Osteolysis with Ceramic on Highly Cross-linked Polyethylene

Wear of Highly Cross-linked Polyethylene against Cobalt Chrome and Ceramic Femoral Heads

+*Jennings, L M; *Galvin, A L; *Fisher J +Institute of Medical & Biological Engineering, Leeds, UK [email protected] Introduction There is increasing interest in the coupling of highly cross-linked polyethylene with large diameter heads in the hip, due to the reported lower wear characteristics of highly cross-linked polyethylene compared to conventional polyethylene [1, 2, 3]. Further, ...

Clinical Value Dossier for Longevity Highly Cross-linked Polyethylene

Cross-linked polyethylene and bisphosphonate therapy for osteolysis in total hip arthroplasty: a case report.

A 39-year-old woman underwent bilateral total hip arthroplasty with conventional, ethylene oxide-sterilised liners when she was a subject in a radiostereometric analysis study. Within 2 years she had rapid polyethylene wear with aggressive, asymptomatic, and periprosthetic osteolysis on both sides. Oral alendronate therapy halted the progression of osteolysis over a year and revision to cross-l...

Total Hip Arthroplasty Using Metal Head on a Highly Cross-linked Polyethylene Liner

PURPOSE This retrospective study was performed to evaluate the clinical results and measure polyethylene liner wear in total hip arthroplasty (THA) with highly cross-linked polyethylene. MATERIALS AND METHODS Except for patients who had died or were unable to have follow-up at least 2 years, 60 of 78 hips that underwent THA were included this study. The mean age was 64.5 years (range, 25-81 y...

[Polyethylene particles in synovial fluid after knee arthroplasty with a conventional or highly cross-linked polyethylene. Preliminary study].

AIM OF THE STUDY In recent years cross-linked polyethylenes have been developed in an attempt to reduce the wear, as has been demonstrated in knee simulators. The aim is to assess, by counting particles of polyethylene in synovial fluid, whether the reduction in wear is confirmed in patients with a highly crosslinked polyethylene prosthesis. MATERIAL AND METHODS A prospective randomised study...
