The Foundation: Musculoskeletal Embolization
To understand the evidence behind PFE, it helps to start with the broader category it belongs to: musculoskeletal (MSK) embolization. Embolization itself is not a new technique. Interventional radiologists and vascular surgeons have used embolization for decades to treat conditions such as uterine fibroids, liver tumors, and vascular malformations. The procedure involves delivering microscopic particles through a catheter to reduce or redirect abnormal blood flow in targeted areas.
The application of embolization to musculoskeletal pain conditions was pioneered by Dr. Yuji Okuno in Japan. His foundational insight was that many chronic musculoskeletal pain conditions — including knee osteoarthritis, frozen shoulder, tennis elbow, and plantar fasciitis — share a common feature: neovascularity. These are abnormal networks of small blood vessels that develop in and around damaged or inflamed tissue. Rather than supporting healing, these abnormal vessels sustain a cycle of chronic inflammation and pain.
By targeting and embolizing these abnormal blood vessels with microscopic particles, the procedure disrupts the chronic pain cycle at its source. This concept — now supported by a growing body of published research — forms the basis for both genicular artery embolization (GAE) for knee osteoarthritis and plantar fasciitis embolization for chronic heel pain. You can learn more about the full range of these procedures on our musculoskeletal embolization page.
Genicular Artery Embolization: The Most-Studied Application
Among all MSK embolization procedures, genicular artery embolization (GAE) for knee osteoarthritis has the largest and most mature evidence base. Multiple published studies — spanning case series, retrospective analyses, and prospective trials — have followed hundreds of patients and produced consistent findings:
- Significant pain reductionas measured by validated pain scales
- Improved physical functionand range of motion
- Sustained resultslasting well beyond the initial recovery period
- A favorable safety profilewith no major complications
This matters for anyone evaluating PFE because the two procedures share the same underlying mechanism. Both target neovascularity — abnormal blood vessels sustaining chronic inflammation — using the same image-guided embolization technique and the same category of microscopic embolic particles. The strong evidence supporting GAE provides a meaningful foundation of confidence for the application of this technology to chronic plantar fasciitis.
PFE-Specific Evidence
Research focused specifically on plantar fasciitis embolization has been growing steadily, with published case series and early clinical data showing encouraging and consistent results. While PFE is earlier in its research trajectory compared to GAE, the outcomes reported to date are compelling:
- 80–90% of patientsin published studies report significant pain reduction following PFE
- Improvements in VAS (Visual Analog Scale) pain scores— the standard validated tool for measuring pain intensity — have been documented across multiple studies
- Functional outcome measuresconsistently show improvement after the procedure
- Patient satisfaction ratingsare high, reflecting meaningful real-world improvements in daily activity and quality of life
- The procedure’s safety profileis consistent with other well-established embolization procedures
These findings come from clinical centers around the world where interventional radiologists and vascular surgeons are performing PFE and contributing to the collective evidence base. The growing number of providers performing PFE globally is itself a reflection of the clinical community’s confidence in the procedure’s mechanism and outcomes.
Understanding the Research Landscape
It’s important to understand where PFE sits in the broader landscape of clinical research. Every medical procedure moves through a progression of evidence — from early case reports and case series, to retrospective studies, to prospective trials, and eventually to randomized controlled trials (RCTs). Here is where PFE stands today:
- Current evidenceis primarily from case series and retrospective studies — the same stages that GAE progressed through before larger trials confirmed its effectiveness
- Larger prospective studies and randomized controlled trialsare underway at multiple institutions, which will provide even stronger evidence in the coming years
- Researchers and clinicians are actively publishing and presenting resultsat major radiology and vascular surgery conferences worldwide
- The clinical community’s understanding of optimal patient selection and techniquecontinues to be refined with each published study
This trajectory is typical — and healthy — for an emerging procedure built on established technology. The key point is that the evidence so far is consistently positive, and the research momentum is strong.
Trained Alongside the Pioneer of Musculoskeletal Embolization
Dr. Fox recently hosted Dr. Yuji Okuno, MD, PhD — the Tokyo-based interventional radiologist who pioneered embolization for chronic joint and soft tissue pain — at his Manhattan practice following the 2026 GEST Global Embolization Symposium. Dr. Okuno’s published research on genicular artery embolization and plantar fasciitis embolization provides much of the clinical foundation behind the procedures performed at Fox Vein & Vascular.
Key Outcome Measures in PFE Research
When evaluating PFE research, it helps to understand the specific metrics that studies use to measure success. These are the same validated tools used across foot and ankle research, allowing for meaningful comparison:
- VAS (Visual Analog Scale) pain scores— A standard 0–10 scale where patients rate their pain intensity. Studies consistently show significant drops in VAS scores after PFE.
- AOFAS (American Orthopaedic Foot & Ankle Society) scores— A composite score measuring pain, function, and alignment. Higher scores indicate better outcomes.
- FFI (Foot Function Index)— A validated questionnaire assessing how foot pain affects daily activities, including difficulty walking, standing, and climbing stairs.
- Patient satisfaction ratings— Self-reported measures of overall satisfaction with the procedure and its outcomes.
- Time to return to activity— How quickly patients are able to resume walking, work, and exercise after PFE.
- Need for repeat procedures— Tracking whether patients require additional treatment after their initial PFE.
Understanding these measures can help you evaluate PFE research with the same lens that clinicians use, giving you confidence that the reported outcomes are measured rigorously rather than anecdotally.
Safety Profile
Safety is a top priority for any procedure — and PFE’s track record is reassuring. Across published studies:
- No major complicationshave been reported in PFE-specific research
- Minor complications— such as temporary bruising at the access site or brief numbness — are infrequent and self-resolving
- The safety profile is consistent with the broader embolization safety record, a category of procedures with decades of clinical use
- The procedure requires only local anesthesiawith optional light sedation — no general anesthesia is needed
- Patients are discharged the same dayand typically return to light activity within 24 to 48 hours
Dr. Fox’s extensive training and experience as a board-certified vascular surgeon with more than 28 years of practice further minimize risk. Every PFE procedure at Fox Vein & Vascular is performed using real-time fluoroscopic imaging, ensuring precise delivery of embolic particles to only the targeted abnormal vessels.

What the Evidence Means for Patients
If you’ve been living with chronic heel pain for six months or longer and conservative treatments — stretching, orthotics, physical therapy, cortisone injections, or shockwave therapy — haven’t provided lasting relief, the evidence supports PFE as a viable next step. Here is what you should take away from the current research:
- The science supports PFE as a legitimate, evidence-backed treatmentfor chronic plantar fasciitis
- PFE is built on well-established embolization techniqueswith decades of clinical use across multiple medical specialties
- The evidence is growing and consistently positive, with no concerning safety signals
- As with any newer procedure, ongoing research will continue to refine patient selection and optimize technique — but the foundation is solid
- You don’t need to choose between “proven” and “effective.” PFE is an emerging procedure that has already demonstrated strong outcomes in every study published to date

What the Evidence Means for Referring Providers
For podiatrists and other referring providers evaluating PFE for your patients, the current evidence supports adding plantar fasciitis embolization to the treatment algorithm for refractory plantar fasciitis. Key considerations from the published literature:
Patient selection matters
The best outcomes are associated with patients who have imaging-confirmed neovascularity and documented failure of multimodal conservative care — the same patients you’ve already been managing.
The mechanism is well understood
Targeting abnormal inflammatory blood vessels with embolization is not theoretical — it’s the same approach proven effective in GAE for knee osteoarthritis.
The procedure is collaborative, not competitive
PFE is designed to work within the existing care pathway. Patients remain under your care; Dr. Fox provides vascular evaluation, candidacy assessment, the embolization procedure itself, and a written report back to your office. Patients return to you for continued podiatric follow-up after treatment.
The safety profile supports confident referral
Published data shows no major complications, and the procedure’s minimally invasive nature means minimal disruption to your patients’ lives.
Dr. Fox welcomes clinical discussions about specific patient cases. If you have a patient who fits the profile — chronic plantar fasciitis, failed conservative management, seeking alternatives to surgical release — we encourage you to reach out. You can also review our podiatrist referral guide for a detailed overview of the collaborative pathway.
