One-stage d[eacute]bridement and knee fusion for infected total knee arthroplasty using the hybrid frame

In 1997 and 1998, a hybrid fixator was used for a one-step arthrodesis in 2 cases of infected total knee arthroplasty. One patient had rheumatoid arthritis, and the other had an infected reimplant arthroplasty. Neither patient was a candidate for reimplantation. Fusions were achieved with the hybrid frame in an average of 10 weeks. All signs of local and systemic infections were eliminated. After 24 months for patient 1 and 37 months for patient 2, both are infection-free and ambulatory without the aid of a wheelchair.
