As shown in this figure, the number of cases of prosthetic joint infection is increasing.  Patient-related risk factors for prosthetic joint infection include prior revision arthroplasty or prior same site prosthetic joint infection, tobacco abuse, obesity, rheumatoid arthritis, malignancy, immunosuppression, and diabetes.  Surgical risk factors include simultaneous bilateral arthroplasty, operative time greater than 2.5 hours, and allogeneic blood transfusion.  Post-operative risk factors include wound-healing complications (such as superficial infection, hematoma, delayed healing, wound necrosis, dehiscence), atrial fibrillation, myocardial infarction, urinary tract infection, prolonged hospital stay and, Staphylococcus aureus bacteremia.  The cost of treating prosthetic hip infection is estimated at $59,677 per episode.
