Abstract:
Periprosthetic joint infection (PJI) is a potentially catastrophic complication of total joint arthroplasty of the lower extremity. PJI is associated with significant burden of illness and economic cost. There are a number of well-established modifiable risk factors for PJI. Myriad perioperative protocols are used with the intent of reducing the incidence of PJI. However, it remains unclear why infections occur despite correction of modifiable risk factors and/or adherence to prophylactic protocols. There is emerging evidence that the microbiome-the diverse population of commensal microorganisms that inhabit the human body-may play a role in the pathogenesis of musculoskeletal infections. The impact of the microbiome on PJI warrants further investigation and may change how we conceptualize, prevent, and treat PJI.
Insights
Periprosthetic joint infection (PJI) is a serious complication after joint replacement surgery. Investigating the role of the microbiome may reveal new ways to prevent and treat PJI.
Area of Science:
- Orthopedic Surgery
- Infectious Diseases
- Microbiology
Background:
- Periprosthetic joint infection (PJI) is a severe complication following total joint arthroplasty.
- PJI presents a substantial burden of illness and economic cost.
- Current prevention strategies, including risk factor modification and prophylactic protocols, are not always effective.
Purpose of the Study:
- To explore the potential role of the microbiome in the pathogenesis of PJI.
- To investigate why PJI occurs even when risk factors are managed and protocols are followed.
- To identify novel avenues for PJI prevention and treatment.
Main Methods:
- This study reviews emerging evidence on the microbiome's role in musculoskeletal infections.
- The focus is on understanding the impact of commensal microorganisms on PJI development.
- Further investigation into the microbiome's influence on PJI is warranted.
Main Results:
- The microbiome, comprising diverse commensal microorganisms, is increasingly implicated in musculoskeletal infections.
- Emerging evidence suggests a link between the host microbiome and PJI pathogenesis.
- The precise mechanisms by which the microbiome influences PJI require further elucidation.
Conclusions:
- The microbiome may play a significant role in the development of PJI.
- Understanding the microbiome's impact could revolutionize PJI prevention and treatment strategies.
- Further research is crucial to harness microbiome insights for improved patient outcomes in joint arthroplasty.

Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
