If months of stretching, shoe inserts and maybe a cortisone shot have not settled your heel, you may have been told that surgery is the next step. It is rarely the only next step. Between conservative care and a plantar fascia release sits a group of in-between treatments. They work in different ways, they are offered by different kinds of specialists, and the research behind them ranges from solid to very early. This guide lines them up side by side so you can ask better questions.
How often is surgery really needed?
Not often. The American Academy of Orthopaedic Surgeons (AAOS) says more than 90% of people with plantar fasciitis recover with nonsurgical treatment, and that surgery is generally saved for people who have not improved after 12 months of aggressive nonsurgical care.
The standard operation is a partial plantar fascia release, done through an open incision or with an endoscope. It does help some people. In a 2020 randomized trial of 30 patients, those who had an endoscopic release scored better on a foot function index at 12 months than those treated with cortisone injections and supervised strength training, although the difference was no longer statistically significant at 24 months.
The AAOS also notes that surgery can result in chronic pain and dissatisfaction, which is why it is recommended only after nonsurgical treatments have been tried. That caution is the reason the middle options below exist. For a closer look at embolization against the operation itself, see PFE vs. surgery.
The options at a glance
| Option | How it works | Evidence so far | Recovery notes from the sources |
|---|---|---|---|
| Shockwave therapy (ESWT) | Sound-wave pulses are applied through the skin to stimulate healing in the fascia | Many randomized trials. A 2024 meta-analysis of 11 trials found it reduced pain. The AAOS still calls results mixed. | No incision |
| Platelet-rich plasma (PRP) | Platelets concentrated from your own blood are injected into the fascia | A 2025 meta-analysis of 24 randomized trials (1,653 people) found better pain scores than cortisone at 3 and 6 months, but not at 1 or 12 months | Injection only. Not specified in the sources. |
| Botulinum toxin injection | Injected to relax muscle and reduce tension. The AAOS describes injection into the calf. | A 2022 meta-analysis of randomized trials found pain relief, with results that varied a lot between studies | Injection only. Not specified in the sources. |
| Ultrasonic tenotomy (Tenex) | A needle-sized probe, guided by ultrasound, vibrates to break up and remove damaged fascia tissue | Case series only, no randomized trials | Small incision. No timeline given in the sources. |
| Radiofrequency microtenotomy (Topaz) | A radiofrequency wand makes small treatment points in the fascia through the skin | Case series only (10 and 61 patients) | Not specified in the sources |
| Radiofrequency nerve ablation | Heat from a probe quiets the small nerve that carries heel pain signals | One small randomized, sham-controlled study (17 patients) plus case series | Not specified in the sources |
| Gastrocnemius recession | A surgeon lengthens part of the calf muscle to take tension off the fascia | Several small randomized trials. A 2026 meta-analysis pooled 5 trials and 150 patients. | An operation. Ask your surgeon. |
| Embolization (PFE) | A catheter in an artery delivers tiny particles to reduce blood flow through abnormal vessels around the fascia | Small case series (10 to 66 patients), no randomized trial | No incision in the heel. No standard timeline published. |
No single treatment has been shown to beat all the others. A 2026 analysis that pooled 63 randomized trials of shockwave and injection treatments concluded that the choice should be tailored to how long symptoms have lasted and what you are trying to achieve, not defaulted to one option.
Shockwave and injections
These are the least invasive steps and have the most trial data. They are usually offered by podiatrists, sports medicine doctors and orthopedic foot and ankle specialists.
Shockwave therapy. The AAOS describes it as noninvasive and low risk, and says it is sometimes tried before surgery is considered. It also says the results are mixed. If you have already tried it, our sibling guide on what to do when shockwave did not work goes deeper.
PRP. In the pooled trials, PRP did better than cortisone in the middle term, at 3 and 6 months. The AAOS notes that PRP does not carry the same risk of fascia rupture that cortisone shots do, and that more research is needed on how well it works.
Botulinum toxin. Pooled trials show pain relief, and the 2026 analysis ranked it highest for short-term pain improvement. The AAOS stresses that stretching should continue alongside any injection.
If a steroid injection was your last step, see when a cortisone shot does not work.

Needle-based procedures on the fascia or nerve
These treatments go one step further than an injection. Foot and ankle specialists perform them, usually in an office or outpatient setting.
Ultrasonic tenotomy. Often known by the brand name Tenex, this removes damaged tissue with a vibrating probe. The first report was a small prospective study of 12 patients. The longest follow-up is a 2025 retrospective series in which 91% of 58 procedures were rated satisfied or very satisfied at an average of 6.6 years. These are uncontrolled case series. We compare it directly in PFE vs. Tenex.
Radiofrequency microtenotomy. Often called Topaz, after the device. A 2008 prospective study of 10 patients reported improvement at 6 months and 1 year. In a later mailed survey, 51 of the 61 patients who replied (83.6%) were satisfied, but only 61 of 111 patients sent the survey answered, which limits what it can tell us.
Radiofrequency nerve ablation. This treats the pain signal, not the fascia. In a 2013 randomized, double-blinded study of 17 patients, those who received real treatment improved and those who received a sham did not, until they crossed over to the real treatment. That is a careful design, but a very small study.
Gastrocnemius recession: surgery on the calf, not the heel
A tight calf puts extra stress on the plantar fascia. In gastrocnemius recession, a surgeon lengthens one of the two calf muscles so the ankle can bend more freely. The fascia itself is left alone.
The AAOS says this is useful for people who still have trouble flexing the foot despite a real effort at calf stretching. In a randomized trial of 40 patients with heel pain lasting more than a year, foot function scores rose from 59.5 to 88.0 with the operation plus stretching, compared with 52.5 to 65.5 with stretching alone. The benefit was still present at a 6-year follow-up.
It is still an operation. The AAOS lists sural nerve damage and calf weakness as possible complications, at low rates.
Embolization: the vascular approach
Plantar fasciitis embolization (PFE) comes at the problem from a different direction. Long-lasting plantar fasciitis can develop small abnormal blood vessels around the irritated tissue. Using X-ray guidance, a vascular specialist threads a thin catheter into an artery and delivers tiny particles to reduce flow through those vessels. Nothing is cut in the heel.
The evidence is early, and you should know that before you consider it. In a 2026 prospective series of 24 people, 17 (70.8%) met the responder definition at 6 months. In a 2026 retrospective series, 8 of 11 treated patients (72.7%) had at least a 50% drop in pain at 6 months. These are small, uncontrolled studies. There is no randomized trial yet, and no study comparing PFE with any option in the table above.
Dr. Fox is a board-certified vascular surgeon. He performs PFE and does not perform shockwave, Tenex or foot surgery, so he will tell you honestly when one of those is the more sensible next step. You can read how the procedure is done on our plantar fasciitis embolization page, and see embolization for other joints in the embolization guide.
How to choose among them
- Confirm the diagnosis first. Several other problems copy plantar fasciitis. See conditions mistaken for plantar fasciitis.
- Match the treatment to the cause. A tight calf points toward calf-focused care. Nerve-type symptoms point elsewhere.
- Ask about the evidence. How many patients were studied, was there a comparison group, and how long were they followed?
- Ask about your own recovery. The studies we reviewed did not report standard time-off figures, so your specialist's own protocol matters.
- See the right specialist. No one clinic offers everything on this list. Our guide to which doctor to see can help.
The heel pain guide collects all of our articles on these choices in one place.
When heel pain should not wait
See a doctor promptly, and do not book an elective procedure first, if your heel pain started with a sudden pop or tearing feeling, if you cannot put weight on the foot, if the heel is hot, red or swollen, if you have a fever, or if you have numbness or burning that is spreading. These point to something other than routine plantar fasciitis.
Frequently Asked Questions
What is the least invasive alternative to plantar fasciitis surgery?
Shockwave therapy is noninvasive and needs no incision, and injections such as PRP or botulinum toxin involve only a needle. The AAOS notes that shockwave results are mixed, so it does not help everyone.
Which alternative has the strongest evidence?
Shockwave therapy, PRP and botulinum toxin have the most randomized trials, and gastrocnemius recession has several small randomized trials. Tenex, Topaz and embolization are supported mainly by case series without comparison groups.
Is embolization a replacement for surgery?
It has not been compared with surgery in any trial, so no one can say that. It is an option some people consider before surgery when heel pain has lasted many months despite conservative care and the diagnosis is confirmed.
Does Dr. Fox offer all of these treatments?
No. Dr. Fox is a vascular surgeon and performs embolization. Shockwave, Tenex, radiofrequency procedures and foot or calf surgery are provided by podiatrists, sports medicine doctors and orthopedic foot and ankle surgeons.
