Determinants of functional outcome following ankle fracture.
Objectives: To assess the patient and injury characteristics that impact functional outcomes after ankle fracture.
Design: Retrospective study.
Setting: Urban level I trauma center.
Patients/Participants: One thousand patients underwent fixation of ankle fracture (AO/OTA 44) between 2006 and 2015. Four hundred sixteen completed functional outcome surveys by telephone or mail at a mean of 5.9 years after injury.
Intervention: Open reduction internal fixation.
Main outcome measure: Foot Function Index (FFI) and Short Musculoskeletal Function Assessment (SMFA).
Results: Mean age was 46.7 years, with 46.2% male. Higher (worse) FFI scores were seen in tobacco users (38.9 vs 30.1), recreational drug users (45.9 vs 32.7), and the morbidly obese (52.0 vs 30.6), all
Conclusion: Patient characteristics, not under surgeon-control, such as female sex, obesity, and substance use, appear to contribute to patient-reported functional outcome scores more than injury characteristics.
Level of Evidence: Level 3, prognostic.
