Posterior Tibial Tendon Dysfunction (PTTD): Adult Flatfoot Explained | Michigan Podiatrist

Medically reviewed by Dr. Tom Biernacki, DPM · Board-Certified Podiatric Surgeon · Last reviewed: April 2026 · Editorial Policy

Quick Answer

Posterior Tibial Tendon Dysfunction (PTTD): Adult Flatfoot E relates to tendon injury — typically caused by overuse or sudden strain. Most patients improve in 6-12 weeks with conservative care. Same-week appointments in Howell + Bloomfield Twp: (810) 206-1402.

Quick Answer

Flat feet (pes planus) means the arch has collapsed, causing the ankle to roll inward. When flat feet cause plantar fasciitis, shin splints, or knee pain, custom orthotics combined with supportive footwear resolve most cases. Asymptomatic flat feet usually need no treatment.

Differential Diagnosis: What Else Could It Be?

Several conditions share symptoms with Flat Feet (Pes Planus) and are commonly misdiagnosed in the first office visit. Considering these alternatives is part of every Balance Foot & Ankle exam:

  • Posterior tibial tendon dysfunction (PTTD). Acquired adult flatfoot with single-leg heel-rise weakness.
  • Tarsal coalition. Rigid flatfoot in an adolescent — bone bridge between hindfoot bones.
  • Charcot foot (diabetic). Sudden warm, swollen, collapsing midfoot in a diabetic — urgent off-loading.

If your symptoms don’t fit the textbook pattern, ask your podiatrist which differentials they ruled out — that conversation often shortcuts months of trial-and-error treatment.

In Our Clinic

In our clinic, the flat-footed patient who actually needs intervention is the one whose arch is collapsing progressively in adulthood — not the person who was born flat-footed and has been running 5Ks pain-free for 20 years. We evaluate for posterior tibial tendon dysfunction (PTTD) with single-heel-rise testing, check for the “too many toes” sign from behind, and get weight-bearing X-rays. Early PTTD responds well to a custom orthotic with a medial heel skive + short course of boot immobilization. Stage 2+ PTTD is a different conversation — we discuss tendon transfers and calcaneal osteotomy candidates.

Most Common Mistake We See

The most common mistake we see is: Buying motion-control shoes without a gait assessment. Fix: get a pressure-plate analysis or wet-foot test first to confirm overpronation and arch height.

Warning Signs That Need Same-Day Care

Seek immediate evaluation at Balance Foot & Ankle if you experience any of the following:

  • Rapid collapse of an arch on one foot (possible PTT rupture)
  • Walking becoming impossible
  • Redness or warmth along the inner arch
  • Diabetes plus progressive arch collapse
