If your baby is about to have an Achilles tenotomy for clubfoot, understanding the recovery timeline day by day will help you prepare and feel confident about what lies ahead. The Achilles tenotomy is a brief, minor procedure that produces dramatic results — but the three-week post-tenotomy casting period and the transition to boots and bar are critical stages that benefit from careful preparation. This guide covers every day from the procedure through to full recovery.
What the Tenotomy Involves
Before discussing recovery, a brief overview of the procedure itself. The Achilles tenotomy is performed at the point in the casting process when all components of the clubfoot have been corrected except the equinus (downward pointing) caused by a tight Achilles tendon. Approximately 80-90% of babies treated with the Ponseti method require this procedure.
The procedure itself:
- Performed in the clinic or a minor procedures room (not an operating theatre in most centres)
- Local anaesthetic (EMLA cream or small injection) is applied to numb the skin
- A small blade is used to divide the Achilles tendon through a tiny puncture wound (2-3mm)
- The foot is then dorsiflexed (pushed upward) to confirm complete tendon division — a palpable "pop" or "give" indicates success
- A final Ponseti cast is applied immediately in maximum dorsiflexion and abduction
- The entire procedure takes under a minute; the appointment including casting takes 20-30 minutes
Day-by-Day Recovery Timeline
Day 0: Procedure Day
What happens: The tenotomy and final cast application are completed. You'll go home the same day.
What to expect:
- Your baby may be unsettled for a few hours as the local anaesthetic wears off and they adjust to the new cast position (which holds the foot in more dorsiflexion than previous casts)
- Some babies feed and sleep normally within an hour; others are fussy for the first evening
- No bleeding should be visible through the cast — a tiny amount of blood at the puncture site is normal and is contained by the cast padding
- Give regular paracetamol (infant Calpol) as directed by your clinic team to manage any discomfort
What to do:
- Feed on demand — comfort feeding is fine
- Keep the baby in a comfortable, calm environment
- Monitor the toes for colour (should remain pink) and temperature (should be warm)
- Elevate the leg slightly if the baby is lying down, to reduce any swelling
Day 1-2: Adjustment Period
What to expect:
- Most babies settle significantly by the second day
- The puncture site is healing beneath the cast — no wound care is needed
- Sleep may be slightly disrupted on the first night but typically normalises quickly
- The baby should be feeding, having wet and dirty nappies, and generally behaving normally
When to be concerned:
- Toes that are blue, white, very swollen, or cold to touch
- Excessive, inconsolable crying beyond 24-48 hours
- Fever (temperature above 38°C)
- A foul smell from the cast
Days 3-7: Early Healing
What's happening inside: The divided ends of the Achilles tendon are beginning to form a blood clot and early scar tissue at the tenotomy site. The tendon is not yet reconnected, but the healing process is underway. Ultrasound studies show that new tendon tissue begins forming within the first week.
What to expect:
- The baby should be back to their normal routine by this point
- Paracetamol is usually no longer needed after the first 2-3 days
- The cast position (greater dorsiflexion) becomes the new normal for the baby
- Continue standard cast care: keep dry, monitor toes, protect from damage
Weeks 1-2: Tendon Regeneration
What's happening inside: The Achilles tendon is actively regenerating. New collagen fibres are being laid down across the gap between the divided ends, bridging the tendon in its lengthened position. This is a remarkable biological process — the tendon essentially regrows itself approximately 1-2 centimetres longer than it was before the tenotomy.
What to expect:
- Normal baby life continues with the cast in place
- The baby may become increasingly active and try to kick — this is normal and good, as gentle movement stimulates healing
- Keep all standard cast care precautions in place
- No clinic visit is usually needed during this period unless there are concerns
Week 3: Cast Removal and Transition
What happens: At approximately 3 weeks post-tenotomy, you return to the clinic for cast removal and the start of the boots and bar phase.
The appointment includes:
- Removal of the final cast (soaked off or cut with an oscillating saw)
- Examination of the foot to confirm correction — the practitioner will check dorsiflexion, abduction, and overall alignment
- Inspection of the tenotomy wound — by this stage, it should be fully healed, appearing as a tiny dot or barely visible scar
- Fitting of the boots and bar brace (often at the same appointment or within a day or two)
What the foot looks like:
- The foot should be in a corrected position — facing forward and upward rather than inward and downward
- The skin may be dry, flaky, or peeling after 3 weeks in a cast — this is entirely normal and resolves within a few days with moisturiser
- The calf may appear smaller than the unaffected side (in unilateral cases)
- The tenotomy site should show a tiny, well-healed mark — typically 2-3mm
Weeks 3-6: Tendon Maturation
What's happening inside: The regenerated tendon continues to strengthen and remodel. Ultrasound studies demonstrate that by 6 weeks post-tenotomy, the tendon has regained significant structural integrity, though full maturation continues over several months.
What to expect:
- The baby is now in boots and bar — full-time (23 hours/day) for the first 3 months
- The transition from casting to bracing can be a significant adjustment for both baby and parents
- The tenotomy site requires no specific wound care — just normal bathing
- The Achilles tendon area may feel slightly thicker than normal on palpation — this is the healing tendon and is expected
Weeks 6-12: Full Recovery
What to expect:
- The Achilles tendon has effectively fully healed in its lengthened position
- The baby should have adapted to the boots-and-bar routine
- Follow-up appointments (typically monthly at this stage) monitor the maintained correction
- The tenotomy scar is usually barely visible by this point
- The foot's corrected position is maintained by the brace
Common Parental Concerns During Recovery
Will the Tendon Heal Properly?
Yes. Research using ultrasound imaging has consistently shown that the Achilles tendon regenerates reliably after percutaneous tenotomy. Studies published in the Journal of Pediatric Orthopaedics demonstrate complete tendon continuity by 6 weeks, with the tendon approximately 1-2 centimetres longer than pre-tenotomy. This lengthening is the entire purpose of the procedure — it corrects the equinus that casting alone cannot fully address.
Is There a Risk of Excessive Bleeding?
Significant bleeding is extremely rare. The tenotomy is performed through a tiny incision, and the tendon itself has a relatively poor blood supply (which, paradoxically, is one reason it heals well — the low-vascularity environment promotes scar tissue formation). A small amount of blood at the puncture site is normal and is absorbed by the cast padding. If you see blood soaking through the cast, contact the clinic.
What About Infection?
Infection following percutaneous Achilles tenotomy is very uncommon (reported in less than 1% of cases). The wound is tiny and is immediately covered by the cast, which acts as a protective barrier. Signs that would warrant urgent review include fever, increasing pain after the first 48 hours, a foul smell from the cast, or redness and discharge around the cast edges.
Comparing Tenotomy Recovery to Other Clubfoot Procedures
It's worth putting tenotomy recovery in context compared to other procedures your child might encounter:
- Achilles tenotomy: Outpatient, local anaesthetic, 3-week cast, minimal post-procedure discomfort, near-invisible scar
- Tibialis anterior tendon transfer (TATT): General anaesthetic, 6-week cast, 3-4 month recovery to full activity
- Soft tissue release surgery: General anaesthetic, longer hospital stay, 6-12 week cast, 6+ month recovery
The Achilles tenotomy is by far the simplest and least invasive of the procedures used in clubfoot management, which is why the Ponseti method — with its emphasis on casting and tenotomy rather than surgery — produces such excellent outcomes with minimal morbidity.
Frequently Asked Questions
Q: How long will my baby be in pain after the tenotomy?
A: Most babies experience some discomfort for 12-24 hours after the procedure. Regular infant paracetamol (Calpol), given as directed by your clinic team, is usually sufficient. By the second day, the majority of babies are behaving normally. If your baby remains inconsolable beyond 48 hours, contact the clinic, as this may indicate a cast issue rather than tenotomy pain.
Q: Can I give my baby a bath during the 3-week cast period?
A: No full baths during the casting period. The plaster cast must stay dry. Sponge-bathe the baby, washing the upper body and nappy area while keeping the cast dry. You can cover the cast with a plastic bag secured loosely at the top for extra protection during cleaning. Full baths resume after the cast is removed.
Q: Will there be a visible scar?
A: The tenotomy wound is a tiny puncture (2-3mm). In most babies, it heals to a barely visible mark that fades to nearly nothing over the first year. By the time the child is walking, the scar is typically indistinguishable from normal skin. This is one advantage of the percutaneous technique used in Ponseti tenotomy versus open surgical approaches.
Q: What happens if the tendon doesn't heal?
A: Non-healing of the Achilles tendon after tenotomy is exceptionally rare in published literature. The regenerative capacity of the neonatal Achilles tendon is reliable. In the extremely unlikely event of healing problems, the treating team would assess and manage accordingly, but this is not a scenario parents need to worry about in practice.
Q: When will my baby start wearing boots and bar after the tenotomy?
A: The boots and bar are fitted when the post-tenotomy cast is removed at approximately 3 weeks. Some centres fit the brace the same day; others schedule a fitting appointment within 1-2 days. The transition from cast to boots and bar is a significant moment — you're moving from active correction to maintenance. Your clinic team will instruct you on how to apply, remove, and manage the brace.
