When to See a Podiatrist
Painful flat feet in adults can signal posterior tibial tendon dysfunction — a progressive condition that needs early intervention to avoid surgery. Balance Foot & Ankle evaluates adult flatfoot with weight-bearing imaging and custom orthotic prescriptions. Catching PTTD at stage 1-2 makes the difference between a brace and a reconstruction.

Differential Diagnosis: What Else Could It Be?
Not every case of posterior tibial tendon dysfunction (pttd) is straightforward. In our clinic we routinely rule out three look-alike conditions before confirming the diagnosis. If your symptoms don’t match the classic presentation, one of these may explain the pain — which is why physical exam matters more than self-diagnosis.
| Condition | How It Differs |
|---|---|
| Congenital flat foot | Lifelong, usually bilateral, no pain, normal single-leg heel-rise test. |
| Tarsal coalition | Rigid flat foot, adolescent/young adult onset, peroneal spastic flat foot, coalition visible on CT. |
| Charcot arthropathy | Diabetic with neuropathy, warm swollen midfoot, progressive collapse, temperature differential >2°C — URGENT. |
Red Flags — When to See a Podiatrist Now
Seek same-day evaluation at Balance Foot & Ankle if you notice any of the following:
- Sudden collapse of the arch in an adult
- Inability to perform a single-leg heel-rise
- Warm red swollen midfoot (rule out Charcot)
- Progressive deformity over weeks-months
Call (810) 206-1402 or request an appointment. Our Howell and Bloomfield Hills offices reserve same-day slots for urgent foot and ankle issues.
In Our Clinic: What We See
Clinical perspective from Dr. Tom Biernacki, DPM — Balance Foot & Ankle, Howell & Bloomfield Hills, MI:
In our clinic, adult acquired flatfoot from PTTD typically presents in women over 40, often with recent weight gain or a period of increased standing. They describe medial ankle pain and progressive “collapse” of the arch on one side. The gold-standard exam finding is an inability to perform a single-leg heel-rise on the affected side — the tendon can no longer invert the heel into a rigid lever. Early PTTD is staged and treated with custom orthoses and bracing, but progressive disease (Stage III-IV) typically requires surgical reconstruction to prevent rigid deformity.
