Bunion surgery is one of the most misunderstood operations in orthopaedics. Patients arrive expecting a quick fix and a week off work. The reality is six weeks in a special shoe, four to six months for the foot to settle, and a year for residual swelling to fully resolve. Done well, it changes your foot for the better. Done in a rush, it sets up the next problem.
What bunion surgery actually does
Hallux valgus is the proper name for a bunion. The big toe drifts toward the second toe, the joint at the base of the big toe (the first MTP joint) becomes prominent, and over years it can become painful, stiff and difficult to fit into shoes. The deformity is structural, not a problem of soft tissue or footwear alone.
Surgery realigns the bone. The most common technique is a scarf osteotomy, sometimes combined with an Akin osteotomy of the toe itself. The surgeon cuts the bone, shifts it into a better position, and holds it with screws or a small plate. For severe bunions or arthritic joints, a Lapidus procedure (fusion of a joint further back in the foot) or a first MTP fusion may be used instead. Each technique has different recovery rules. Ask your surgeon which one you had.
The first six weeks are about protecting the bone
Most patients spend the first six weeks in a stiff-soled post-operative shoe or boot, with heel-only weight-bearing for the first two to four weeks depending on the technique. The screws or plate hold the alignment, but the bone underneath has to heal. Loading it too early through the forefoot can shift the alignment before the bone has united.
Swelling is the dominant issue in this phase. The foot is the lowest point in the body when you stand, so fluid pools there relentlessly. Elevation above heart level for around 80% of waking hours in the first two weeks is non-negotiable. Ice four to six times a day. Foot pumps every hour you're awake. Patients who do this religiously have noticeably less pain and faster recovery than patients who try to push through.
What the timeline looks like
- Week 0 to 2: Post-op shoe or boot, heel weight-bearing only. Elevation, ice, foot pumps. Wound review at week two and sutures out. Drive only if it's your left foot and you have an automatic.
- Week 2 to 6: Progressive weight-bearing through the heel and outside of the foot in the post-op shoe. Hip and core work, single-leg standing on the other side. Don't waste the rest of the body waiting for the foot.
- Week 6 to 12: Surgeon review with X-ray, transition out of the post-op shoe into a wide trainer. Big toe mobility work starts in earnest. Calf raises, balance drills, gait retraining. Most patients are back to full daily walking by week ten.
- Month 3 to 6: Strength work, intrinsic foot exercises, normal shoes return slowly. Light running can usually start around month four if the bone has fully healed. Heels and pointed shoes stay off for at least six months.
- Month 6 to 12: Residual swelling resolves slowly across the back half of the year. Full return to high-impact sport and most footwear options.
The two things people skip
First, big toe mobility. The first MTP joint stiffens after surgery. If you don't work on flexion and extension daily from week six onwards, you can lose 20 to 30 degrees of range and never get it back. That stiffness shows up later as the wrong push-off pattern when you walk, which loads the second metatarsal and causes a different problem. Five minutes of toe mobility work a day for three months is the cheapest insurance you'll buy.
Second, intrinsic foot strength. The small muscles inside your foot keep the arch supported and the toes working independently. They atrophy through six weeks of boot wear. Specific intrinsic work, things like toe spreading, doming, and short-foot exercises, rebuilds them. Without it, you're more likely to develop a new foot problem within the next year.
The screws hold the bone. The rehab decides whether your foot works properly for the next twenty years.
Common mistakes
Four patterns we see at the Liverpool clinic. First, returning to normal shoes too early. The forefoot is still healing and tight shoes shift the alignment back the way it came. Second, ignoring the calf. Six weeks in a post-op shoe leaves the calf weak and the Achilles tight on both sides, but especially the operated side. Third, expecting the foot to stop swelling at six weeks. Residual swelling lasts months, sometimes a year. It's frustrating but normal. Fourth, not addressing the biomechanics that caused the bunion. If your foot mechanics drove the original deformity, you need to address those mechanics or the other foot is next.
How we structure bunion surgery rehab
We typically see bunion patients fortnightly through the post-op shoe phase, then weekly from week six when the real range of motion and strength work starts, then every two to three weeks through month three. Foot rehab is detail work. Bring your post-op shoes and your usual shoes to the assessment so we can look at the whole picture. Book a 30-minute initial during the boot phase if you can, and a 60-minute when you transition out of the post-op shoe. HICAPS on the spot for private health, Medicare EPC available if you have a GP care plan.
