Abstract

Purpose: Single-stage revision has gained significant attention as a major surgical approach for periprosthetic joint infection (PJI). However, the 90-day mortality and complication profile of single-stage revision is poorly characterized. The purposes of this study were to determine the incidence rates of and identify the risk factors for 90-day postoperative mortality and complications of single-stage revision for chronic PJI.

Methods: A retrospective review was conducted on patients who underwent single-stage revision for PJI between August 2000 and May 2022. Patient demographics, 90-day mortality, and postoperative complications were recorded. Complications were categorized into systemic and local complications. Patients in this study were further categorized into knee and hip revision groups. Univariate and multivariate logistic regression analyses were performed to identify significant independent predictors of the outcome measures.

Results: 348 patients (144 knees and 204 hips) were included in this study. The 90-day mortality rate was 0.9%. The incidence rates of postoperative complications in knee and hip surgeries were 31.3% and 19.6%, respectively. The most common complication was deep-vein thrombosis (DVT). Rheumatoid arthritis (RA) was the independent predictor of mortality. In the knee revision group, fungal infection was identified as the independent predictor of recurrent PJI; regular alcohol use was predictive of wound dehiscence. Among hip PJI patients, age ≥ 80 years was independently associated with DVT; RA was found to be a predictor of dislocation and wound dehiscence.

Conclusion: For continuous and unselected patients with chronic PJI, single-stage revision demonstrated a satisfactory 90-day mortality. Nevertheless, the 90-day postoperative complication rates after single-stage revision in both knee and hip groups were relatively high.
