Introduction: There is a risk readmissions and complications following ankle replacements. Despite the increase in the numbers performed, there is limited evidence on the number of these complications. The aim of this cohort study was to determine the 30 day and 90 day readmission rates following total ankle replacement. Secondary aims were to determine the incidence of pulmonary embolism, surgical procedures and the risk factors for readmission.
Methods: A data linkage study combined National Joint Registry (NJR) Data and NHS Digital data. 30 day and 90 day readmissions were recorded. Multivaraible logistic regression was performed to analyse potential risk factors for failures for readmissions.
Results: A total of 5562 underwent an ankle replacement between between 1st April 2010 and 31st December 2018. The 30 day readmission rate was 3.2%and the 90 day readmission rate was 7.6%. The 30 day re-operation rate was 0.4% and 90 day re-operation rate was 1.13%. The incidence of pulmonary embolism was at 0.13% at 90 days.
Conclusion: There is a 3.2% 30 day readmission rate following total ankle replacement. The risk of medical complications including pulmonary embolism is low. This study demonstrates the safety of total ankle replacements.
