Wear Performance Improvement

Laboratory testing on wear simulators shows a 96% wear reduction over the leading competitive premium bearing technology with the combination of Stryker's X3 Advanced Bearing Technology and the Scorpio Knee System.1 Implant wear is one of the non-patient related causes of implant failure. By helping to reduce wear, these implants have a potential to be long lasting.

No statistical difference was found for Tensile Yield Strength, Ultimate Tensile Strength and Elongation as measured per ASTM D638 before and after exposure to ASTM F2003 accelerated aging (5 Atmospheres (ATM) of oxygen at 70ºC for 14 days). Tensile Yield Strength was 23.5 +/- 0.3 MPa and 23.6 +/- 0.2 MPa, Ultimate Tensile Strength was 56.7 +/- 2.1 MPa and 56.3 +/- 2.3 MPa and Elongation was 267 +/- 7% and 266 +/- 9% before and after accelerated oxidative aging, respectively.
