Background: This systematic review investigated the outcomes of revision surgery after periprosthetic ankle infection (PAI). Methods: According to the PRISMA statement, 9 studies with 131 PAIs surgically treated and analyzed were included. Demographics and surgical techniques with eradication rates and complications were reported. Results: Methicillin-sensitive Staphylococcus aureus (MSSA) (30.4%) and coagulase-negative Staphylococcus (CNS) (26.5%) were the most common microorganisms. The eradication rate was 91.7% with permanent antibiotic spacers (SPC), 84.4% with 2-stage, 79.4% with arthrodesis (AA), and 58.8% with debridement and implant retention (DAIR). DAIR showed a significantly lower eradication rate than 2-stage (p = 0.016) and SPC (p = 0.043). Amputations occurred in 25% of patients after SPC, 8.8% after AA and 3.9% after DAIR. SPC showed a significantly higher amputation rate than DAIR and 2-stage (p = 0.044, and p = 0.017, respectively). Conclusions: SPC and 2-stage revision show the highest eradication rates, but 2-stage has a lower risk of amputation.

Abstract

Background: This systematic review investigated the outcomes of revision surgery after periprosthetic ankle infection (PAI). Methods: According to the PRISMA statement, 9 studies with 131 PAIs surgically treated and analyzed were included. Demographics and surgical techniques with eradication rates and complications were reported. Results: Methicillin-sensitive Staphylococcus aureus (MSSA) (30.4%) and coagulase-negative Staphylococcus (CNS) (26.5%) were the most common microorganisms. The eradication rate was 91.7% with permanent antibiotic spacers (SPC), 84.4% with 2-stage, 79.4% with arthrodesis (AA), and 58.8% with debridement and implant retention (DAIR). DAIR showed a significantly lower eradication rate than 2-stage (p = 0.016) and SPC (p = 0.043). Amputations occurred in 25% of patients after SPC, 8.8% after AA and 3.9% after DAIR. SPC showed a significantly higher amputation rate than DAIR and 2-stage (p = 0.044, and p = 0.017, respectively). Conclusions: SPC and 2-stage revision show the highest eradication rates, but 2-stage has a lower risk of amputation.
