Healthcare Industry News: oxidized zirconium
News Release - June 18, 2020
Smith & Nephew announces new milestone with its OXINIUM(TM) Advanced Bearing System implants surpassing two million proceduresLONDON, June 18, 2020 -- (Healthcare Sales & Marketing Network) -- Smith & Nephew (LSE:SN,NYSE:SNN), the global medical technology business, today announced that over two million patients have been treated with implants made from OXINIUM Technology - a proprietary oxidized zirconium alloy used in hip and knee replacements.
OXINIUM is a unique material that combines the strength of metal with the wear resistance of ceramic. Its hardness, low-friction and resistance to roughening and abrasion makes it ideal for a wide variety of hip and knee applications. OXINIUM's combination of long-term durability and wear resistance has propelled Smith & Nephew's reconstruction portfolio over the last two decades.
"Smith & Nephew is proud to have an extensive history of innovation, highlighted by one of the flagship bearing materials in all of orthopaedics. OXINIUM has helped over two million patients get back on their feet and we look forward to seeing millions more live their life unlimited in the future," said Randy Kilburn, Smith & Nephew Senior Vice President of Global and Commercial Marketing, Orthopaedics.
The evidence speaks for itself:
- Four major registries around the world have shown OXINIUM to be the best performing hip bearing on the market.1-4
- From three months on, OXINIUM Technology with XLPE significantly reduces the revision risk in total hip arthroplasty by 29% compared to Metal/XLPE (p<0.001).1
- The only bearing technology with published results of 45 Million Cycles knee in vitro wear simulation testing, simulating 30 years of normal activity.5,6
- Over 34 published studies showing excellent long-term survivorship, including lower damage scores in knee retrieval analysis, and better results when compared to cobalt chrome.7,8
- POLAR3™ Total Hip Solution - The combination of POLARSTEM™ cementless stem and the R3™ Acetabular System, featuring the proprietary OXINIUM™ oxidized zirconium on XLPE bearing couple, that provides improved patient reported outcomes with high survivorship at eight years.9
- OR3O™ Dual Mobility System - Utilizing new OXINIUM™ DH (Diffusion Hardened) Technology, the OR3O dual mobility hip system is designed to minimize corrosion concerns, maximize stability and reduce the risk of dislocation.
- JOURNEY™ II Total Knee System - Designed to replicate normal anatomy and help patients rediscover normal through smoother recovery10, improved function11-14 and higher patient satisfaction.10,11,15,16
- JOURNEY II Unicompartmental Knee - Next generation unicondylar platform that leverages strong clinical history with modernized instrumentation and OXINIUM Technology.1,17,18
Introduced in 1995, OXINIUM Technology has nearly 25 years of clinical heritage and is one of the many innovations driving Smith & Nephew's advanced hip and knee portfolio. In 2005, OXINIUM Technology was the first and only medical device material to receive the prestigious Engineering Achievement Materials Award from ASTM International.

- The LEGION™ Primary CR Knee System completed 45 million cycles of in vitro simulated wear testing, which is an estimate of 30 years of activity. Other LEGION VERILAST Primary Knee Systems underwent similar lab testing comparable to industry standards. The results of in vitro wear simulation testing have not been proven to quantitatively predict clinical wear performance. Also, a reduction in total polyethylene wear volume or wear rate alone may not result in improved clinical outcomes as wear particle size and morphology are also critical factors in the evaluation of the potential for wear mediated osteolysis and associated aseptic implant loosening. Particle size and morphology were not evaluated as part of the testing.
