Kinetics of functional recovery after foot and ankle surgery. Comparison of EFAS and SF36 scores

International audienceIntroduction: The EFAS score is a new recently validated European quality of life score for foot and ankle surgery, comprising 6 questions on activities of daily living (ADL) and 4 on sport. The aim of the present study was to assess the kinetics of functional recovery on the EFAS and SF36 scores, and to assess correlations between the two at 0 to 6 months then 6 months to 1 year in a population of foot and ankle surgery patients, globally and per pathology. Hypothesis: Hindfoot and ankle surgery requires at least 1 year's follow-up for assessment of recovery, whereas 6 months is sufficient to assess forefoot recovery. Material and methods: A multicenter prospective cohort study included all patients undergoing surgery for foot and ankle pathology between December 2015 and July 2016. Statistical analysis, global and per pathology, was performed preoperatively and at 6 months and 1 year. Results: In total, 98 patients were assessed at 1 year. In the global population, EFAS ADL score improved by 17.1 ± 22.1 points (hindfoot, 16.9 ± 24.6; forefoot, 19.7 ± 21.4) and global SF36 score by 8.7 ± 17.1 points (hindfoot, 10.2 ± 19.1; forefoot, 9.6 ± 15.9). Both scores progressed between 6 months and 1 year for hindfoot pathologies, whereas they remained constant after 6 months for the forefoot. The EFAS score showed weak correlation with SF36
