Licence agreement concerning inclusion of doctoralSafety of Orthopedic Implants: Implant Migration Analysis a Must • May 3rd, 2024
Contract Type FiledMay 3rd, 2024In total knee arthroplasty (TKA), metal-backed (MBT) and all-polyethylene (APT) designs have shown comparable implant migration up to 2 years using radiostereometric analysis (RSA). However, studies comparing mid-term migration of both designs are lacking. Furthermore, continuously migrating TKAs up to 2 years may continue to migrate or stabilize hereafter. Therefore, we compared 5-year migration of MBT and APT using either cruciate-stabilizing (CS) or posterior- stabilizing (PS) designs and specifically assessed migration profiles of continuously migrating TKAs beyond 2 years.
