These numbers were all from the Australian Hip Registry which was established in 1999. A total of 140,018 patients registered with 160349 procedures out of which 8361 were resurfacings.

The BHR was started in 1999 and the competitors started in 2000 and 2001. This is the latest data published in that registry. I am sure there are more details in the registry itself, but this is all the data, well minus 1% of resurfacing done in Australia. I think it is somewhat a good overall feel for the results considering it is gathered over almost the same amount of time, from all of Australia in all patients given the procedure which would cover all doctors, etc.
