Do you need an ankle fusion surgery? Ankle fusion has become a common surgical solution for ankle arthritis, but it’s obviously a big surgery with lots of things to consider before pulling the trigger. Let’s dig in.

What Does Fusing the Ankle Mean?

ankle fusionFirst, ankle fusions are typically performed for patients who have moderate to severe ankle arthritis (1). A fusion of a joint means to have the joint surfaces grow together so that the joint is fixed and doesn’t move any longer. In ankle fusion, given that there may be several joints involved including the tibio-talar, sub-talar, and talo-navicular joints, many different screws going many different directions are commonly placed. Another name for the procedure is an ankle arthrodesis. This basically means that the main ankle joints will no longer move.

Is Ankle Fusion a Major Surgery?

Given that the procedure involves placing multiple screws in different directions, the short answer is yes. Whether surgery is a big or small procedure is often defined by how commonly patients experience complications. For example, in one early study, the complication rate was a staggering 48%! (3) Another later study demonstrated an infection rate of 6%, a 10% rate of the patient requiring a second surgery to fix the first procedure, and a failure of the bones to grow together 14% of the time (4).  Hence, given that these complication rates are many times higher than other routine orthopedic surgeries like knee arthroscopy where the complication rate is about 1%, ankle fusion is major surgery (2).

How Long Does It Take to Recover from an Ankle Fusion? Does It Work?

Most patients will be on crutches for 2-3 months while the ankle fusion sites heal. That’s followed by 1-3 months in a walking boot. In younger patients, 62% of the patients operated in one review could return to work by 2 years (although many weren’t working before the surgery) (7).

At an average of 8 years after an ankle fusion, here’s what patients reported they could do (6):

  • 73% could hike for an average of 40 minutes
  • Only 40% of patients could kneel
  • 25% could jump down from steps
  • Only 17% of the patients could run a short distance (less than 100 yards)

Is Ankle Fusion Surgery Painful?

Yes, narcotic pain medications are generally prescribed to help with post-surgical pain. On average patients take narcotic pain medications for a few weeks (6). After that, usually, Tylenol is recommended. You should avoid NSAID drugs like Ibuprofen, Motrin, Aleve, Celebrex, and others as these have been shown to reduce bone healing (10).

Can You Drive a Car with a Fused Ankle?

The short answer is yes. However, realize that research shows that your braking reaction time will be slower than normal (9). However, it’s still within safe norms as defined by the US Highway Administration.

Should You Get an Ankle Fusion vs. Replacement?

As of a recent study comparing ankle fusion to ankle joint replacement, the conclusion was that due to complication rates, the routine use of ankle fusion can’t yet be recommended to treat arthritis (4). Surprisingly, the same researchers found that ankle replacement complications were more than double those experienced by patients who had ankle fusion surgery! Hence, it’s hard to recommend either surgery given that information. Other experts published on ankle replacement having a 15% complication rate, which is still very high compared to knee replacement where the complication rate is 8% (11,12).

Are There Newer and Less Invasive Options?

Percutaneous ankle arthroplasty (PAA) is a new procedure where the doctor uses x-ray guidance to inject your stem cells into the damaged joint and into weak areas of the bone. Loose ankle ligaments are also usually a problem as well, so they are often treated. The goal is to reduce pain and increase function without fusion surgery or ankle replacement. The procedure is minimally invasive and has a recovery time a fraction of what an ankle fusion would require. However, this is a procedure that is only performed by physician subspecialists using x-ray and ultrasound guidance using your own cells derived from bone marrow and is not the same as an umbilical cord injection performed blind.

Below is a video of the Percutaneous Ankle Ligamentoplasty part of the procedure (treating the loose ligaments that caused the ankle to get arthritis) to give you some sense of what this procedure looks like:

Hal’s Story

Hal was an accountant with ankle arthritis who had a local surgeon attempt a triple arthrodesis (an ankle fusion of three main ankle/foot joints). One of the screws inadvertently destroyed an artery that was keeping his talus bone alive, so the bone died off and began to collapse, causing severe ankle arthritis and disability. Hal had a PAA procedure at our Colorado office and went from having trouble walking 100 yards back to walking 18 holes at the golf course, all without additional surgery.

The upshot? An ankle fusion is a big surgery with quite a few complications and long recovery time. Few patients return to normal activities after these procedures. There may be newer treatment options for your ankle that don’t involve surgery.

    I had a close call with ankle fusion that was recommended by the Mayo Clinic orthopedics dept. The day prior to surgery I had a pre-op visit with the surgeon and only then found out that I would need 8-12 weeks recovery before I could drive or walk unassisted by crutches – no weight bearing allowed while the joints grew together. As a single guy with 6 horses to tend to that was not possible for me so I started searching for alternatives. It didn’t take long to find the Regenexx website and realize there might be an alternative for me. As a scientist I really appreciate that Dr. Centeno backs up his reports with literature citations. A visit to Pub Web to search for publications related to the stem cell procedures produced many articles that convinced me that the risk of these procedures is tiny compared to surgery. I had a same day regenexx procedure with Dr. Baumgartner in Minnesota and the results were really life changing. Within two weeks I had stopped limping my way from the truck to the convenience store counter and within 6 weeks I was back to hiking in the hills. That was about 8 years ago, I have since gone to the Caymans and have cells stored there for future use as I age. – THANK YOU REGENEXX!

      Hi Mike,
      Great to hear you’re doing so well! We are so thankful for the opportunity to help.

    Watched the video.
    How do I find out if I am candidate?
    Does one have to go to Cayman for this procedure?
    You should have my records from 2017.

    1. Regenexx Team

      Hi Edy,
      We’ll have the team contact you to set up a Candidacy review to see what’s needed in your case. This patient was treated with Regenexx-C, so that would be Grand Cayman, but most PAA procedures use Regenexx SD (same day).

Knees are the target of many common sports injuries. Sadly, they are also the target of a number of surgeries that research has frequently shown to be ineffective or minimally effective. Knee arthritis can also be a common cause for aging athletes to abandon the sports and activities they love. Regenerative procedures can be used to treat a wide range of knee injuries and conditions. They can even be used to reduce pain and delay knee replacement for more severe arthritis.

  • Knee Meniscus Tears
  • Knee ACL Tears

Hip

Hip injuries and degenerative conditions become more common with age. Do to the nature of the joint, it’s not quite as easy to injure as a knee, but it can take a beating and pain often develops over time. Whether a hip condition is acute or degenerative, regenerative procedures can help reduce pain and may help heal injured tissue, without the complications of invasive surgical hip procedures.

  • Labral Tear
  • Hip Arthritis
  • Hip Bursitis
  • Hip Sprain, Tendonitis or Inflammation
