Hi Tam, Stewart had one hip done with the Birmingham Hip Resurfacing technique (lots of info if you google it- wikipedia is good).

He had his done about 7 years ago, so he'd have been 54. This was all on the NHS, and as suggested by his consultant.
As far as I gathered, with this resurfacing they stick a sheet of titanium over the damaged area, so it is far less destructive than taking the bone away, so recovery is better.

He's been very happy with it.

Good luck with whatever you have done.
