Braun Ltd, Sheffield, United Kingdom) and a conventional metal-on-polyethylene articulation. The main indications for THR were primary or secondary osteoarthritis. <\/jats:p><jats:p> At follow-up after a mean 11.6 years (7.6 to 18.4) 17 patients had died and 20 could not be traced leaving a final series of 280 THRs in 250 patients. There were 62 revisions (22.1%) in 59 patients. A total of 43 acetabular shells (15.4%) had been revised and 13 (4.6%) had undergone exchange of the liner. The most frequent indications for revision were osteolysis and aseptic loosening, followed by polyethylene wear. The mean Kaplan-Meier survival of the Plasmacup was 91% at ten years and 58% at 14 years. Osteolysis was found around 36 (17.1%) of the 211 surviving shells. The median annual rate of linear wear in the surviving shells was 0.12 mm\/year and 0.25 mm\/year in those which had been revised (p &lt; 0.001). Polyethylene wear was a strong independent risk factor for osteolysis and aseptic loosening. The percentage of patients with osteolysis increased proportionately with each quintile of wear-rate. <\/jats:p><jats:p> There is a high late rate of failure of the Plasmacup. Patients with the combination of this prosthesis and bearing should be closely monitored after ten years. <\/jats:p>","DOI":"10.1302\/0301-620x.92b6.23666","type":"journal-article","created":{"date-parts":[[2010,5,31]],"date-time":"2010-05-31T23:23:17Z","timestamp":1275348197000},"page":"856-861","source":"Crossref","is-referenced-by-count":31,"title":["Long-term outcome of a cementless, hemispherical, press-fit acetabular component"],"prefix":"10.1302","volume":"92-B","author":[{"given":"N.
