Progressively collapsing flat feet (PCFD), formerly known as adult-acquired flatfoot, is a complex condition where the arch of the foot gradually flattens, leading to deformities and pain. It is often linked to dysfunction of the posterior tibial tendon (PTT), which supports the arch. Over time, this condition can cause significant instability and difficulty walking.

Causes & Risk Factors

• Posterior tibial tendon dysfunction (PTTD), leading to loss of arch support

• Ligament damage, including the spring ligament

• Obesity or increased body weight

• Inflammatory conditions like rheumatoid arthritis or psoriasis

• Foot injuries or repetitive strain

• Genetic predisposition to flatfoot structure

Symptoms

• Gradual flattening of the arch

• Pain and swelling on the inside or outside of the foot and ankle

• Difficulty standing on toes

• Weakness in the foot muscles

• Progressive deformity affecting foot function

Treatment Options

• Orthotics & Braces: Custom orthotics can help support the arch and reduce strain.

• Footwear Adjustments: Supportive shoes with arch support.

• Anti-inflammatory Medications: To reduce pain and swelling.

• Surgery: In severe cases, procedures may involve tendon repair, ligament reconstruction, or bone realignment.

Prevention & Management

• Maintain a healthy weight to reduce stress on the foot.

• Wear supportive footwear with proper arch support.

• Avoid prolonged standing or walking on hard surfaces without proper support.
