Zimmer's Longevity Highly Crosslinked Polyethylene Demonstrates Long-Term Clinical Success

Zimmer Holdings, Inc. ZMH today announced that results of an independent study presented at the 2011 American Academy of Orthopaedic Surgeons (AAOS) annual meeting demonstrated long-term clinical success for Longevity® Highly Crosslinked Polyethylene. The study, by a team from the Massachusetts General Hospital, included radiographic analysis from a 299 patient cohort receiving primary total hip arthroplasties using Zimmer's Durasul® or Longevity Highly Crosslinked Polyethylene liners. It is the largest series and longest follow-up period to date for highly crosslinked polyethylene material. Radiographic results presented in the study indicate very low wear in vivo with no signs of change over time and no signs of periprosthetic osteolysis in the patient cohort.
