Knee Arthrodesis for Recurrent Periprosthetic Knee Infection

Knee arthrodesis for recurrent periprosthetic knee infection is a limb salvage procedure that simultaneously provides a stable limb for weight-bearing and effective eradication of the chronic infection. Knee arthrodesis is a final resort for limb salvage that is appropriate for patients with multiple recurrent revisions for infection, a history of failed 2-stage exchanges, medical comorbidities, and an inability to tolerate multiple additional procedures. Another important consideration is whether the patient has a poor soft-tissue envelope that leaves knee arthrodesis as the only viable option. The procedure is a definitive surgery to eliminate return trips to the operating room.
