Long-term survival of a flat-on-flat total condylar knee arthroplasty fixed with a hybrid cementing technique for tibial components

Total knee arthroplasty is one of the most successful procedures of modern orthopedics. Several implants have been proposed over the years with different designs, kinematics, and cementing techniques, with good results. The aim of the study was to assess the clinical and radiographic long-term follow-up of a series of patients undergoing total knee replacement that used a specific design of knee implant with cemented femoral and patellar components, and a hybrid fixation technique for tibial trays that used a cemented base plate and press-fit keels.
