| Stage II (A) | Attenuated / partial tear | Flexible flatfoot with forefoot abduction; heel valgus <30% | Flexible | Positive (1–2 toes visible lateral) | AFO or UCBL orthotic; if failed: medial displacement calcaneal osteotomy + FDL transfer |
| Stage II (B) | Attenuated / partial tear | Flexible flatfoot with forefoot abduction >30%; significant heel valgus | Flexible | Positive (3+ toes visible lateral) | Calcaneal lengthening (Evans) + FDL transfer + medial column stabilization |
| Stage III | Incompetent / complete rupture | Rigid flatfoot; subtalar arthritis | Rigid — no correction on tiptoe | Marked positive | Subtalar arthrodesis ± talonavicular fusion (double) |
| Stage IV | Incompetent | Stage III + deltoid insufficiency; ankle valgus tilt | Rigid | Marked positive | Pantalar or tibiotalocalcaneal fusion; deltoid reconstruction |
| Surgical Procedure | Stage Indication | Mechanism | Recovery | Success Rate |
|---|---|---|---|---|
| FDL Tendon Transfer | Stage II (all) | Flexor digitorum longus transferred to navicular to replace PTT function | 6–8 weeks NWB; 4–6 months full activity | 90%+ for pain relief with concurrent bony procedure |
| Medial Displacement Calcaneal Osteotomy (MDCO) | Stage II-A | Shifts calcaneus medially to correct heel valgus; improves mechanical axis | 6–8 weeks NWB; 4–6 months | 85–90% |
| Lateral Column Lengthening (Evans Osteotomy) | Stage II-B with forefoot abduction | Bone graft opens lateral calcaneus; corrects abduction and arch | 8–10 weeks NWB; 4–6 months | 85–90% with FDL transfer |
| Subtalar Arthrodesis | Stage III | Fuses subtalar joint in corrected position; eliminates subtalar arthritis pain | 8–10 weeks NWB; 6 months full activity | 85–90% pain relief; gait alteration |
| Double Arthrodesis (ST + TN) | Stage III with TN arthritis | Fuses subtalar + talonavicular for more stable correction | 10–12 weeks NWB; 6–9 months | 80–85% |

Quick Answer:
Quick Answer: Adult flatfoot causes pain and progressive collapse of the arch. Dr. Biernacki treats flatfoot with custom orthotics, supportive footwear, and when conservative care fails, performs reconstructive surgery to restore arch height and eliminate pain.

Adult flatfoot develops when the arch collapses, causing the entire sole of the foot to contact the ground. This can result from posterior tibial tendon dysfunction, Charcot neuroarthropathy, or other conditions. Adult flatfoot causes pain, affects gait, and limits activities. At Balance Foot & Ankle, Dr. Tom Biernacki specializes in treating flatfoot with both conservative management and reconstructive surgery.
Understanding Adult Flatfoot
Adult flatfoot differs from pediatric flatfoot in that it involves actual deformity and structural changes. The arch collapses, the foot becomes unstable, and pain develops over the inner arch and outer foot. The condition often worsens over time if untreated, leading to arthritis and functional decline.
Conservative Treatment Options
Initial management includes custom orthotics with arch support to restore alignment, supportive footwear, activity modification, and physical therapy. Anti-inflammatory treatment and bracing can reduce pain and slow progression. Many patients improve significantly with conservative care.
Surgical Reconstruction
When conservative care fails, Dr. Biernacki performs reconstructive surgery to restore arch height. Procedures may include tibialis posterior tendon repair, lateral column lengthening, osteotomies, or arthrodesis depending on the severity and cause of flatfoot. Surgery restores normal foot mechanics and eliminates pain.
Recovery and Rehabilitation
Recovery from flatfoot surgery is gradual. Patients wear protective boots for 6-8 weeks, then progress to physical therapy and weight-bearing exercises. Return to normal activities typically occurs by 3-4 months. Dr. Biernacki’s close coordination with physical therapy ensures optimal outcomes.

✅ Pros / Benefits
- Conservative care effective for many
- Reconstructive surgery restores normal anatomy
- Prevents long-term arthritis
- Restores normal function and eliminates pain
❌ Cons / Risks
- Surgery requires significant recovery time
- Physical therapy essential for outcomes
- Some chronic changes may be irreversible
Dr. Tom Biernacki’s Recommendation
Adult flatfoot is progressive—it doesn’t get better on its own. But it’s very treatable. With proper orthotics early, many patients avoid surgery. For those who do need surgery, reconstructive procedures have excellent outcomes and get people back to normal function.

Frequently Asked Questions
Is my flatfoot from childhood going to get worse as an adult?
Pediatric flatfoot usually stays flexible and benign. Adult flatfoot, however, tends to worsen without treatment. If you develop pain or functional decline, see Dr. Biernacki for evaluation.
What causes adult flatfoot?
Common causes include posterior tibial tendon dysfunction, Charcot neuroarthropathy, ankle arthritis, and inflammatory arthropathies. Dr. Biernacki determines the cause to guide treatment.
How long can I delay flatfoot surgery?
If conservative care is working and pain is controlled, surgery can be delayed. However, progressive flatfoot with untreated pain often develops arthritis. Early intervention prevents complications.
What is the success rate of flatfoot reconstruction surgery?
Modern flatfoot reconstruction has good success rates for pain relief and functional restoration. Results depend on the severity, cause, and adherence to rehabilitation.
