Smith & Nephew reveals new material combination engineered to improve knee implant performance

Smith & Nephew Orthopaedics : 05 March, 2008  (New Product)
Smith & Nephew’s Orthopaedic Reconstruction business has introduced Verilast Technology, which is an optimised material combination engineered specifically to improve knee implant performance and durability.
The technology combines Smith & Nephew's award winning Oxinium material with highly cross-linked polyethylene (XLPE) to produce a one-of-a-kind total knee replacement device.

'Smith & Nephew has a longstanding reputation for providing surgeons with innovative technologies designed to maximise patient outcomes,' said Joseph DeVivo, president of Smith & Nephew Orthopaedic Reconstruction. 'Initial data on Implant wear compared to competitive systems has been very encouraging. Due to the significant improvements we are observing in wear rates over competitive material combinations, a knee with Verilast Technology may be the only Implant many patients ever receive. Combined with our award-winning Oxinium Oxidised Zirconium, the history of innovation in Implant endurance continues with the introduction of our Verilast Technology.'

In lab testing, Smith & Nephew researchers demonstrated that the composition of both articulating surfaces is critical to the performance of the entire bearing couple. When XLPE is combined with Oxinium alloy, significant improvements in wear resistance are both provided and maintained. Smith & Nephew is the only orthopaedic manufacturer that utilises high performance materials in both bearing surfaces to improve knee Implant wear performance.
