I find it important to provide the most reliable information available on the Surface Hippy Website. Since it started in 2005, there have been a variety of hip resurfacing devices available.  Only three have been approved by the FDA. The information posted on Surface Hippy is based on National Registry Information, Medical Studies and Surgeon Articles. Unfortunately, some hip resurfacing devices have not provided good outcomes to patients and have been removed from the market.  As hip resurfacing devices continue to be used, there is now a longer history of outcomes available up to 10 years reported in the Australian Orthopaedic Association National Joint Replacement Registry 2013. The ASR was removed from the market.  The Corin Cormet had very poor results according to the Australian 2013 National Registry. I decided to no longer provide detailed information about devices that had poor outcomes and the surgeons using them.  That decision does not indicate that a patient won’t have an excellent outcome with those devices and that they can not have a successful surgery by surgeons choosing to use those devices. That decision means that I want to help people learn about hip resurfacing and excellent outcomes.  I want to provide detailed information about successful hip resurfacing devices and the surgeons that choose to use them.
