Culture-negative periprosthetic joint infection (PJI) poses a significant challenge in clinical settings. The lack of information on causative organism(s) leads to uncertainties regarding the choice of antimicrobial treatment, which can potentially adversely influence the outcome. Recent advances in molecular-based diagnostic methods have the potential to address the difficulties associated with culture-negative PJIs. These technologies offer a solution to the existing clinical dilemma by providing identification of pathogens and guiding appropriate antimicrobial treatment. In this narrative review, we provide information regarding: 1) incidence and risk factors for culture-negative PJI; 2) the optimal antimicrobial therapy and duration of treatment for culture-negative PJI; 3) outcome comparison between culture-positive and culture-negative PJI; and 4) utilization of novel molecular diagnostic methods in culture-negative PJI, including pathogen identification, and the implementation of an antibiotic stewardship program.

How Often Does Bacteremia Occur in Patients With Chronic Periprosthetic Joint Infection? A Prospective, Observational Study.
Clin Orthop Relat Res
January 2025
Department of Orthopedics, First Affiliated Hospital of Xinjiang Medical University, Urumqi, PR China.
Background: Bacteremia is sometimes observed in patients with prosthetic joint infection (PJI), and it is associated with a lower likelihood of infection control. However, the prevalence and association of bacteremia in chronic PJI remain unknown.
Questions/purposes: (1) What percentage of patients are diagnosed with bacteremia at the time of hospital admission and before surgery for chronic PJI? (2) What clinical factors are associated with positive blood cultures? (3) To what degree are positive blood cultures associated with infection-free implant survival in patients with chronic PJI?
Methods: This prospective study was conducted at a single academic institution from June 2021 to August 2022.

Purpose: The Coronavirus Disease 2019 (COVID-19) pandemic delayed elective procedures such as total joint arthroplasty. As surgical volumes return to prepandemic levels, understanding the implications of COVID-19 becomes imperative. This study explored the effects of COVID-19 on the short-term outcomes of hip arthroplasty.

Introduction Two of the most common complications of joint arthroplasty surgery are aseptic and septic loosening. While aseptic loosening has a well-established treatment protocol, and diagnosis is quite straightforward, bacterial colonization of the implants is associated with a more difficult diagnosis and treatment, more surgeries, and higher morbidity for the patient. Accurate diagnosis is essential in choosing the right treatment plan.

Article Synopsis
- Successful treatment of two rare cases of orthopedic device infections (IMTI) was achieved through careful surgical debridement and 18 months of anti-tubercular chemotherapy while retaining the implants.
- Both patients exhibited similar symptoms, including discharging sinuses at surgical sites years after their respective surgeries, but initial cultures were negative.
- The study highlights the importance of analyzing intra-operative tissue samples for further diagnosis and suggests that atypical presentations of infections should be considered for IMTI in similar cases.
