Adult acquired flatfoot is a progressive condition in which the arch of the foot gradually collapses, often driven by dysfunction of the posterior tibial tendon. Dr. Hanson evaluates and treats flatfoot deformity at all stages, from early tendon dysfunction through advanced collapse requiring reconstructive surgery.
Unlike the flexible flatfoot that many people are born with, adult acquired flatfoot develops over time, typically in middle-aged or older adults. The posterior tibial tendon, which runs along the inside of the ankle and supports the arch, progressively weakens, stretches, and can eventually tear. As the tendon fails, the arch collapses and the foot drifts outward.
The condition progresses through distinct stages, and treatment depends heavily on which stage has been reached. Early stages are primarily a tendon problem, while later stages involve fixed bony deformity of the hindfoot and midfoot. Identifying the stage correctly is essential to selecting the right treatment.
Early intervention significantly improves outcomes. When the tendon is intact but inflamed, conservative treatment can halt progression. More advanced deformity typically requires surgery to restore alignment.
Dr. Hanson has published peer-reviewed work on tendon transfers and their complications, giving him a particularly nuanced understanding of the reconstructive procedures used in flatfoot correction. He has treated flatfoot deformity at every stage, from early posterior tibial tendon dysfunction through complex hindfoot reconstructions.
Dr. Hanson will take time to understand your specific situation, review any prior imaging or records, and give you an honest assessment of all your options including non-surgical approaches.
