[Indications for antibiotic prophylaxis in patients with a prosthetic joint].

Under certain circumstances, patients with a prosthetic joint and a focal infection elsewhere in the body may be at risk of developing bacterial infection of the prosthesis. Patients and physicians should actively prevent infections that can spread systemically. Routine antibiotic prophylaxis is not recommended for all patients with a prosthetic joint and suspected bacteraemia. Antibiotic prophylaxis is warranted in three groups of patients with a prosthetic joint who must undergo an invasive procedure that could cause bacteraemia: patients with a predisposing immunocompromising systemic condition or those receiving immunosuppressive therapy, patients with a dermatological infection, and patients with an obvious focal infection, e.g., urosepsis. If the patient is already receiving antibiotics for the infection, additional prophylaxis is usually unnecessary. For patients undergoing dental procedures who require antibiotic prophylaxis, amoxicillin-clavulanic acid or clindamycin are preferred.
