Pediatric flexible flatfoot is sometimes asymptomatic but it can also cause physical impairment, pain, and difficulty walking. We evaluate the radiographic effectiveness of intervention of subtalar arthroereisis with endorthesis for pediatric flexible flatfoot with final follow-up at skeletal maturity.

| AOFAS | American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale. It is a measure of ankle and hidfoot function. It comprises nine questions and covers three categories: pain (40 points), function (50 points) and alignment (10 points). These are all summed together for a maximun score of 100 points (best otucome) and a minimum score of 0 (worst outcome). It includes a mixture of questions that are both subjective and objective in nature. |

We retrospectively review 60 consecutive patients who underwent surgical treatment with subtalar arthroereisis for pediatric flexible flatfoot at the authors' institution from January 2011 to March 2015.
