Abstract
BACKGROUND

Periprosthetic joint infections (PJIs) are frequently caused by coagulase-negative Staphylococci (CoNS), which is known to be a hard-to-treat microorganism. Antibiotic resistance among causative pathogens of PJI is increasing. Two-stage revision is the favoured treatment for chronic CoNS infection of a hip or knee prosthesis. We hypothesised that the infection eradication rate of our treatment protocol for two-stage revision surgery for CoNS PJI of the hip and knee would be comparable to eradication rates described in the literature.

AIM

To evaluate the infection eradication rate of two-stage revision arthroplasty for PJI caused by CoNS.

METHODS

All patients treated with two-stage revision of a hip or knee prosthesis were retrospectively included. Patients with CoNS infection were included in the study, including polymicrobial cases. Primary outcome was infection eradication at final follow-up.

RESULTS

Forty-four patients were included in the study. Twenty-nine patients were treated for PJI of the hip and fifteen for PJI of the knee. At final follow-up after a mean of 37 mo, recurrent or persistent infection was present in eleven patients.

CONCLUSION

PJI with CoNS can be a difficult to treat infection due to increasing antibiotic resistance. Infection eradication rate of 70%-80% may be achieved.

Core tip: Periprosthetic joint infections of the hip and knee caused by coagulase-negative Staphylococci can be difficult to treat. We retrospectively reviewed all patients treated with two-stage revision arthroplasty for such an infection in our hospital between 2003 and 2016. We treated 44 patients with coagulase-negative Staphylococci infection of the hip or knee with a two-stage revision using an antibiotic-loaded spacer. At final follow-up, infection was eradicated in 33 of these patients.
