Most of this practice exists to keep you out of surgery — laser, shockwave, orthotics, and regenerative injections resolve the majority of foot pain we see. But when a bone must truly be realigned, the operation itself should disturb as little of you as possible. That’s minimally invasive surgery (MIS), and it’s what Dr. Ahn is known for.
What “minimally invasive” actually means
Instead of opening the foot with a long incision, the surgeon works through openings measured in millimeters — inserting fine, specially designed instruments with live X-ray (fluoroscopic) guidance. The surgical field is barely exposed, so the tissue around the correction is left essentially undisturbed.
The technique isn’t new — Dr. Morton Polokoff pioneered sub-dermal foot surgery in 1945 — but decades of refinement turned it into today’s state of the art. It’s also genuinely specialized: safe MIS requires extensive training, continuing education, and fellowship within the ambulatory foot surgery community. Dr. Ahn is a Fellow of the Academy of Ambulatory Foot & Ankle Surgery, an international body of more than 2,000 physicians dedicated to exactly this approach — and he has taught these techniques to other surgeons.
What it treats
Bunions, hammertoes, stiff big toe, painful calluses, bone spurs, heel pain that has failed every conservative measure, and select diabetic foot problems. Whether your case is an MIS case is what the exam and X-rays decide.
Why patients choose it
- Less injury. Millimeter incisions disturb dramatically less soft tissue than open surgery — the single biggest driver of easier recovery.
- Less pain early on. In head-to-head trials, patients who had the minimally invasive version report lower pain scores in the first days and weeks. By a year out, both groups feel about the same. The difference is in how hard the recovery is, not where you end up. In our experience, most of these patients get through that recovery on far less pain medicine than open surgery usually takes.
- Local anesthesia only. Your foot sleeps; you don’t. That removes general anesthesia risks and extends surgery to patients previously told they weren’t candidates.
- Shorter surgery. Small access means efficient procedures.
- Waking up without hardware. Corrections are typically stabilized with precise external compression dressings rather than implanted pins and screws.
- Same-day walking. Procedures are outpatient; patients ambulate immediately in a surgical shoe or boot.
- Nearly invisible scars. Millimeter incisions heal to marks most people can’t find.
What recovery looks like
You wear a bulky dressing for the first week, with a re-dress visit a few days after surgery. At one week, the dressing steps down to bandage strips, a toe separator, and a daily self-changed wrap for three to four weeks. Return to regular shoes tracks your individual healing and swelling — and because you’re walking from day one, “recovery” looks less like convalescing and more like easing back up to speed.
Surgery remains our last resort. But if your foot has earned it, this is the version of surgery worth having.
