Does choice of bearings influence the survival of cementless total hip arthroplasty in patients aged 20-55 years? Comparison of 21,594 patients reported to the Nordic Arthroplasty Register Association dataset 2005-2017. Acta Orthop. (IF 3.7) Pub Date : 2023-06-05 Rasmus Tyrsted Mikkelsen,Søren Overgaard,Alma B Pedersen,Johan Kärrholm,Ola Rolfson,Anne Marie Fenstad,Ove Furnes,Geir Hallan,Keijo Mäkelä,Antti Eskelinen,Claus Varnum
BACKGROUND AND PURPOSE The bearings with the best survivorship for young patients with total hip arthroplasty (THA) should be identified. We compared hazard ratios (HR) of revision of primary stemmed cementless THAs with metal-on-metal (MoM), ceramic-on-ceramic (CoC), and ceramic-on-highly-crosslinked-polyethylene (CoXLP) with that of metal-on-highly-crosslinked-polyethylene (MoXLP) bearings in patients
