Background: The ability to return to physical activity is an important indicator of surgical success for end-stage ankle arthritis. There is paucity of literature comparing outcomes between surgical procedures. This study aimed to compare outcomes for physical activity and return to function between total ankle replacement (TAR) and ankle arthrodesis (AA) at 1-year follow-up.
Methods: This was a single-centre prospective follow-up study. Patients who underwent TAR (n=33) or AA (n=25) between 2022-2023 completed questionnaires on FAOS scores (Pain, Symptoms, ADL and QOL domains), International Physical Activity Questionnaire (IPAQ), satisfaction scores and return to work/driving. IPAQ physical activities were compared across domains of work, transportation, domestic and leisure activities.
Results: AA patients were younger (59.1 vs. 65.8). The AA group had better average FAOS scores for pain, symptoms, ADL, and QOL compared to TAR (51.2 vs. 29.2; 40.6 vs. 67.8, 46.8 vs. 66.4, 31.3 vs. 48.3) (p=0.526), but the TAR group reported higher overall satisfaction (77% vs. 66.6%).Earliest return to work was reported at 2 weeks (TAR) vs. 3 weeks (AA) group and driving at 3 weeks (TAR) vs. 4 weeks (AA). More TAR patients returned to vigorous (25%) and moderate (17.6%) physical activity versus AA (0% and 0%). For transport, 4 AA patients vs. 12 TAR patients returned to this activity. AA patients travelled 30 minutes to 2 hours per week, while TAR patients travelled 30 minutes to 5 hours. For household activities, 15.7% of TAR patients reported vigorous activity versus 0% in AA. AA patients spent less time on average leisure walking (1.25 hrs vs. 2 hrs), and more time sitting per day (9.2 hrs vs. 5.9 hrs).
Conclusion: The TAR group demonstrated earlier return to work, driving, and higher levels of physical activity compared to AA patients at 1-year follow-up, despite the AA group having better FAOS scores.
