Sequential bilateral total ankle replacements: No difference in patient-reported outcomes between the first and second ankle

Abstract

Background: Total ankle replacement is an established treatment for end-stage arthritis. However, there is little data examining outcomes in sequential bilateral replacements. This study aimed to compare outcomes between first and second ankles in sequential replacement.

Methods: Patients were retrospectively contacted to complete a follow-up questionnaire including the Manchester-Oxford Foot Questionnaire (MOXFQ), EQ-5D-3 L, and a question assessing satisfaction. Electronic records identified demographics, procedural details, and complications.

Results: Twenty patients underwent sequential bilateral ankle replacement over the study period. At a mean follow-up of four years, 18 patients completed the follow-up questionnaire. There was no statistically significant difference between first and second ankles in terms of MOXFQ score, EQ-5D-3 L or satisfaction. Eleven complications were noted.

Conclusions: We report excellent outcomes after sequential bilateral ankle replacement with no difference in outcomes between first and second ankles. These results can be used to counsel patients in the future and manage expectations.

Level of evidence: IV.
