Single-Stage Revision Total Knee Arthroplasty in the Setting of Periprosthetic Knee Infection: Indications, Contraindications, and Postoperative Outcomes.

: Single-stage revision total knee arthroplasty has become an increasingly common treatment option for patients with failed knee prostheses. Periprosthetic knee infection is the leading and most devastating cause of revision total knee arthroplasty. Although periprosthetic knee infection has been extensively studied in the orthopaedic literature, the role of single-stage revision total knee arthroplasty for the treatment of periprosthetic knee infection warrants further research. As healthcare reform shifts from a volume-based to a value-based system, it is imperative that orthopaedic surgeons understand the procedural indications, risks, and benefits of single-stage revision total knee arthroplasty.
