Background:
Periprosthetic joint infection (PJI) is a rare but devastating complication after total joint arthroplasty. There is a paucity of data on the incidence and prevalence of periprosthetic infection in mainland China. This study aimed to analyze the rates of surgical revision after arthroplasty due to PJI and the procedures followed in Beijing, China.
Methods:
The study involved a retrospective multicenter cross-sectional survey of patients undergoing revisions for periprosthetic infection after hip/knee arthroplasty at nine hospitals in Beijing from 2014 to 2016. Age, gender, body mass index, primary diagnosis, comorbidity, primary surgery, treatment methods, and post-revision complications were analyzed.
Results:
A total of 38,319 hip/knee arthroplasties and 366 (0.96%) revisions for PJI were identified. Of these, 161 (161/14,110; 1.14%) revisions involved hip arthroplasty, whereas 205 (205/24,209; 0.85%) revisions were due to knee arthroplasty. Procedures for revisions of infected hip included 7 (4.3%) cases of open debridement and prosthesis retention, 32 (19.9%) cases of one-stage exchange, 121 (75.2%) cases of two-stage exchange, and 1 (0.007%) case of hip dissection. As for the infected knee, the procedures included 45 (22.0%) cases of open debridement and prosthesis retention, 13 (6.3%) cases of one-stage exchange, 143 (69.8%) cases of two-stage exchange, and 4 (0.02%) cases of knee fusion.
Conclusions:
The study found the rates of revision due to PJI to be low. Nonetheless, the incidence of PJI in mainland China could be higher and calls for more elaborate studies in geographically and socioeconomically diverse health institutions.
Insights
Periprosthetic joint infection (PJI) rates requiring revision surgery after hip/knee arthroplasty in Beijing were low at 0.96%. Further studies are needed to understand the true incidence of PJI in China.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Epidemiology
- Arthroplasty Outcomes
Background:
- Periprosthetic joint infection (PJI) is a severe complication following total joint arthroplasty.
- Data on PJI incidence and prevalence in mainland China is limited.
- This study addresses the need for data on PJI revision rates in Beijing.
Purpose of the Study:
- To determine the incidence of surgical revision due to PJI after hip and knee arthroplasty in Beijing.
- To analyze the surgical procedures employed for PJI revision in the study cohort.
Main Methods:
- Retrospective multicenter cross-sectional survey.
- Involved nine hospitals in Beijing, China, covering 2014-2016.
- Analyzed patient demographics, diagnoses, comorbidities, surgical procedures, and post-revision outcomes.
Main Results:
- A total of 38,319 hip/knee arthroplasties were reviewed, with 366 (0.96%) requiring revision for PJI.
- Hip arthroplasty revisions for PJI were 1.14% (161/14,110), while knee arthroplasty revisions were 0.85% (205/24,209).
- Two-stage exchange was the most common procedure for both hip (75.2%) and knee (69.8%) PJI revisions.
Conclusions:
- The study identified low rates of revision surgery for PJI in Beijing.
- The actual incidence of PJI in mainland China may be underestimated.
- Further comprehensive research is recommended across diverse Chinese health institutions.
