Perioperative and Modifiable Risk Factors for Periprosthetic Joint Infections (PJI) and Recommended Guidelines.

PURPOSE OF REVIEW: Periprosthetic joint infection (PJI) remains a complication that is associated with high morbidity as well as high healthcare expenses. The purpose of this review is to examine patient and perioperative modifiable risk factors that can be altered to help improve rates of PJI.

RECENT FINDINGS: Evidence-based review of literature shows that improved control of post-operative glycemia, appropriate management of obesity, malnutrition, metabolic syndrome, preoperative anemia, and smoking cessation can help minimize risk of PJI. Additionally, use of Staphylococcus aureus screening, preoperative evaluation of vitamin D levels, screening for urinary tract infection, and examination of dental hygiene can help with improving rates of PJI; similarly, appropriate management of perioperative variables such as limiting operating room traffic, appropriate timing, and selection of prophylactic antibiotics and surgical site preparation can help to decrease rates of PJI. In summary, PJI is a morbid complication of total joint arthroplasty. Surgeons should be vigilant of modifiable risk factors that can be improved upon to help minimize the risk of PJI.
