Abstract
There is no standard treatment for infected joint replacements. The surgical options are varied and treatment choices may pose problems in relation to both efficacy and cost effectiveness. Surgical debridement combined with antibiotic therapy is an appealing option for surgeons and patients as it can lead to eradication of the infection with implant retention and good functional outcome. It avoids major revision surgery which can result in significant morbidity and mortality in an elderly group of patients.
The author reviewed 73 patients with hip and knee periprosthetic infections and the data was analyzed in terms of outcome of primary treatment and final outcome, including bacteriology and prosthesis retention. Out of the 73 patients (53 hips and 20 knees), the majority (69%) were managed by primary surgical debridement followed by antibiotics and about one third (34%) lost their implants as a result of the infection. Retention of implants was higher in acute infections (85–100%) as opposed to late infections (20–50%). The microbiological analysis showed that Staphylococcus and Streptococcus caused the majority (76%) of infections. In this series, patients with an infected joint replacement had roughly the same probability (30%) of retaining the original prosthesis, undergoing a successful revision, or having no implants in situ at the end of treatment.
