The algorithm of metaphisal fixator choice in revision knee arthroplasty

The aim of this research was to study the immediate and long-term outcomes of revision total knee replacement (reTNR) using metaphyseal fi tors (sleeves and cones), and to design the algorithm for choosing a metaphyseal fi tor. Material and methods. The research involved 134 patients who underwent revision knee arthroplasty. The patients were divided into two groups according to the type of metaphyseal fi tor used for their surgeries: sleeves (Group1) - 97 patients, and cones (group 2) - 37 patients. The outcomes were evaluated at their discharge from the hospital, 6, 12, 24 months after surgeries. The implants survival was analyzed with the Kaplan-Meier estimate. Reoperation with the complete replacement of the implant or its components was considered a critical event.
