Abstract
We evaluated 162 hips with osteonecrosis of the femoral head that had undergone THA using highly
cross-linked polyethylene liner after a minimum follow-up of 5 years. Neither femoral nor acetabular
components displayed radiographic evidence of mechanical loosening or osteolysis, and no components
had been revised at the latest follow-up. The mean rate of linear liner wear was 0.038 mm/year.
Univariate regression analysis did not demonstrate that age, gender, weight, activity level or cup
inclination had any influence on penetration. While the long term effects of altered mechanical properties
of highly cross-linked PE remain unknown, the clinical and radiographic results at a minimum of 5 years
are promising for this high-risk population.
