If your heel has hurt for a year or more and a surgeon has raised the idea of an operation, you deserve straight numbers before you decide. This page explains what the operations involve, how often they work in published studies, what can go wrong and how long recovery really takes. Dr. Fox is a vascular surgeon and does not perform foot surgery, so nothing here is a sales pitch for or against it.
Who ends up having surgery
Very few people. The American Academy of Orthopaedic Surgeons (AAOS) says more than 90% of patients recover with nonsurgical treatment, and that surgery is generally saved for people who have not improved after 12 months of aggressive nonsurgical care. If you are earlier in that process, our guide to plantar fasciitis that won't go away covers the steps that usually come first.
The three operations, in plain terms
- Open partial plantar fascia release. Through an incision near the heel, the surgeon finds where the fascia attaches to the heel bone and cuts part of it to relieve tension.
- Endoscopic plantar fascia release. The same partial cut, made through smaller incisions with a small camera guiding the instruments.
- Gastrocnemius recession. An operation on the calf, not the foot. One of the two calf muscles is lengthened so the ankle bends upward more easily, which lowers the pull on the fascia. The AAOS describes it as useful for people who still cannot flex the foot well despite real effort at calf stretching.
Heel spurs are usually left alone. The AAOS notes a large spur can be removed during a release, but this is not usually done because spurs do not cause the pain.
How often does surgery work?
Most studies report that most patients improve. How satisfied they are is a different question.
| Study | Who was studied | What it found |
|---|---|---|
| Davies, 1999 (open release) | 41 patients, 45 heels, followed about 31 months | 34 of 45 heels (75.6%) were pain-free or only mildly painful. Only 20 of 41 patients (48.8%) were totally satisfied. |
| Bader, 2012 (endoscopic) | 41 patients, 49 feet, followed about 4 years | Pain resolved completely in 37 feet, decreased in 11 and increased in 1. |
| Ward, 2025 review (endoscopic) | 26 studies, 978 feet | Average foot function score rose from about 56 to about 90 out of 100. |
| Saghir, 2026 meta-analysis (open vs. endoscopic) | 19 studies, 646 patients | Both improved pain and function, with no significant difference between them in head-to-head studies. |
| Molund, 2018 randomized trial (gastrocnemius recession) | 40 patients with heel pain for over a year | Function scores rose from 59.5 to 88.0 with surgery plus stretching, versus 52.5 to 65.5 with stretching alone. |
Two cautions. First, most of the fascia release research is made up of case series without comparison groups. A 2019 review graded the evidence for endoscopic release as poor, even though results looked good, and a 2023 analysis of 17 studies called the evidence equivocal on which operation to choose. Second, results vary by surgeon and by patient. In one retrospective comparison of 60 patients, only 60% of those who had an open fascia release had a satisfactory result, compared with 95% of those who had a calf release.
What can go wrong
In the 2025 review of endoscopic release, 88 of 994 patients (8.9%) had a complication. The 2026 meta-analysis estimated complication rates of 5% for endoscopic and 11% for open release, with wide uncertainty around the open figure, and described the events as minor and temporary: numbness, wound drainage, slow healing and pain along the outer foot. The main risks to understand are these.
- Persistent or returning heel pain. This was the most common complication in the 2025 review, affecting 41 patients (4.2%). The AAOS warns plainly that surgery can result in chronic pain and dissatisfaction.
- Outer foot pain and arch flattening. The plantar fascia helps hold up your arch. Cut too much of it and load shifts to the outer edge of the foot, which surgeons call lateral column pain. In a prospective study of 47 patients, 15 of 50 feet developed this pain. Those feet had about 61% of the fascia released on average, versus about 49% in the feet that did not, and the authors advised releasing no more than half. Loss of arch height and midfoot pain are also listed as complications in a 2019 American Family Physician review.
- Nerve injury. Small nerves run close to where the fascia is cut. In the 60-patient comparison, one fascia release patient had a temporary nerve injury that resolved, and five had painful scars. Lasting nerve damage is rare but has been reported, including a case where symptoms had improved only slightly a year later.
- Wound problems. Superficial infection and slow healing are reported in small numbers.
- Calf surgery risks. For gastrocnemius recession, the AAOS says complication rates are low but include damage to the sural nerve, which supplies feeling to the outer foot and lower leg, and calf weakness.

A realistic recovery timeline
Your surgeon's own protocol decides the details, and it may differ from the figures below. These are the numbers we could find in published sources.
| Operation | Early weeks | Back to work and activity |
|---|---|---|
| Open fascia release | A 2019 review says patients are kept off the foot for about three weeks. In the 60-patient comparison, comfortable full weight on the foot took more than four weeks and regular shoes about six weeks. | Full activity may take up to three months. In the comparison study, return to work averaged about 10 to 12 weeks, with a range of 4 to 24 weeks, and sports about 16 weeks. |
| Endoscopic fascia release | Usually faster. In one large report of 652 patients, 77% were back in a regular shoe at seven days. | An early comparison found a return to regular activities about four weeks sooner than with open surgery. A 2016 comparison found better function at three months and equal results at one year. |
| Gastrocnemius recession | In the comparison study, comfortable full weight bearing came at about one week. | Work at about three weeks on average, with a range of 1 to 12 weeks, and sports at about five weeks. |
Improvement often keeps building long after the incision heals. In a small study of 11 patients after endoscopic release, the median disability score had fallen partway by three months and much further by one year. Judge the result at a year, not at six weeks.
How surgeons decide which operation, if any
- How long and how hard you have tried. Twelve months of consistent nonsurgical care is the usual bar.
- Whether the diagnosis is certain. Nerve entrapment, a stress fracture and heel pad problems do not respond to a fascia release. Imaging is often used at this stage.
- Your calf. A calf that stays tight despite stretching points toward gastrocnemius recession. The randomized trial above enrolled people with that specific finding.
- Your foot shape and job. Because a release can affect the arch, surgeons weigh flat feet, body weight and how much standing your work needs.
- Their own training. Open and endoscopic release give similar long-term results, so many surgeons use the technique they know best.
An orthopedic foot and ankle surgeon or a podiatric surgeon makes this call. Our guide to which doctor to see explains who does what.
Questions to bring to your surgeon
- Which operation do you recommend for me, and why that one?
- How much of the fascia do you release?
- When will I walk in a regular shoe, drive and return to my job?
- What share of your own patients still have pain at one year?
- Is there anything short of surgery I have not tried?
If you want to consider options before surgery
Several treatments sit between conservative care and an operation. They are compared side by side in alternatives to plantar fasciitis surgery.
One of them is plantar fasciitis embolization (PFE), the procedure Dr. Fox performs. It works through an artery and does not cut the fascia. The evidence is early: in a 2026 prospective series, 17 of 24 patients (70.8%) responded at six months, and in a 2026 retrospective series, 8 of 11 (72.7%) did. These are small studies with no comparison group. No trial has compared PFE with surgery, so no one can say which works better. See PFE vs. surgery for how the two differ, our plantar fasciitis embolization page for how it is done, and the embolization guide for the approach in general. All of our heel articles are collected in the heel pain guide.
After foot surgery: when to call right away
Call your surgeon promptly for fever, spreading redness, drainage from the wound, pain that keeps getting worse, or new numbness. Swelling, warmth or pain in the calf needs same-day attention because it can signal a blood clot. Chest pain or sudden shortness of breath is an emergency. Call 911.
Frequently Asked Questions
How long is recovery from plantar fasciitis surgery?
It depends on the operation and your surgeon's protocol. Published sources describe about three weeks off the foot and up to three months to full activity after open release, and a faster return after endoscopic release. Improvement can continue for a year.
What is the success rate of plantar fascia release?
Most published series report that the majority of patients improve, but most are case series without comparison groups. In one open-release series, 75.6% of heels were pain-free or only mildly painful, while 48.8% of patients were totally satisfied.
Can plantar fasciitis surgery flatten my arch?
It can. The plantar fascia supports the arch, and releasing too much of it is linked to pain along the outer foot and loss of arch height. One prospective study advised releasing no more than half of the fascia.
Is endoscopic surgery better than open surgery?
A 2026 meta-analysis of 19 studies found similar pain and function results, with shorter operating time and fewer complications for the endoscopic approach. Early recovery tends to be quicker with endoscopic surgery, and results at one year are similar.
Does Dr. Fox perform plantar fasciitis surgery?
No. Dr. Fox is a vascular surgeon who performs embolization. Fascia release and gastrocnemius recession are performed by orthopedic foot and ankle surgeons and podiatric surgeons.
