This study evaluated the success rate and reinfection in patients with pre-operative culture-negative prosthetic joint infection (PJI) who underwent one-stage revision surgery. The results suggest that the absence of pre-operative pathogen detection may not be a contraindication to one-stage revision in selected patients.
Purpose The main requirement for performing the one-stage septic exchange is the pre-operative identification of the pathogen and its susceptibility. The purpose of this study is to evaluate the success rate with special focus on reinfection in a cohort of patients who underwent one-stage septic knee or hip revision for pre-operative culture-negative PJI. Methods We retrospectively analyzed 640 patients treated by one-stage revision for chronic knee or hip PJI between January 1, 2016, and December 31, 2018. Only cases with pre-operative culture-negative PJI, with culture-negative synovial aspirations and one negative open biopsy, were analyzed. We evaluated the septic and aseptic complication and the rate of complication-free survival defined as the time from the date of first operation and the date of complication events. Results A total of 22 patients fulfilled the inclusion and were enrolled. The mean age of the group was 73.2 +/- 9.8 years, with a median ASA score of 3 (range 3-4). After mean follow-up of 3.6 +/- 2.6 years, 86.4% (19 out of 22) of patients reported no complications. Two patients (9.1%) after one-stage hip required revision arthroplasty due to septic failure, while one patient (4.5%) with one-stage knee had revision for femoral component aseptic loosening. Conclusion Our analysis suggests that the absence of pre-operative pathogen detection may not be contraindication to the one-stage revision in selected patients. The one-stage exchange might be considered in patients with pre-operative negative cultures in presence of ASA > 3 and multiple comorbidities that are not able to tolerate multiple surgeries.
