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.
