June 10th 2025 25 years of proof: Ceramic-on-ceramic bearings go the distance Murphy et al. confirm CoC bearings outlast alternatives in young THA patients Read more
June 5th 2025 BIOLOX®delta CoC resurfacing could ease the burden of follow-up costs First study outlines potential cost advantage of ceramic resurfacing follow-up protocols over metal resurfacing. Read more
May 29th 2025 BIOLOX®delta delivers fracture-free implant rates after 14 years A new multi-center study (Worthing, Lister, Cairo University) in the European Journal of Orthopaedic Surgery & Traumatology has confirmed what many surgeons know: Ceramic-on-ceramic bearings made of BIOLOX®delta perform – and last.

May 14th 2025 PEEK-on-ZTA ceramic returns strong five-year results in cervical total disc replacement Dr. Richard Guyer and team from the Center for Disc Replacement at Texas Back Institute conducted a clinical trial evaluating the five-year follow-up of single-level PEEK-on-ZTA ceramic cervical TDR procedures against a control group of propensity-score-matched anterior cervical discectomy and fusion (ACDF) procedures. The material focus of this study was the Simplify Cervical Artificial Disc from Globus/NuVasive, made with zirconia-toughened-alumina (ZTA) ceramic. Read more
May 9th 2025 How does cobalt-chromium-molybdenum (CoCrMo) wear contribute to cellular corrosion? An in vitro study and its implications for joint replacement With support from AAHKS, Dr. William Mihalko, PhD, and a research team at the University of Tennessee Health Science Center set out to answer this question by conducting an in vitro examination of biological responses to simulated CoCrMo wear particles and their role in inflammatory cell-induced corrosion (ICIC).

April 24th 2025 New UK study shows THR revision least likely with BIOLOX®delta ceramic bearings Sourcing from one of the world’s largest registries – the UK’s National Joint Registry – Dr. Whitehouse and team at the University of Bristol Medical School have analyzed the efficacy of multiple bearing surface materials in primary total hip replacement (THR). They analyzed 1,026,481 THRs performed from 2003-2019, 2% of which (20,869) required revision. Read more
April 17th 2025 Bearing Selection in Hip Revision: Why It Matters for Long-Term Success Prof. Simon Marmor and team from the Department of Orthopedic Surgery, Groupe Hospitalier Diaconesses Croix Saint-Simon in Paris faced an unusual case of a painful hip with tissue pigmentation on a 68-year-old male patient, which had been revised with a metal bearing three years earlier in another institution.

December 5th 2024 Metal release in the knee: A greater burden than suspected? An interdisciplinary US team – including Clemson University’s Jeremy Gilbert, PhD, Drexel University’s Steve Kurtz, PhD, and the University of Tennessee’s William Mihalko, MD, respectively in Clemson, Philadelphia, and Memphis – have studied the mechanisms that cause the deterioration of cobalt-chrome-molybdenum (CoCrMo) and titanium components in total knee arthroplasty (TKA) and releasing metal ions in vivo. They conclude that ALTRs, electrocautery damages, and other damages may interfere as dangerously in primary TKA implants as in hip implants. Read more
September 16th 2024 Surgeons can expand their options with 40mm BIOLOX®delta CoC heads and bearings Finding optimal head and bearing sizes is an ongoing journey in total hip arthroplasty (THA). Large-diameter ceramic-on-ceramic (CoC) bearings may improve function and implant stability while minimizing wear concerns, and there is a growing body of evidence to support the implementation of larger sizes.
