Retrospective cohort study of 117 patients who completed two-stage exchange arthroplasty for infected TKA at a single referral center (1997–2007), analyzing 15 presurgical and 11 operative variables to identify predictors of treatment failure, defined as any reoperation for recurrent PJI.
When planning two-stage exchange for infected TKA, counsel patients that failure rates approach 28% — and when cultures are negative or grow resistant organisms, warn them the risk is even higher.
Don't rely on normalized ESR/CRP alone to clear a patient for reimplantation; these markers did not predict success in this series.
