Patient-perceived outcomes after subtalar arthroereisis with bioabsorbable implants for flexible flatfoot in growing age: a 4-year follow-up study.

Abstract

Results of subtalar arthroereisis in flexible flatfoot have been mainly reported in the literature using clinical or radiographical findings. However, the aim of this study is to evaluate the patient-perceived quality of life using self-reported questionnaires after subtalar arthroereisis using a bioabsorbable implant. Italian modified FFI and the SEFAS scores were submitted to a consecutive series of 173 patients who underwent surgical treatment for flatfoot deformity using a bioabsorbable endo-orthotic implant. Postoperative complication rates were assessed. Time needed to resume normal sports activities was recorded. Mean population age was 11.2 years with slight variability between males and females. At a mean follow-up of 4 years, arthroereisis with bioabsorbable implants showed excellent results for the perception of the quality of life with an average result for FFI score of 4.5 and an average SEFAS score of 47.19. Time needed to resume sport activities was 4.7 months ± 0.2 with almost no difference between the groups. Four patients needed a second procedure for implant removal. Arthroereisis using a bioabsorbable implant offers good results in terms of satisfaction and quality of life with a negligible rate of failures and patient complaints based on self-reported questionnaires. The patient reported high degrees of satisfaction, and their quality of life was not compromised at all by the procedure.
