Knee arthrodesis by the Ilizarov method in the treatment of total knee arthroplasty failure

In our experience, the Ilizarov method is effective for performing a knee arthrodesis in the case of extensive bone loss. At the same time, it is possible to correct the associated leg deformities or limb length difference. In addition, only the Ilizarov method provides a mechanical stimulus for bone formation and improves the quality of the bone and of the microcirculation, which enhances the host response against infection. Despite these attributes, knee arthrodesis by the Ilizarov method must be considered a 'salvage procedure' in cases of severe outcomes from knee surgery in which revision arthroplasty is not indicated.
