Clubfoot is treated primarily through a nonsurgical approach called the Ponseti method, which uses a series of gentle stretches and plaster casts to gradually reshape the foot over four to six weeks. Most cases are identified either during a prenatal ultrasound (which can detect the condition as early as 16 weeks with about 86% accuracy) or at birth, and treatment typically begins within the first week or two of life.
The Ponseti Method: How It Works
The Ponseti method is the gold standard for clubfoot correction worldwide. The process starts with a specialist gently stretching and manipulating the baby’s foot to loosen the tight tissues pulling it inward and downward. After each manipulation, a long-leg plaster cast is applied from the toes to just above the knee to hold the foot in its newly corrected position.
The cast is removed and reapplied every one to two weeks, with the foot stretched a little further each time. On average, five casts are needed to fully correct the foot, and the entire casting phase takes roughly four to six weeks. The process is painless for most infants, especially when started in the first few weeks of life while the tendons and ligaments are still very flexible.
The Achilles Tendon Release
After the casting phase, most babies still have tightness in the Achilles tendon at the back of the ankle. A small outpatient procedure called a tenotomy is performed in 80 to 90 percent of cases to release this tension. The doctor makes a tiny cut in the tendon under local anesthesia, and a final cast is applied for about three weeks while the tendon heals at its new, longer length. Parents sometimes worry about this step, but the tendon regenerates quickly in infants, and the procedure takes only a few minutes.
Bracing: The Longest Phase
Once the casts come off, the real commitment begins. Without bracing, the foot will almost certainly revert to its original position. The brace consists of a pair of small shoes (or boots) attached to a metal bar that holds the feet apart at a set angle.
For babies whose feet are corrected in the first few months of life, the bracing schedule starts at 23 hours a day for three months. From there, wear time gradually decreases: roughly 20 to 22 hours for one month, 18 to 20 hours the next month, then 16 to 18, and finally 14 to 16 hours. Once the child is walking full-time, bracing drops to nighttime and nap time only, about 12 to 14 hours a day, and continues until age four or five.
For babies who finish casting later (around eight or nine months), the schedule is slightly compressed, starting at 18 to 20 hours a day for two months before transitioning to the standard nighttime protocol. Either way, the bracing phase lasts years, not weeks, and sticking with it is the single most important thing parents can do to prevent the foot from turning back in.
Relapse: How Common and What to Watch For
Even with successful initial correction, somewhere between 19 and 40 percent of children treated with the Ponseti method experience some degree of relapse. Most relapses happen in the first few years, often linked to inconsistent brace use.
There are three key signs parents should watch for:
- Weight on the outside of the foot. If your child walks on the outer edge of the sole rather than flat, the foot may be turning back.
- The foot slipping out of the brace boot. A boot that comes off regularly can be the first sign of mild recurrence, because the foot is changing shape enough that the boot no longer fits snugly.
- The heel turning inward or outward. Any visible shift in heel alignment warrants a call to your child’s orthopedic specialist.
Catching a relapse early makes a big difference. Mild recurrences can usually be corrected with a few additional casts and possibly a minor procedure, rather than major surgery.
The French Functional Method
An alternative to the Ponseti method, the French functional method relies on daily physical therapy sessions for the first three months instead of serial casting. A therapist stretches and manipulates the foot, then uses taping and splinting to hold the correction between sessions. After the initial intensive phase, the child transitions to nighttime splinting.
This approach requires significantly more clinic visits and access to a therapist trained specifically in the technique, which limits its availability. Outcomes are generally comparable to the Ponseti method for mild to moderate cases, but most orthopedic centers around the world default to Ponseti because it requires fewer appointments and is easier to standardize across providers.
When Surgery Is Needed
Surgery is reserved for feet that don’t respond to casting or that relapse despite proper bracing. Some children who had a good initial correction still develop a residual inward turn by age three to five, and a minor surgical procedure can address this. In rare cases, particularly when clubfoot is part of a broader genetic syndrome or an unusually rigid deformity, more extensive surgery on the bones, tendons, and joints may be necessary during infancy.
The goal of surgery is always to achieve a foot that sits flat on the ground and functions well for walking and running. Recovery depends on the extent of the procedure. Minor tendon releases may involve a few weeks in a cast, while more complex reconstructions can require several months of casting and physical therapy before the child is back on their feet.
What Happens Without Treatment
Left untreated, clubfoot does not resolve on its own. Over time, the child learns to walk on the top or outer edge of the foot rather than the sole. The skin in those areas develops thick calluses from bearing weight it was never designed to handle. Walking is possible, but it becomes increasingly painful and limited as the child grows, and the abnormal gait puts stress on the ankles, knees, and hips.
Even adults with neglected clubfoot can sometimes still benefit from the Ponseti method. A case report documented successful correction in a 26-year-old patient who had walked on the tops of his feet his entire life. Results in adults are less predictable than in infants, but the fact that correction is possible at any age underscores how effective early treatment really is. Starting in the first weeks of life, when the tissues are most pliable, gives the best chance of a fully functional foot with no lasting limitations.
