Adhesive Capsulitis Embolization (ACE): FAQs
What is the ACE (Adhesive Capsulitis Embolization) Procedure?
The ACE Procedure is a minimally invasive treatment designed to relieve pain and stiffness caused by frozen shoulder (adhesive capsulitis). It works by blocking abnormal blood vessels that contribute to chronic inflammation in the shoulder capsule. By reducing this inflammation, ACE can provide rapid pain relief and help restore normal shoulder movement—often with faster results than traditional therapies like physical therapy or steroid injections.
Take control of your joint health with this proven treatment—no surgery necessary.
Understanding ACE
What is the ACE Procedure for frozen shoulder?
The ACE (Adhesive Capsulitis Embolization) Procedure is a minimally invasive treatment that blocks abnormal blood vessels fueling inflammation in the shoulder capsule, providing rapid pain relief and restoring motion.
How does ACE differ from standard treatments?
Unlike physical therapy or steroid shots, which manage symptoms, ACE treats the underlying blood vessel-driven inflammation that drives chronic pain and stiffness.
Is ACE an alternative to surgery?
Yes. ACE is often chosen by those wishing to avoid the risks, pain, and long recovery associated with traditional shoulder surgery.
Is ACE an alternative to surgery?
The embolization technique is FDA-cleared for other uses, and ACE for frozen shoulder is supported by peer-reviewed studies and used in leading centers nationwide. Ask your doctor for the latest status.

How do I find out if the ACE Procedure is right for me?
Schedule a consultation with one of our interventional radiologists or shoulder specialists. They’ll review your history and imaging, answer all questions, and help you decide the best next steps.
Procedure Details
Is the ACE Procedure painful?
No. Mild sedation and local anesthesia keep you comfortable throughout the procedure. Most patients experience minimal discomfort.
Is general anesthesia required?
No, the procedure is done with mild sedation and local anesthesia—no need for full anesthesia or a hospital stay.
How long does the ACE Procedure take?
The procedure is usually completed in about 1 hour, and you can often go home the same day.
Are there risks or side effects with ACE?
Major risks are very rare. Some patients may experience mild soreness, bruising, or temporary skin color changes at the puncture site.
Can ACE be repeated if necessary?
In rare cases where symptoms recur, the ACE procedure can be safely repeated. Most people need only one treatment.
Is ACE covered by insurance?
Adhesive Capsulitis Embolization (ACE) procedure for frozen shoulder is covered by Medicare in the United States. Several vascular and interventional radiology centers confirm Medicare and most major private insurers offer coverage for ACE when it is medically necessary—typically after conservative therapies like physical therapy and injections have failed. Coverage depends on your insurance plan and location.

Preparation for ACE
How do I find out if the ACE Procedure is right for me?
Usually, you can eat a light meal beforehand and take your usual medications unless instructed otherwise. Wear loose, comfortable clothing to your appointment.
After the Procedure
What’s the recovery time after ACE?
Recovery is fast. Most resume daily activities within 24–48 hours. Full benefits unfold over the following weeks.
Are there activity restrictions after ACE?
Most patients can return to light activity in 24–48 hours. Heavy lifting or strenuous exercise may be restricted briefly, per your doctor’s advice.
Do I need physical therapy after the procedure?
Light physical therapy is often recommended after ACE to speed recovery and maximize your results.
Outcomes and Effectiveness
How soon will I see results after ACE?
Most patients start to notice pain reduction and improved motion within days to a few weeks, with continued gains over several months.
How successful is ACE in treating frozen shoulder?
Clinical studies show 80–90% success rates for pain relief and improved mobility, even in tough cases.
Can frozen shoulder come back after ACE?
Most patients experience long-term relief, but a small minority may have symptoms recur. Repeat procedures are rare.
What happens if I don’t treat frozen shoulder?
Without treatment, frozen shoulder may eventually resolve but often takes years and leaves some permanent loss of motion. Early intervention—especially with ACE—can speed recovery and restore function.
