Flexible flat feet and abducted feet can cause discomfort, pain, and difficulty with mobility. Subtalar Arthroeresis with an implant is a minimally invasive surgical procedure designed to alleviate pain and improve foot function. Here’s a detailed guide to help you understand this procedure and what to expect during recovery.
What is Subtalar Arthroeresis with Implant?
Subtalar Arthroeresis is a surgical procedure that involves inserting a small implant between the bones beneath your ankle joint. This implant reduces excessive motion in the subtalar joint, improving the position and alignment of the foot. The operation is typically performed alongside other procedures, such as Achilles tendon lengthening, to provide a comprehensive solution for foot issues.
The procedure is minimally invasive, usually taking 15 to 30 minutes, and does not require bone fixation unless additional procedures are performed.
Why Consider This Surgery?
The main goals of subtalar Arthroeresis are:
To reduce pain caused by flexible flat feet or other related conditions.
To improve foot function and overall mobility.
Advantages:
A relatively short procedure.
Reduces flattening and collapse of the foot.
Requires minimal recovery time compared to more invasive surgeries.
Risks and Considerations
While the procedure is effective for many, there are some specific risks to consider:
Implant movement or extrusion (9%).
Continued pain (6%).
Recurrence of flat foot (3%).
In some cases, implant removal may be necessary (1% - 39% depending on various studies).
Other potential complications include infection and arthritis of the ankle joint.
Your consultant will discuss these risks with you and explain how they will be managed to ensure the best outcome.
Who is a Candidate for This Procedure?
This surgery is typically recommended for individuals with:
Painful flexible flat feet.
Difficulty managing symptoms with conservative treatments.
Alternative Treatments:
Modifying activity levels.
Painkillers and anti-inflammatory medications.
Calf stretches and night splints.
Custom footwear or orthotic foot supports.
Other surgical options, such as Achilles lengthening or rearfoot osteotomy.
What to Expect During Surgery
The procedure is typically performed under local anaesthesia, ensuring you remain awake but pain-free. If preferred, sedation or general anaesthesia can also be considered. You will spend approximately three hours at the hospital, including pre-and post-operative rest periods.
A responsible adult must accompany you home and assist you during the first 24 hours after surgery.
Recovery Timeline
First 2-4 Days:
Pain is typically most intense during this period, but prescribed painkillers will help manage discomfort.
Rest is crucial. Keep your foot elevated and minimise walking.
Use crutches to avoid putting weight on the operated leg.
One Week After Surgery:
Attend a follow-up appointment for dressing changes and to check your progress.
Begin weight-bearing as advised by your surgeon.
Two Weeks After Surgery:
Sutures will be removed if necessary.
Gradually increase activity levels, following your consultant’s guidance.
6-8 Weeks After Surgery:
You should be walking normally by this point.
Some swelling and mild discomfort may persist.
8-10 Weeks After Surgery:
Rehabilitation exercises may be introduced, or you may be referred to a physiotherapist.
You may return to non-manual work; manual jobs may require more time.
Driving can resume if you can safely perform an emergency stop (check with your insurer).
12-16 Weeks After Surgery:
The foot should feel more natural, with reduced swelling.
Sporting activities can be considered depending on your recovery progress.
Six Months After Surgery:
A final review will assess long-term progress.
Swelling should be minimal, and you should experience the full benefits of the surgery.
Twelve Months After Surgery:
Full healing is achieved, and any remaining improvements will stabilise.
Planning for Recovery
To ensure a smooth recovery:
Arrange for assistance with daily tasks during the initial non-weight-bearing phase.
Follow all post-operative care instructions provided by your consultant.
Attend all scheduled follow-up appointments to monitor healing progress.
Subtalar Arthroeresis with an implant is an effective and minimally invasive option for addressing flexible flat feet and improving foot function. By following your surgeon’s guidance and adhering to recovery protocols, you can expect significant improvements in mobility and quality of life. Consult your healthcare provider to determine if this procedure is the right choice for you.
