Bunion Surgery (Keller) Recovery
Keller Bunionectomy (Resection Arthroplasty)
What the operation does
The base of the big toe bone is removed, taking out the worn joint surface and leaving a gap where the joint used to be. That gap fills with scar tissue over the following months and becomes a flexible false joint. The toe ends up shorter and more mobile, and the pain of bone grinding on bone is gone because the two surfaces no longer meet.
How it differs from the other bunion operations
This is the important distinction. A standard bunionectomy or a Lapidus realigns bone and waits for it to heal. A Keller removes bone and does not realign anything. There is no bone cut healing inside your foot, which is why weight and movement come sooner here than after those operations — and why the trade-off sits elsewhere.
What you give up
Push-off through the big toe. The muscles that used to pull on the base of the toe no longer have their normal attachment point, so the toe cannot press firmly into the ground. Most people walking at ordinary speeds do not notice. Running, sprinting, and springing off that foot are affected, which is why this operation is generally chosen for people who are not asking for that.
Who it usually suits
It tends to be offered where the big toe joint is worn out and the demands on the foot are moderate — often older patients, or those for whom a longer recovery from a fusion or a realignment would be difficult. It is a shorter recovery and a smaller undertaking, deliberately.
The toe will be shorter
Removing the base of the bone shortens the toe by roughly a centimetre. It is usually noticeable if you look for it and not otherwise. Some people find the toe sits slightly raised off the ground rather than resting flat on it — a floating toe — which is generally a cosmetic matter rather than a painful one.
Pressure moving to the other toes
This is the one worth knowing about in advance. When the big toe stops taking its share of load, the smaller metatarsals behind the second and third toes take more. That can produce aching or callus under the ball of the foot, sometimes months later. It is why so much of the programme is lesser-toe and forefoot work rather than great-toe work, and why a cushioned insole often helps.
Why the exercises here look different
There is nothing healing that has to be protected, so toe movement and walking start straight away — early movement is what stops the gap stiffening into a rigid, unhelpful scar. And because push-off will not come back through the big toe, the strengthening turns instead to the calf, the lesser toes, and balance, so the foot has other ways to do the work.
The shoe and how you walk
Most people are in a flat postoperative shoe for a few weeks, largely for comfort and to protect the wound rather than to protect bone. Walking is usually allowed from the start, and the shoe generally comes off sooner than after an operation with a healing bone cut.
A pin, sometimes
Some surgeons place a temporary wire down the toe to hold it in position for a few weeks while the scar tissue settles. If yours does, it usually stays for around three weeks and is removed in clinic — a quick, if unglamorous, appointment.
Swelling
The forefoot swells and stays swollen for months, worse by evening and after time on your feet. It settles more quickly than after a bone-cutting operation but still takes considerably longer than the pain does. Elevation in the early weeks pays off later.
Pain
Usually modest, and often less than people expect from a bone operation. Most people are on simple pain relief within a week or so. Aching after a long day continues for some months and is a swelling matter rather than a healing one.
Driving
For a right foot, driving generally waits until you are out of the postoperative shoe and could brake hard without hesitating — commonly around three to five weeks, sooner than after a bunionectomy that involves a bone cut. A left foot in an automatic is usually much sooner.
Returning to work
Desk-based work is often possible within one to two weeks with the foot elevated. Work on your feet generally returns within four to eight weeks, again earlier than after a bone-cutting correction.
How the first year usually unfolds
The first two weeks centre on the wound, elevation, and getting the toe moving. From two to six weeks walking normalises and forefoot work begins. Six to twelve weeks brings calf strength and balance, which is where the foot learns to push off differently. Most everyday activity is back by around three months, with swelling and the final feel of the toe settling across the rest of the year.
Staying in touch with your care team
How this settles varies with how worn the joint was and how much of the bone was removed. Your surgeon knows those details. If something about your recovery is worrying you or does not match what is described here — including new soreness under the ball of the foot — contact your care team rather than waiting.
