Achilles Tendinopathy Embolization

Advanced, Minimally Invasive Relief for Chronic Achilles Tendon Pain

If chronic Achilles tendon pain is limiting your mobility and activity level, and you have not found relief from conservative treatment, Achilles Tendinopathy Embolization (ATE) may be the breakthrough, non-surgical treatment you have been looking for. This innovative, minimally invasive procedure can provide meaningful, lasting pain relief without surgery.

Understanding Achilles Tendinopathy

Achilles tendinopathy is one of the most common tendon conditions affecting the lower extremities. It occurs when the Achilles tendon—the band of tissue connecting the calf muscles to the heel bone—becomes degenerated from repetitive stress, leading to pain, stiffness, swelling, and reduced function.

But chronic Achilles pain is more than just “wear and tear.” Research has shown that chronic inflammation and abnormal blood vessel growth (neovascularity) around the degenerated tendon play a critical role in driving pain—and this is exactly what ATE targets.

How Common Is Achilles Tendinopathy?

Achilles tendinopathy is a common condition affecting both athletes and non-athletes:

• 43% of elite track and field athletes have experienced Achilles tendinopathy
• 65% of cases in the general population are not related to sports
• 24-Month follow-up data confirm durable results
• Both athletes and non-athletes are commonly affected

Achilles tendinopathy often results from overuse and repetitive stress, but can also develop in individuals without a history of athletic activity.

Common Symptoms

• Pain and stiffness along the Achilles tendon, especially in the morning
• Pain that worsens with running, jumping, or climbing stairs
• Tenderness and swelling along the back of the ankle
• A thickened or nodular area of the tendon
• Reduced ankle flexibility and strength
• Pain that limits athletic performance or daily activity

For many patients, these symptoms progressively worsen over time, leading to decreased activity, difficulty with exercise, and a significant decline in quality of life.

What Is Achilles Tendinopathy Embolization (ATE)?

Achilles Tendinopathy Embolization—also known as Achilles tendon embolization or transarterial embolization (TAE)—is an innovative, image-guided endovascular procedure that addresses one of the key drivers of chronic Achilles pain: the abnormal blood vessels (neovascularity) that form around the degenerated tendon.

These tiny, abnormal vessels deliver inflammatory chemicals directly to the tendon, fueling a cycle of chronic pain and degeneration. ATE works by selectively blocking these abnormal vessels using microscopic particles delivered through a tiny catheter—reducing inflammation at its source while preserving normal blood flow to the tendon.

The result: significant pain relief, improved function, and a better quality of life—without surgery, without incisions, and without a lengthy recovery. For many patients, ATE serves as an effective alternative to Achilles tendon surgery and a non-surgical treatment for chronic tendon pain.

Proven Results Backed by Clinical Evidence

ATE is backed by multicenter clinical studies with follow-up extending to 24 months:

81.7%  clinical success rate (≥50% pain reduction) at 12 months in published studies

6.7 to 1.5  average pain score improvement (NRS, 0–10 scale) over 24 months

Same-Day  outpatient procedure with rapid recovery

Key Clinical Findings

• In a multicenter study of patients with chronic Achilles tendinopathy, pain scores improved from an average of 6.7 to 1.5 over 24 months of follow-up, with patients reporting meaningful improvements in both pain and function.
• ATE has consistently demonstrated a high technical success rate with a strong safety profile across published studies.
• Functional scores (VISA-A), a validated measure of Achilles tendon health, improved from an average of 48.4 to 82.2 in published studies.
• Clinical success, defined as a 50% or greater reduction in pain scores, was achieved in 81.7% of patients at 12 months.
• ATE has been shown to be effective for both athletes and non-athletes with chronic, treatment-resistant Achilles tendinopathy.
• In published studies, results have proven durable over time, with many patients avoiding the need for surgical intervention.

Clinical research shows that ATE is an effective option for patients with chronic Achilles tendinopathy who have not responded to conservative treatments—offering meaningful relief for both athletes and everyday patients.

ATE vs. Achilles Surgery: How They Compare

ATE is not a replacement for Achilles tendon surgery — it is an alternative for patients who are not ready for, or want to avoid, a surgical procedure:

Benefits of ATE

No Surgery, No Incisions. ATE targets the inflammatory source of Achilles pain without cutting into the tendon.

Outpatient Procedure. Go home the same day—typically within just a few hours.

Rapid Recovery. Resume all normal daily activities within 24 hours in most cases.

Lasting Relief. Published studies show sustained pain relief through 24 months of follow-up.

Avoid or Delay Surgery. ATE offers an effective option for patients who want to avoid or postpone Achilles tendon surgery.

Precision, Image-Guided Treatment. Advanced imaging technology allows for highly targeted treatment of only the abnormal vessels contributing to pain.

Repeatable. ATE can be repeated if needed, without the complexity of revision surgery.

What to Expect

Before Your Procedure

• Comprehensive consultation to evaluate your Achilles pain, imaging, and treatment history
• Review of ultrasound or MRI to confirm the diagnosis and suitability for ATE
• Discussion of your pain management goals and expected outcomes

During the Procedure

• A tiny access point is created at the ankle or groin — no incision at the Achilles tendon itself
• A microcatheter is guided to the small arteries supplying the Achilles tendon using real-time imaging
• Microscopic particles are delivered to block abnormal inflammatory vessels
• The procedure typically takes 30–60 minutes
• You remain comfortable under moderate sedation, performed under the supervision of a board-certified anesthesiologist

After the Procedure

• You go home the same day
• Resume all normal activities within 24 hours
• Pain relief may begin within weeks, with continued improvement over several months
• Continued improvement in tendon comfort and function over time as inflammation subsides
• No physical therapy required (though it may complement results)

Is ATE Right for You?

ATE may be an excellent option if you:

• Have chronic Achilles tendon pain lasting three months or longer
• Have not found adequate relief from physical therapy, medications, or injections
• Are not ready for or wish to avoid Achilles tendon surgery
• Want a minimally invasive, outpatient solution with rapid recovery
• Are an athlete or active individual looking to return to sport or activity
• Have other health conditions that make surgery high-risk
