Their mean age was 21 years (11 to 35). All the patients were reviewed clinically and radiologically at one, three and five years. At the final review at a mean of 11.2 years (8 to 13) 37 hips in 23 patients were available for assessment. <\/jats:p><jats:p> A total of four femoral components (9.5%) had failed, of which two were radiologically loose and two were revised. The four failed components were in patients aged 16 years or less at the time of surgery. Hydroxyapatite-coated customised femoral components give excellent medium- to long-term results in skeletally-mature young adults with inflammatory polyarthropathy. Patients aged less than 16 years at the time of surgery have a risk of 28.5% of failure of the femoral component at approximately ten years. <\/jats:p>","DOI":"10.1302\/0301-620x.88b7.17046","type":"journal-article","created":{"date-parts":[[2006,6,23]],"date-time":"2006-06-23T19:55:49Z","timestamp":1151092549000},"page":"860-864","source":"Crossref","is-referenced-by-count":24,"title":["The use of hydroxyapatite-coated CAD-CAM femoral components in adolescents and young adults with inflammatory polyarthropathy"],"prefix":"10.1302","volume":"88-B","author":[{"given":"C.
