The Future of Orthopedics:
News, Trends, and Insights from the World of Hip and Knee Replacement and Beyond

Read up on the research transforming total joint arthroplasty – and the BIOLOX® ceramic components shaping the future of patient care. 

Detailed medical illustration presenting the biological impact of wear particles and metal ions in total disc replacement (TDR). The image is bifurcated into two sections: the left side visualizes various wear products and their associated biological responses; the right side highlights the implant design and biomaterial selection in mitigating wear.

What to do about the growing concern of wear particles in spinal implants?

A critical review in iScience by Dr. Joanne L. Tipper (University of Technology Sydney) and Moreica Pabbruwe (Centre for Implant Retrieval and Analysis, Perth) puts spinal implant wear particles in the spotlight.

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.

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).

An infographic showing information and goals about a THR revision study in the UK.

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.
