What We Led, What We Said, What We Proved What We Led As pioneers in wear reduction technology, Stryker Orthopaedics has consistently been the market leader in providing a variety of polyethylene bearing material improvements. This includes:

Duration® Stabilized Polyethylene X3™ Highly Crosslinked Polyethylene Launched in 1996, Duration® Stabilized Polyethylene is produced by a patented process utilizing a combination of nitrogen packaging to reduce shelf oxidation, gamma irradiation (3 MRads) to sterilize and crosslink the polyethylene, and a postirradiation stabilization step during which the components undergo a heat treatment process to promote further crosslinking to enhance product wear resistance. An evolution of both the Duration® and Crossfire® technologies, X3™ Highly Crosslinked Polyethylene was introduced in 2005. The...

What We Led, What We Said, What We Proved What We Said The Stryker® Orthopaedics hip simulators were designed to simulate the anatomical positioning, physiological loading, cross shear motion and biological environment (lubricant) of the human hip joint. Comprehensive laboratory studies, including a series of hip simulator wear tests have resulted in an optimized set of test parameters and have been the basis for predicting clinical outcomes.1, 2, 3 Duration® Stabilized Polyethylene • Hip simulator testing demonstrates approximately 30% wear reduction for Duration® liners in comparison with gamma-in-air...

What We Led, What We Said, What We Proved What We Proved The clinical success of Stryker® Orthopaedics bearing technologies have been highlighted in many clinical trials. John Martell, MD10 • Multicenter, prospective, randomized study of the clinical performance of Crossfire® Polyethylene hip components with conventional polyethylene, at a 2-3 year follow-up demonstrated a statistically significant reduction of linear wear rates in the highly crosslinked polyethylene products compared with conventional polyethylene products • 2-year results show a 50% reduction in head penetration for Crossfire®...
