Background Although the rate of both superficial and deep infection in total ankle replacement (TAR) can reach up to 13% as reported in the literature, there is little information on the causative organisms, especially in laterally implanted prosthesis. This study aims to identify organisms causing infections to ultimately guide to better antibiotic prophylaxis. Methods Between September 2016 and April 2021, we retrospectively reviewed patients who had an infection after a lateral TAR. Cause of the infection, causative organisms, and implant survival were recorded. Results Out of 130 patients, 10 of 130 patients (7.6%) had a superficial infection whereas 3 of 130 patients (2.3%) had a deep infection. Staphylococcus and Pseudomonas species were found to be the most common. No significant difference was found between the type of plate used for fibula fixation regarding wound dehiscence. Conclusions Infection after lateral TAR is generally polymicrobial in nature with Staphylococcus and Pseudomonas species being the most common. Level of Evidence: Level IV Case Series
