Survivorship of ceramic-on-ceramic total hip arthroplasty with metal-backed acetabular liners at 10 years
Journal of Arthroplasty Jun 28, 2021
Wagner M, Schönthaler H, Endstrasser F, et al. - This study was undertaken to investigate a metal-backed liner implant system for primary total hip arthroplasty (THA). Researchers enrolled a total of 422 patients (with 468 consecutive THAs) who were followed over a mean period of 10 years. Researchers conducted all arthroplasties with a cementless stem, a press-fit cup, and a metal-backed liner system. They examined surgical and clinical data, complications, and revisions. They compared Western Ontario and McMaster Universities Osteoarthritis Index before surgery and at 1 and 10 years after surgery. This study’s findings demonstrate that THA using cementless stem, press-fit cup, and metal-backed liner system provides satisfactory long-term outcomes, with revision rate comparable to that with other systems available in the market. It was shown that the metal-backed liner system has a low risk of mal-seating. In addition, third-generation ceramic liners should be avoided as they appear to be more prone to breakage.
