Naito Y, Hasegawa M, Tone S, et al. - This study was undertaken to investigate clinical and radiographic results of cementless total hip arthroplasty using a 32-mm cobalt-chromium head-on remelted highly cross-linked polyethylene (HXLPE) and a tapered, fiber metal proximally coated femoral stem at a mean follow-up of 12 years. Researchers conducted a total of 57 cementless total hip arthroplasties using remelted HXLPE combined with a 32-mm cobalt-chromium head, and a tapered, fiber metal proximally coated femoral stem between October 2004 and December 2006. They conducted a clinical assessment applying the Merle d’Aubigné and Postel scoring system. They examined standardized anteroposterior and lateral radiographs of the pelvis and femur without weight-bearing. At long-term follow-up, a 32-mm cobalt-chromium head-on remelted HXLPE demonstrated low wear properties, and a tapered, fiber metal proximally coated femoral stem exhibited good outcomes.
