The treatment of recurrent chronic infected knee arthroplasty with a 2-stage procedure.

We report the case of a patient with recurrent periprosthetic infections after total knee arthroplasty associated with bone destruction and massive bone loss that was successfully treated with a 2-stage procedure-resection arthroplasty with insertion of an antibiotic-impregnated cement rod-spacer and systemic antibiotics and then a resection arthrodesis of the knee with the use of an intercalary allograft fixed with a long intramedullary nail. This technique is a viable option for the treatment of recurrent periprosthetic infections after total knee arthroplasty associated with bone destruction, massive bone loss, and severe instability.
