Radiographs of 72 uncemented hip implants with a mean follow-up of 6.5 years were analysed to measure wear of the implant. The wear rate was measured using the modified technique of Livermore and was found to be 0.13 mm per year (CI 95% 0.080–0.18). There was no statistical correlation between wear and age, gender and cup angle, but there was a correlation(More)
