Two-Stage Revision Total Knee Arthroplasty in the Setting of Periprosthetic Knee Infection.

Two-stage revision total knee arthroplasty (TKA) is the standard of care for patients who require a revision procedure for the mangement of a late or chronic periprosthetic knee infection. A careful examination of two-stage revision TKA is warranted as the number of patients who require revision TKA in the United States continues to rise. Surgeons should understand the intricacies involved in two-stage revision TKA, including the indications, procedural variations, and current deliberations on two-stage revision TKA in the literature. Surgeons also should understand the alternative treatments for periprosthetic knee infections.
