Superior Survival of Fully Cemented Fixation Compared to Hybrid Fixation in a Single Design Rotating Hinge Knee Implant

Dataset with 275 RT-PLUS® rotating hinge knee implants (Smith and Nephew, Memphis, TN, USA) in 269 patients (60 primary procedures, 215 revisions). Of the 275 implants, 248 had a uniform fixation technique for both components (148 fully hybrid, 100 fully cemented), while 27 implants had a mixed fixation technique for the components (15 hybrid femur and fully cemented tibia, 12 fully cemented femur and hybrid tibia). Outcome was revision for aspectic loosening. The median follow-up was 7.3 ± 3.9 years, with a minimum of 2 years for non-failed implants.
