Patients were randomised to be treated with a cobalt-chrome (CoCr) femoral head with an ultra-high molecular weight polyethylene (UHMWPE), highly cross-linked polyethylene (XLPE) or ceramic-on-ceramic (CoC) bearing surface.\nPATIENTS AND METHODS: A total of 102 hips (91 patients) were randomised into the three groups. At ten years, 97 hips were available for radiological and functional follow-up. Two hips (two patients) had been revised (one with deep infection and one for periprosthetic fracture) and three were lost to follow-up. Radiological analysis was performed using a validated digital assessment programme to give linear, directional and volumetric wear of the two polyethylene groups.\nRESULTS: There was a significantly reduced rate of stea","tracks":[{"project":"PubMed_Structured_Abstracts","denotations":[{"id":"T1","span":{"begin":162,"end":539},"obj":"OBJECTIVE"},{"id":"T2","span":{"begin":562,"end":1014},"obj":"METHODS"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubMed_Structured_Abstracts"},{"subj":"T2","pred":"source","obj":"PubMed_Structured_Abstracts"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"PubMed_Structured_Abstracts","color":"#ecb493","default":true}]}]}}
