Short summary
This single-center retrospective study focused on the utility of modular megaprostheses in patients with chronic hip or knee periprosthetic joint infections. Among the 61 included patients, 37.7 % experienced any type of failure, with infection recurrence being the most common reason. While infection control was acceptable, the rates of any-type failure were high. Moreover, patients classified as McPherson host grade C, representing compromised hosts, are at greater risk of experiencing failure.
