Purpose The primary aim of this study was to define the rate of infection following revision of fixation for aseptic failure. The secondary aims were to identify factors associated with an infection following revision and patient morbidity following deep infection. Methods A retrospective study was undertaken to identify patients who underwent aseptic revision surgery during a 3-year period (2017–2019). Regression analysis was used to identify independent factors associated with SSI. Results Eighty-six patients were identified that met the inclusion criteria, with a mean age of 53 (range 14–95) years and 48 (55.8%) were female. There were 15 (17%) patients with an SSI post revision surgery ( n  = 15/86). Ten percent ( n  = 9) of all revisions acquired a ‘deep infection’, which carried a high morbidity with a total of 23 operations, including initial revision, being undertaken for these patients as salvage procedures and three progressed to an amputation. Alcohol excess (odds ratio (OR) 1.61, 95% CI 1.01–6.36, p  = 0.046) and chronic obstructive pulmonary disease (OR 11.1, 95% CI 1.00–133.3, p  = 0.050) were independently associated with an increased risk of SSI. Conclusion Aseptic revision surgery had a high rate of SSI (17%) and deep infection (10%). All deep infections occurred in the lower limb with the majority of these seen in ankle fractures. Alcohol excess and COPD were independent risk factors associated with an SSI and patients with a history of these should be counselled accordingly.
