Survivorship Rates for Hip Resurfacing from National Registries
Australian Orthopedic Association National Registry 2011
The cumulative percent revision at ten years for primary total resurfacing hip replacement undertaken for osteoarthritis is 7.5%
There are six prostheses with over 1,000 observed component years, the ASR, Adept, BHR, Cormet, Durom and Mitch TRH. At seven years, the BHR has the lowest cumulative percent revision (5.0%) compared to Cormet (11.1%), Durom (9.6%) and ASR (13.0%). The BHR is the only resurfacing prosthesis with a cumulative percent revision at ten years (6.3%).

McMinn/Treacy series at 10 years –BHR survivorship is 99.74%
Mr McMinn’s results with the BHR show a 97% survival in men
