title: [Long-term results after Charnley hip replacement].
abstract: We made a prospective study of 241 Charnley total hip replacements performed between 1968 and 1974. In 1990 we reviewed 92 patients with 103 hips or 96% of surviving hips at a mean follow-up of 17.6 years (15 to 20.6). The clinical results were excellent with Charnley scores of four or more for pain in 95% of the cases, for function in 73% and for movement in 93%. Of the whole series, 8.3% had been revised and Kaplan Meier survival analysis showed a probability of revision at 20 years of 10.7%. No significant difference concerning the results was found between young patients operated between the ages of 34 to 55, and older patients operated between the ages of 56 to 79 years. These results are similar to those from the few other series with extended follow-up and make it difficult to justify the present widespread use of uncemented hip prostheses.
