Summary
Rheumatoid arthritis and sepsis significantly increase the risk of developing a second prosthetic joint infection. This retrospective study highlights key risk factors for multiple prosthetic infections in patients undergoing arthroplasty.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Epidemiology
- Rheumatology
Background:
- Multiple prosthetic joint infections pose a significant clinical challenge.
- Identifying risk factors for secondary infections is crucial for patient management.
Purpose of the Study:
- To assess risk factors associated with the development of multiple prosthetic infections.
- To investigate the relationship between underlying diagnoses and recurrent prosthetic infections.
Main Methods:
- Retrospective analysis of 145 patients with 174 deep prosthetic infections between 1981 and 1993.
- Evaluation of patient demographics, underlying diagnoses, and comorbidities.
- Statistical analysis to determine associations with second prosthetic infections.
Main Results:
- An overall incidence of 19% for a second prosthetic infection was observed.
- Rheumatoid arthritis and major nonprosthetic infections (sepsis) were significantly associated with multiple prosthetic infections (P < .001 and P = .0001, respectively).
- Patients with rheumatoid arthritis and multiple infections showed poorer functional status (ARA Class III/IV).
Conclusions:
- Rheumatoid arthritis and sepsis are critical risk factors for developing subsequent prosthetic joint infections.
- The timing of presentation for multiple infected implants suggests a potential link to systemic infection.
- Accurately quantifying the risk from one infected arthroplasty to others remains challenging.
