss the specific risks related to your type of ankle surgery and your personal health condition before the procedure. Common risks can include problems with anesthesia, bleeding, or infection at the surgical site. More specific complications for ankle surgery might involve issues with bone healing, damage to surrounding tissues, or persistent pain.

Why it's done

Ankle surgery is typically performed to address severe ankle pain, instability, or deformity that has not improved with non-surgical treatments. The goal is to restore function, reduce discomfort, and improve your quality of life, often due to conditions like severe arthritis, fractures, or chronic ligament damage.

People usually consider ankle surgery when conservative treatments, such as physical therapy, medications, braces, or injections, no longer provide enough relief. The decision to have surgery is often made after a thorough evaluation by an orthopedic surgeon. Common reasons for ankle surgery include repairing severe ankle fractures (broken bones), treating advanced ankle arthritis (wear and tear of the joint cartilage), or stabilizing chronic ankle instability (repeated sprains). Surgery can also correct deformities that affect how you walk or stand. For example, if you have severe ankle arthritis, the cartilage that cushions your joint may be worn away, causing bone-on-bone rubbing and significant pain. Surgery, such as an ankle fusion (arthrodesis) or ankle replacement (arthroplasty), aims to eliminate this pain and improve your ability to move, even if it means some loss of motion.

How to prepare

Preparing for ankle surgery involves several steps to ensure your safety and optimize your recovery. You will likely have medical evaluations, discuss your medications, arrange for post-surgery support, and follow specific instructions regarding food and drink before the procedure to minimize risks.

Before your surgery, your doctor will conduct a complete physical examination and may order tests like blood work, an electrocardiogram (ECG) to check your heart, or X-rays. This helps ensure you are healthy enough for surgery and anesthesia. You should tell your doctor about all medications, supplements, and herbal remedies you take, as some may need to be stopped before surgery, especially blood thinners. It is crucial to follow any instructions about eating and drinking before surgery. You will typically be asked not to eat or drink anything after midnight the night before your procedure. This helps prevent complications related to anesthesia, such as aspiration (inhaling stomach contents into your lungs). Planning for your recovery is also a key part of preparation. This might include arranging for someone to drive you home, help with daily tasks, and preparing your home environment to be safe and accessible, especially since you may not be able to put weight on your ankle for a period. Quitting smoking before surgery, if you smoke, can also significantly improve healing and reduce complication risks.

What happens during

During ankle surgery, you will receive anesthesia to prevent pain, which could be general anesthesia (putting you to sleep) or regional anesthesia (numbing a specific body area). The surgeon then makes an incision, repairs or reconstructs the ankle structures, and closes the incision, typically taking a few hours.

The surgical team will first prepare you for the procedure. This includes placing an intravenous (IV) line for fluids and medications. You will then receive anesthesia. General anesthesia means you will be unconscious throughout the surgery. Regional anesthesia, such as a spinal block or nerve block, numbs your leg while you remain awake but often sedated. Once the anesthesia takes effect, the surgeon will make an incision (cut) in your skin to access the ankle joint. The specific steps of the surgery depend on the condition being treated. For example, during an ankle fusion, the surgeon removes damaged cartilage and uses screws or plates to hold the bones together until they heal into one solid bone. For an ankle replacement, the damaged joint surfaces are removed and replaced with artificial components made of metal and plastic. After the necessary repairs or replacements are complete, the surgeon closes the incision with stitches or staples. A sterile dressing is applied, and often a splint or cast is put on to protect the ankle and keep it still during the initial healing phase. You will then be moved to a recovery area for monitoring as you wake up from anesthesia.

Recovery & timeline

Ankle surgery recovery involves several stages, typically starting with immobilization and non-weight bearing, followed by gradual weight-bearing and physical therapy. The full recovery timeline varies widely depending on the surgery type, but it often takes several months, with significant improvement seen over 6 to 12 weeks.

Immediately after surgery, your ankle will be bandaged and likely placed in a splint or cast to keep it still. You will need to keep your leg elevated to reduce swelling and apply ice as directed. Pain medication will be prescribed to manage discomfort. For the first few weeks, you will typically be advised not to put any weight on your operated ankle, using crutches or a knee scooter to move around. Physical therapy usually begins after the initial healing period, often around 2 to 6 weeks post-surgery, once your doctor determines it's safe. A physical therapist will guide you through exercises to restore range of motion, strength, and balance in your ankle. This is a critical part of recovery to regain full function. The timeline for returning to normal activities varies significantly. Light activities and some weight-bearing might be allowed after 6 to 12 weeks, but high-impact sports or strenuous work could take 6 months to a year or even longer. For example, after an ankle fusion, it can take 3 to 6 months for the bones to fully fuse, and full recovery may extend to a year. After an ankle replacement, you might be able to bear weight sooner, but full recovery and adaptation to the new joint can still take many months. Consistency with physical therapy and following your surgeon's instructions are vital for a successful outcome.

Risks & side effects

Ankle surgery, like all surgeries, carries potential risks and side effects, though serious complications are uncommon. These can include infection, blood clots, nerve damage, issues with wound healing, persistent pain, or problems with the surgical hardware, which your medical team will discuss with you.

While ankle surgery is generally safe, it's important to be aware of the potential risks. One common risk is infection at the surgical site, which occurs in about 1 to 5 people out of 100 (1-5%). Symptoms of infection include increased pain, redness, swelling, warmth, or pus from the incision. If an infection develops, it may require antibiotics or, in some cases, another surgery. Another potential complication is the formation of blood clots (deep vein thrombosis or DVT) in the leg veins. These clots can be serious if they travel to the lungs (pulmonary embolism). Your doctor may prescribe blood-thinning medication or recommend compression stockings and early movement to help prevent clots. Nerve damage, leading to numbness, tingling, or weakness in the foot, is also a risk, though often temporary. Permanent nerve damage is rare. Other risks include problems with wound healing, such as the incision not closing properly. There can also be issues with the surgical hardware, like screws or plates, which might loosen, break, or cause irritation, potentially requiring removal in a small number of cases. Persistent pain, stiffness, or limited range of motion can occur even after successful surgery. In rare instances, the surgery may not achieve the desired outcome, or the condition may recur, which could necessitate further procedures.

Success rate

The success rate of ankle surgery varies depending on the specific procedure, the underlying condition, and individual factors, but many people experience significant improvement in pain and function. For example, ankle fusion often provides good pain relief for about 80 to 90 people out of 100, while ankle replacement also shows high satisfaction rates.

The success of ankle surgery is generally measured by how well it reduces pain, improves joint function, and enhances a person's quality of life. For ankle fusion (arthrodesis), which permanently joins bones, studies show that about 80% to 90% of people achieve good to excellent pain relief and stability. While it eliminates motion at the ankle joint, it can be very effective for severe arthritis. Ankle replacement (arthroplasty) aims to preserve some motion while relieving pain. Many people report high satisfaction rates, with studies indicating that about 85% to 90% of artificial ankle joints are still functioning well 5 to 10 years after surgery. However, the long-term durability of ankle replacements can vary, and some may eventually require revision surgery. For other procedures, such as fracture repair or ligament reconstruction, success rates are also generally high, especially when followed by diligent physical therapy. Factors that can influence success include your overall health, adherence to post-operative instructions, and the severity of your initial condition. It's important to have realistic expectations and discuss the expected outcomes with your surgeon based on your specific situation.

Frequently asked questions

How long does ankle surgery typically last?

The actual surgical time for ankle surgery can vary, but it typically lasts between one to three hours. This depends on the complexity of the procedure and the specific type of ankle surgery being performed, such as a fusion, replacement, or fracture repair.

Will I need to stay overnight in the hospital after ankle surgery?

Whether you need to stay overnight depends on the type of surgery, your overall health, and your surgeon's preference. Some less complex procedures might be done on an outpatient basis, meaning you go home the same day. More extensive surgeries, like ankle replacement, often require a one- to two-night hospital stay for monitoring and pain management.

What are the signs of infection after ankle surgery?

Signs of infection after ankle surgery include increased pain, redness, swelling, warmth around the incision, fever, chills, or pus draining from the wound. If you notice any of these symptoms, contact your surgeon's office immediately, as prompt treatment is important.

When can I put weight on my ankle after surgery?

The timeline for putting weight on your ankle varies significantly based on the surgery type. Many ankle surgeries require a period of non-weight bearing, typically 2 to 6 weeks, using crutches or a scooter. Your surgeon will provide specific instructions on when you can gradually start bearing weight, often guided by X-rays showing bone healing.

Will I need physical therapy after ankle surgery?

Yes, physical therapy is a crucial part of recovery for most ankle surgeries. It helps restore range of motion, strength, and balance in your ankle. Your physical therapist will guide you through specific exercises to help you regain function and return to your daily activities safely.

Can I drive after ankle surgery?

You cannot drive while taking opioid pain medication or if your operated ankle is in a cast or brace that prevents you from safely operating the pedals. If your surgery was on your right ankle, you typically cannot drive until you are fully weight-bearing and cleared by your surgeon, which can take several weeks to months. If it was your left ankle and you have an automatic car, you might be able to drive sooner, but always consult your surgeon first.
