Periprosthetic joint infection (PJI) is regarded as a critical factor contributing to the failure of primary and revision total joint arthroplasty (TJA). With the increasing prevalence of TJA, a significant increase in the incidence of PJI is expected. The escalating number of cases, along with the significant economic strain imposed on healthcare systems, place emphasis on the pressing need for development of effective strategies for prevention. PJI not only affects patient outcomes but also increases mortality rates, thus its prevention is a matter of vital importance. The longer-term survival rates for PJI after total hip and knee arthroplasty correspond with or are lower than those for prevalent cancers in older adults while exceeding those for other types of cancers. Because of the multifaceted nature of infection risk, a collaborative effort among healthcare professionals is essential to implementing diverse strategies for prevention. Rigorous validation of the efficacy of emerging novel preventive techniques will be required. The combined application of these strategies can minimize the risk of infection, thus their comprehensive adoption is important. Collectively, the risk of PJI could be substantially minimized by application of a multifaceted approach implementing these strategies, leading to improvement of patient outcomes and a reduced economic burden.

Periprosthetic joint infection (PJI) is the most significant factor contributing to failure of primary and revision total joint arthroplasty (TJA)1). The number of TJAs is increasing daily. It is predicted that by 2060 in the United States, the volume of patients aged ≥65 years undergoing primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) will increase by 559%2). With the increasing number of TJA cases, the incidence of PJI will also increase. With estimated annual hospital spending expected to reach \$1.85 billion (approximately \$6 per person in the US) by 2030, PJI of the hip and knee still imposes a significant financial burden on the US healthcare system3).
The consequences of PJI can be severe. Significantly higher mortality has been reported for patients undergoing surgery for treatment of PJI compared to patients undergoing aseptic revision arthroplasty4). A study conducted by Berend et al.5) reported that the mortality rate within 90 days following a two-stage exchange surgery was 4%, while an extra 7% of patients died prior to undergoing the second stage procedure. The 5-year overall survival rates for PJI following THA and TKA are comparable to or lower than those for two of the most commonly occurring cancers in older adults in the US (prostate and breast), higher than those for other cancers6).
Some organizations have discussed the preventive practices approved by the latest clinical practice guidelines for surgical site infection (SSI) and prevention of PJI; for example, Centers for Disease Control and Prevention, International Consensus Meeting on Musculoskeletal Infection, and American Academy of Orthopedic Surgeons5,7,8). The purpose of the current study was to review and summarize the 10-step approach for prevention of PJI.
Prior to undergoing joint replacement surgery, collection of detailed information regarding the patient’s medical history and overall health is essential to ensure appropriate preoperative assessment and care. Several factors can play a critical role in minimizing the risk of PJI, including postoperative glycemia control, management of immunosuppression, appropriate management of obesity, malnutrition, metabolic syndrome, preoperative anemia, and smoking cessation9). Smoking, including its primary component nicotine, has been linked to microvascular constriction and reduced supply of oxygen to tissues10). In a comprehensive national database study, Duchman et al.11) reported an elevated risk of SSI among both current and former smokers, and the rate of wound complications was higher for current smokers compared to former smokers. In addition, preoperative evaluation of vitamin D levels, screening for urinary tract infection, and dental hygiene examinations can contribute to reducing the rates of PJI. Vitamin D deficiency is more common in the US population and studies have demonstrated that low levels of vitamin D can increase the risk of PJI. Preoperative optimization of serum vitamin D should be considered. A higher risk of infection has been reported for patients with uncontrolled diabetes12). Hemoglobin A1c (HbA1c) is used for long-term glycemic control and HbA1c should be less than seven12). In addition, recent studies have demonstrated the accuracy of fructosamine, a glycemic marker, in prediction of adverse outcomes following THA13).
SSI, a commonly encountered complication following surgery, is characterized by infection at the incision site. It imposes a significant burden on both patients and healthcare systems, contributing to extended hospital stays, increased utilization of healthcare resources, and increased healthcare costs. Use of antiseptic solutions such as chlorhexidine or povidone-iodine is preferred in the effort to avoid SSI. Although both solutions are effective in reducing occurrence of surgical infections, compared with aqueous iodine in any type of surgery, 2.0%-2.5% chlorhexidine in alcohol showed the highest efficacy. Guidelines on prevention of SSIs published by the World Health Organization (WHO), the UK National Institute for Health and Care Excellence (NICE), and the US Centers for Disease Control and Prevention (CDC) have provided contrasting recommendations regarding surgical skin preparation. NICE and WHO support the use of chlorhexidine in alcohol, while the CDC has suggested the use of any type of alcohol-based solution. A study by Jalalzadeh et al.14) recommended the use of 2.0%-2.5% chlorhexidine in alcohol as an effective preoperative skin preparation for any type of surgery. If this concentration is not available, alternatives such as 0.5% or 4.0% chlorhexidine in alcohol may be used. Hair removal, another aspect of surgical site preparation, can potentially increase the occurrence of SSIs, thus hair removal should be minimized when necessary9,12,14,15).
In addition, nasal colonization by
Despite limited supporting evidence, CDC guidelines recommend administration of a single preoperative dose for patients undergoing TJA16). In addition, according to a study conducted by Christensen et al.17), no difference in occurrence of acute PJI, superficial infections, reoperations. or overall complications was observed between the 24-hour antibiotic prophylaxis group and the single-dose antibiotic prophylaxis group. In contrast, compared with patients receiving single-dose antibiotic prophylaxis, patients receiving 24-hour antibiotic prophylaxis had significantly longer lengths of stay, longer operative time, and elevated body mass index, and were more likely to have undergone a bilateral procedure. Regarding antibiotic use, intravenous administration of the first generation of cephalosporin within 30 to 60 minutes before incision as a single and weight-adjusted dose is recommended18,19). Prior to the guideline updates, an allergic reaction to penicillin involving skin lesions or local swelling was categorized as a severe allergy, for which clindamycin or vancomycin was recommended as second-line prophylaxis. However, the updated guidelines have excluded skin lesions and local swelling, thereby redefining what constitutes a severe allergy20). In addition, considering the high rates of Staphylococcal resistance to clindamycin, the updated guidelines now recommend streamlining the use of vancomycin as the sole option for second-line prophylaxis21).
Failure during any step in the reprocessing of surgical instruments is associated with a higher risk of microorganism transmission. Gloving is crucial for safeguarding both the surgeon and the patient against blood-borne viruses and preventing contamination of the surgical wound by skin flora22). In addition, wound infections pose a challenge for physicians, and selection of suture material can play a crucial role in preventing infection. However, objective data guiding selection of materials are limited. Sutures, which act as foreign bodies, harbor bacteria, increasing the risk of infection. While they can promote tissue healing and limit contamination, the choice of suture material can influence resistance to infection23).
Operative time is a significant factor affecting SSI. In general, longer surgical operation time can result in extended tissue exposure, increased fatigue, and technical errors among the surgical team, as well as reduced systemic defenses of the body24). One study demonstrated that the duration of surgery was a significant risk factor for development of SSIs. Employment of strategies to reduce the duration of surgical operations can be a practical approach to reducing the rate of SSIs25). A recent study26) also reported an association of procedure time with increased risk of SSI. Competence of support staff during performance of operations may affect procedure time and this can be improved. Preoperative planning can also be helpful in reducing the time spent on decision making during surgery and in predicting materials requirements27). This may include employment of strategies such as the adoption of novel technologies that may be helpful in the effort to enhance operative efficiency, utilization of specialized care teams, and preventing overwork or fatigue among operating staff. Administration of additional doses of antibiotics is a generally accepted approach, in cases when the duration of surgery is prolonged and blood loss is high28).
The detrimental effects of allogeneic blood transfusion, both in general and specifically regarding the outcomes of TJA, have been clearly delineated through conduct of extensive research. An association of allogeneic blood transfusion with increased overall mortality and heightened risk of subsequent SSI has been consistently demonstrated. With supporting evidence from several studies, in the bilateral group, an association of the duration of surgery with a significant increase in the incidence of receiving an allogeneic transfusion has been reported. Therefore, emphasis on reducing operation time is important in order to alleviate the need for allogeneic transfusions and their associated risks29,30). The results of one study showed significant correlations between transfusion risk and several factors, including advancing age, female gender, lower body weight, preexisting anemia, longer surgical duration, exclusive use of general anesthesia, American Society of Anesthesiologists class higher than II, and undergoing revision surgery31).
Use of venous thromboembolism prophylaxis agents following TJA has become routine. However, potential side effects including bleeding should be noted. The potential for bleeding associated with the use of these agents should be an important consideration32).
An association of increased airborne bacterial counts with traffic within the operating room (OR) has been noted. The act of opening doors, which can potentially increase air and wound contamination, can contribute to colonization of bacteria. Numerous studies have reported statistically significant correlations between the frequency of door openings and elevated airborne bacterial counts33-35). Studies directly addressing nursing personnel and for implementation of interventions supporting a reduction in OR traffic due to the request for information have been conducted. Low-cost interventions such as door signage explicitly prohibiting entry by nonessential traffic or personnel and use of retractable tape as a physical barrier for OR doors have resulted in significantly increased awareness and have been helpful in addressing concern regarding OR traffic. The impact of these simple yet effective measures can prove substantial in the effort to mitigate the issue36,37).
While chlorhexidine combined with alcohol is effective for preoperative skin preparation, use of povidone-iodine along with chlorhexidine for this purpose is still a common practice among many orthopedic surgeons38). The results of one study indicated that the shortest time to elimination of
Sterilization of implants and instruments during all steps of an operation is essential in preventing infection40). Several methods can be used for sterilization, including heat (steam), dry heat, radiation, ethylene oxide gas, vaporized hydrogen peroxide, and other sterilization methods (chlorine dioxide gas, vaporized peracetic acid, nitrogen dioxide, etc.)41). Based on the rates of microbiological contamination, changing gloves after draping, prior to handling implants, and whenever visible perforation is detected is recommended. Considering the correlation between the duration of surgery and increasing rates of microbiological contamination, changing gloves at least once per hour is advisable, unless there are other compelling reasons to do so42). Over time, increasing contamination can affect all types of implant materials. Taking simple precautions, such as covering the implant set, can reduce the risk of contamination43).
Wound healing is an important factor in prevention of PJI. Recently, use of innovative surgical bandages, such as hydro fiber absorbent dressings, as an effort to minimize medication requirements while promoting enhanced wound healing and preventing infiltration of external bacterial into the wound site has been increasingly recommended44,45). According to Lung et al.46), the efficacy of chlorhexidine gluconate is comparable to that of dilute betadine in preventing PJI, while also reducing the incidence of superficial drainage and wound complications that necessitate unplanned visits to the emergency department during the acute postoperative period. The suture should fulfill its intended purpose while minimizing adverse reactions as well as the risk of infection, ensuring sufficient duration of effectiveness and strength. However, a suture with greater strength or high tensile strength is not considered universally superior due to the required increase in suture thickness and the potential for unintended tissue constriction, which could potentially exacerbate the inflammatory response47).
Prevention of SSI and PJI is more important than diagnosis and treatment. The more PJIs that can be prevented, the greater the reduction of the economic and mental burden inflicted by PJI on the state and patients. Given the multifactorial nature of infection risk, mobilization of all healthcare professionals toward prevention through use of a variety of strategies is essential. In addition, with the continued introduction of novel preventive methods in this sphere, confirming the reliability of these strategies remains critical. Combined application of these individually important strategies can minimize the risk of infection.
