The mean clinical and radiological follow-up was 13.4 years (12 to 15). A Profile hydroxyapatite-coated anatomical femoral component was used in each case. Six patients had a late dislocation, for whom the polyethylene liner was exchanged. Each acetabular component was well fixed and all femoral components showed signs of bone ingrowth. The mean rate of femoral head penetration was 0.10 mm\/year (0.021 to 0.481). The probability of not developing femoral cortical hypertrophy and proximal osteopenia by 12 years was 80.2% (95% confidence interval, 72.7 to 87.6) and 77.5% (95% confidence interval, 69.7 to 85.2), respectively. Despite these good clinical results, further follow-up is needed to determine whether these prostheses will loosen with time. <\/jats:p>","DOI":"10.1302\/0301-620x.91b3.20947","type":"journal-article","created":{"date-parts":[[2009,3,3]],"date-time":"2009-03-03T22:48:56Z","timestamp":1236120536000},"page":"327-332","source":"Crossref","is-referenced-by-count":20,"title":["Outcome of a hemispherical porous-coated acetabular component with a proximally hydroxyapatite-coated anatomical femoral component"],"prefix":"10.1302","volume":"91-B","author":[{"given":"E.","family":"Garc\u00eda-Rey","sequence":"first","affiliation":[{"name":"Hospital La Paz, P\u00b0 Castellana 261, 28046 Madrid, Spain."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Garc\u00eda-Cimbrelo","sequence":"additional","affiliation":[{"name":"Hospital La Paz, P\u00b0 Castellana 261, 28046 Madrid, Spain."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Cordero-Ampuero","sequence":"additional","affiliation":[{"name":"Hospital La Princesa, Diego de Le\u00f2n 62, 28006 Madrid, Spain."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"42","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200112000-00007"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1054\/arth.2001.23921"},{"key":"R3","doi-asserted-by":"crossref","unstructured":"Astion DJ, Saluan P, Stulberg BN, Rimnac CM, Li S.
