Key Takeaways
- An adult acquired flat foot can develop gradually over time, but it can also be acute, as the tendons, ligaments, and joints that hold up the arch of the foot weaken or tear.
- The most common cause is posterior tibial tendon dysfunction, but trauma, arthritis, and certain medical conditions can also play a role.
- Orthotics, supportive shoes, physical therapy, and bracing help many patients, but symptoms can worsen if the underlying problem progresses.
- Surgery is generally considered when pain, deformity, and loss of function continue despite a meaningful trial of nonsurgical care.
- Buffalo Orthopedics, led by Dr. Parentis with 25 years of orthopedic expertise, evaluates and treats adult flat foot at convenient locations in Williamsville and Orchard Park. Request an appointment to talk through your options.
Why Flat Feet in Adults Are Different
Many adults with flat feet have lived with them since childhood and never had a problem. Others develop a flat foot gradually or even suddenly as part of an adult-acquired condition, which results from damage or injury to the posterior tibial tendon, where the arch of the foot collapses over time. These two situations look similar on the outside but are very different on the inside.
Adult-acquired flatfoot is most often caused by problems with the posterior tibial tendon, a structure that runs along the inside of the ankle and helps support the arch. When this tendon becomes inflamed, stretched, or torn, the arch can either slowly drop or quickly drop, depending on the damage to the tendon, and the foot then painfully rolls inward.
At Buffalo Orthopedics, Dr. Parentis evaluates flat foot pain individually rather than assuming every flat foot needs the same treatment.
Causes of Adult Flat Foot Pain
Several conditions can lead to adult flat foot or flat foot pain, including:
- Posterior tibial tendon dysfunction (PTTD), the most common cause in adults.
- Arthritis of the joints in the midfoot or hindfoot.
- A ligament injury or sprain that disrupts the supports of the arch.
- Trauma, including fractures around the foot and ankle.
- Inflammatory conditions such as rheumatoid arthritis.
- Charcot foot is a serious condition that can affect patients with diabetes and neuropathy.
- Symptoms can start subtly, with pain along the inside of the ankle or arch after long walks or hours on your feet, and can progress to visible flattening of the arch and an outward roll of the heel. They can also progress quite rapidly if the tendon is acutely torn.
Progressive Symptoms to Watch
Adult flat foot tends to develop in stages. The Cleveland Clinic notes that symptoms often worsen over months or years if the underlying tendon or joint problem is not addressed.
Common progressive symptoms include:
- Aching or burning pain along the inside of the ankle or arch
- Swelling around the inside of the ankle
- A noticeable drop in the arch when standing
- The heel rolling outward when viewed from behind
- Difficulty rising onto your toes on the affected side
- Pain that shifts to the outside of the ankle as the foot collapses further
- Stiffness in the midfoot and hindfoot
- Trouble walking long distances or on uneven ground
Catching these symptoms early matters. A foot that has only mild flexibility loss and tendon irritation has more nonsurgical options than a foot that has become rigid and arthritic.
When Orthotics Aren't Sufficient
For many patients, the first line of treatment is conservative care. This may include:
- Custom or prefabricated orthotics to support the arch and offload the posterior tibial tendon.
- Supportive, stable footwear with a firm heel counter and adequate arch support.
- Activity modification to limit prolonged standing, high-impact activity, and uneven terrain during flare-ups.
- Physical therapy focused on calf flexibility, posterior tibial tendon strengthening, and overall lower-extremity mechanics.
- Anti-inflammatory medication when appropriate.
- Bracing, including an ankle-foot orthosis (AFO) in more advanced cases.
- Weight management, in some cases, since extra load accelerates wear on the foot.
Conservative treatment helps many adults manage flat foot symptoms successfully, sometimes for years. Orthotics in particular can offload a stressed tendon and reduce pain enough for normal daily life.
Orthotics may not be enough when:
- Pain continues despite consistent use of well-fitted orthotics and supportive shoes.
- The arch has collapsed significantly, and the foot is becoming rigid.
- You can no longer rise onto your toes on the affected side.
- Pain has shifted to the outside of the ankle, suggesting bones are now hitting each other where the arch has fallen.
- Arthritis is developing in the midfoot or hindfoot joints.
- Daily walking, work, and activity are limited by foot and ankle symptoms.
When these signs appear, it is worth a focused evaluation rather than continuing to layer more supports onto a foot that is changing underneath them.
Surgical Correction Considerations
Flat foot correction surgery is not a single procedure. It is a category of procedures chosen to match the specific problem in each foot. The Mayo Clinic notes that surgical options for adult acquired flatfoot are tailored to the cause, the severity of the deformity, and whether the foot is still flexible or has become rigid.
| Procedure Type | What It Does | Typical Use |
|---|---|---|
| Tendon repair or transfer | Repairs the posterior tibial tendon or transfers another tendon to support the arch | Earlier-stage adult flat foot with a still-flexible foot |
| Osteotomy (bone realignment) | Reshapes one or more bones to restore alignment | Flexible flat foot with significant deformity |
| Joint fusion | Fuses one or more arthritic joints in the hindfoot or midfoot | Rigid flat foot or arthritis in midfoot or hindfoot joints |
| Combined procedures | Mixes tendon work, osteotomies, and selective fusions | Many real-world adult flat foot cases |
Flat foot correction surgery is a significant procedure with a recovery measured in months, not weeks. Most patients spend 6 weeks non-weight-bearing or in a protective boot, followed by a gradual return to weight bearing and physical therapy. The goal is a more stable, less painful foot that can support daily activity, not a perfectly arched foot.
What to Discuss Before Surgery
A useful conversation before flat foot surgery includes:
- What is causing the flat foot in your case
- Whether your foot is still flexible or has become rigid
- What specific procedure or combination of procedures is being considered
- How long the recovery will take and what restrictions you will have
- What activity goals are realistic afterward
- What happens if you do nothing or continue conservative care only
Dr. Parentis walks through these conversations with patients so the decision is informed and matched to each person's life.

Talk With Buffalo Orthopedics About Adult Flat Foot
If support alone is no longer keeping your foot comfortable, the next step is a focused evaluation. Catching adult flat foot earlier in its course gives you more options and better long-term outcomes than waiting until the foot has become rigid and painful.
To talk through your symptoms and your options, call Buffalo Orthopedics in Williamsville or Orchard Park. Dr. Parentis will examine your foot, review imaging, and outline a plan that may include orthotics, physical therapy, bracing, or flat foot correction surgery when appropriate.
Frequently Asked Questions
Where can I find flat foot treatment near me in Buffalo, NY?
Buffalo Orthopedics offers adult flat foot evaluation and treatment at its Williamsville and Orchard Park offices. Dr. Parentis brings 25 years of orthopedic expertise to each evaluation and works through nonsurgical care before considering flat foot correction surgery.
Are flat feet always painful?
No. Many adults have flat feet their entire life without symptoms. Pain is more likely when flat foot is acquired in adulthood, when the arch is dropping due to tendon or joint problems, or when the foot becomes rigid over time.
How do I know if my orthotics are working?
If orthotics meaningfully reduce your pain, allow you to be on your feet longer, and slow the progression of symptoms, they are doing their job. If you continue to have significant pain or notice the arch dropping further despite consistent use, an orthopedic evaluation is reasonable. However, orthotics will not help adult-acquired flatfoot deformity if it involves injury to the posterior tibial tendon
How long is the recovery from flat foot correction surgery?
Recovery varies based on the procedure. Most patients spend 6weeks non-weight-bearing or in a protective boot, followed by 2 months of gradual return to weight bearing and physical therapy. Dr. Parentis provides a specific timeline based on the procedure you have.
Can flat foot come back after surgery?
A well-planned flat foot correction is designed to be durable, but long-term outcomes depend on the procedure performed, the underlying tissue quality, weight, activity, and adherence to postoperative care. Realistic expectations and good follow-up support the best long-term results.
