Charnley-Kerboull Total Hip Arthroplasty Combining Zirconia on Polyethylene A Minimum 2-Year Follow-total hip arthroplasty. To reduce polyethylene wear, P. Boutin introduced alumina ceramic femoral heads in the early 1970’s. However, the relative brittle nature of alumina was responsible for a high rate of fracture. Improvement in the manufacturing process with a low grain size and grain distribut

Highly Cross-linked Polyethylene — A New Option in Tribology of THAtories are very encouraging. Durasul polyethylene inlays showed after 27 million cycles no measurable wear in an AMTI hip simulator study. The ultra-low wear was masked by the minute fluid uptake from the serum. To date, only few in vivo results exist and show a tendency that Durasul resists to wear

The Crosslinked Ultra-high Molecular Weight Polyethylene: Risk and Limitationlene (UHMWPE) articulating against a femoral metallic or ceramic ball or a metallic tibial plateau. Wear of the polyethylene bearing surfaces produces abrasion particles [.], often causing a foreign body response that may lead to bone resorption (osteolysis) and loosening of the components, and ther
