Prosthetic joint infections are an uncommon complication of joint replacement surgery, but are associated with significant morbidity and costs when they do occur. Gram-positive cocci, in particular Staphylococcus aureus and Staphylococcus epidermidis, are the most commonly recovered microorganisms (>= 50% of all isolates). About 60% of prosthetic joint infections probably occur by direct contamination during the operative procedure. Certain systemic conditions in the patients, as well as foreign material, have been identified as risk factors for prosthetic joint infection. The clinical diagnosis is only certain when there are sinus tracts that reach the prosthesis or purulent secretion is obtained from joint aspiration or during open surgery. The treatment of an infected joint prosthesis must be individualised, but it generally involves both systemic antibiotics and surgical intervention. Exchange arthroplasty in one or two stages continues to be the standard approach to management. Prosthesis retention, in conjunction with debridement and prolonged (for at least 3 months) oral antibiotic therapy, can be an alternative for early postoperative or late acute haematogenous infections, when the duration of symptoms is less than 1 month, the implant is stable, and the pathogen is relatively avirulent and sensitive to an orally well absorbed antibiotic. Good results have been achieved under these conditions in staphylococcal infections with rifampin associated with quinolones and other antibiotics, e.g., cotrimoxazole, fusidic acid, and linezolid.
