Characterization of Outcomes of 2-Stage Exchange Arthroplasty in the Treatment of Prosthetic Joint Infections

Two-stage revision does not result in the high rates of cure reported previously, when taking into account the substantial number of patients who never undergo the subsequent reimplantation surgery. Of those who underwent reimplantation in our study, many required additional spacer exchange or had complications. Surgeons and patients should consider these outcomes when discussing the treatment of prosthetic hip and knee infections.
