New Guidelines for Preventing Periprosthetic Joint Infections
The recent updates to the Clinical Practice Guideline (CPG) for preventing Total Hip and Knee Arthroplasty Periprosthetic Joint Infection (PJI) due to dental procedures emphasize the importance of evidence-based practices. The American Academy of Orthopaedic Surgeons (AAOS) has published this updated guideline, replacing the previous 2012 version. The focus is on ensuring patient safety, especially for those who have undergone total joint arthroplasties (TJA) and may need dental work.
Understanding the Risk of Infections
Dental procedures pose a potential risk as they may allow bacteria to enter the bloodstream and settle onto implant surfaces, leading to PJI. According to Dr. Yale Fillingham, a co-chair of the AAOS guideline development team, "PJI can be a severe complication post-surgery, and we need to take all scientifically supported measures to reduce these risks. Considering that many TJA patients undergo dental cleanings multiple times a year, the relevance of this guideline extends to a vast group of individuals."
Statistical Insights on TJA
Globally, Total Hip Arthroplasties (THA) and Total Knee Arthroplasties (TKA) rank among the most commonly performed surgeries. In the U.S. alone, over one million THA and TKA procedures are conducted annually, with projections indicating staggering growth rates of 659% and 469% by 2060, respectively. It's vital to highlight that patients experiencing PJI may face up to a 250% increase in mortality risk compared to those without such infections.
Guidelines for Antibiotic Use
The updated CPG provides concise recommendations for orthopaedic surgeons and dentists regarding the use of antibiotics in different contexts related to dental work. The workgroup included evidence suggesting that routine systemic prophylactic antibiotics before dental procedures for patients with hip or knee replacements may not necessarily lower the risk of developing a subsequent PJI. Dr. Charles Hannon, another co-chair of the guideline team, emphasized that careful evaluation of the data indicated no significant change in risk levels concerning antibiotic administration relative to dental procedures.
PJIs and Poor Oral Hygiene
A further recommendation from the guideline discusses screening patients who have undergone dental procedures before their joint replacements. While this may not significantly reduce the risk of subsequent PJIs, it is prudent to inform patients of the potential risks associated with inadequate oral hygiene.
Resource Development for Healthcare Providers
To aid in understanding when to execute dental procedures relative to TJA, the workgroup has developed a reference tool that includes suggested timing intervals. This tool aims to clarify when it is appropriate to delay dental work after TJA and vice versa.
Effectiveness of the At-a-Glance Tool
Highlights of this reference guide include recommendations for the safe execution of noninvasive dental procedures right up until the day before elective TJA. However, more invasive procedures, like dental extractions, must occur at least three weeks before surgery to ensure sufficient healing time. Furthermore, dentists are advised to defer most dental work for three months following TJA to minimize infection risks.
The Development of the Updated CPG
This guideline was a collaborative effort between the AAOS, the American Association of Hip and Knee Surgeons, and other relevant organizations in the field of musculoskeletal health. The aim was to create a supportive framework for healthcare professionals, ensuring they are equipped to handle potential PJI cases pertinent to TJA.
Important to Note
CPGs are designed to serve as helpful references and do not represent strict protocols. They guide treatment and diagnosis based on the clinician’s independent judgment and the specific needs of individual patients. Therefore, patient care should always be tailored to their unique situations, especially concerning risks and benefits when making decisions.

Frequently Asked Questions
What is the purpose of the updated guideline?
The guideline aims to provide evidence-based recommendations to prevent PJIs in patients undergoing dental procedures post joint replacement surgery.
Who developed the new guidelines?
The updated guidelines were collaboratively developed by the AAOS and the American Association of Hip and Knee Surgeons, with input from various health organizations.
How often are THA and TKA performed in the U.S.?
Over one million of these surgical procedures are performed each year in the United States.
What are the safety recommendations for dental procedures?
Noninvasive dental procedures can be safely performed up until the day before elective surgery, while invasive procedures should occur at least three weeks prior to surgery.
Are antibiotics necessary before dental procedures?
The updated guideline indicates that routine antibiotic use prior to dental procedures may not significantly lower infection risks for individuals with hip or knee replacements.
