Abstract
There is great debate around how to treat patients with periprosthetic joint infections and there are different techniques utilised throughout the world with large regional differences. In the situation where implants are well fixed there is a potential advantage to retain ingrown implants in which removal would result in severe bone damage. However, there are multiple variables on both the patient side and the surgeon side which can influence the likelihood of success with this approach. In some patients, staged revision of large and well-fixed components will result in bone damage and compromised function, but the two-stage techniques may have great success at long term infection free survivorship. The literature suggests that selective implant retention and joint débridement may be an alternative for those patients who have complex well-fixed components, are not immunocompromised, have not developed sinus formation, and who have less virulent organisms on aspiration. Implant retention techniques should be approached with caution when patients have chronic illness such as diabetes or rheumatoid disease, use immunosuppressive medications, have a negative aspirate for microorganisms, or show any signs of loosening on radiographs or during intra-operative assessment. Like many aspects of patient care, proper patient selection and meticulous surgical techniques are important components to increasing success in these difficult clinical scenarios. This talk will focus on the data currently available in the literature to help participants gain a better understanding of how to individualise treatments for patients with periprosthetic infections.
