Continued Stabilization of a Cementless 3D-Printed Total Knee Arthroplasty : Five-Year Results of a Randomized Controlled Trial Using Radiostereometric Analysis
BACKGROUND: Three-dimensional (3D) printing of highly porous orthopaedic implants aims to promote better osseointegration, thus preventing aseptic loosening. However, short-term radiostereometric analysis (RSA) after total knee arthroplasty (TKA) has shown higher initial migration of cementless 3D-printed tibial components compared with their cemented counterparts. Therefore, critical evaluation o
