I have scheduled to have one of my hips replaced by dr gross very soon.
He previously replaced one of my hips a decade ago, and it is still going strong and I have had no complications. My natural tendency would be to do the same thing I did last time since the result has been so great.
In looking at the website, there are more recent developments, suggesting that Madeline Cross poly could be superior to metal on metal. I believe Dr. Gross is still using a metal on metal Biomet implant.
What is the current consensus on the ideal implant? Mom? Metal on cross poly?
Are surgeons going away from metal on metal if that is the case why is Dr. Gross still using it?
I just met with a full cadre of the top surgeons, Pritchett, Gross, Su, De Smet. All except Pritchett suggested MoM was the best bet for highly active folks. Pritchett prefers the cross poly. I am not sure why exactly. He states the metal ions, but it could also be another reason. For ex. easier to install, with more margin for error.
Metal on Metal is the industry standard and probably will be for a long time. The BHR, the Wright C+ and Biomet are the most popular. There are a few others. Only the BHR is FDA approved in the US. The Biomet is used because both components are FDA approved, but not approved as a full device. Strange! The Wright C+ is no long in the US. So it will stay the gold standard for a long time. The long term outcomes for metal on metal are very good when done by an experienced surgeon.
It takes years for a device to be approved by the FDA in the US. So you won't see anything new very quickly. JointMedica’s Polymotion® Hip Resurfacing System is currently going through a process with the FDA to be able to used in studies. It takes years for FDA approval. So nothing is expected in the near future. https://surfacehippy.info/category/hip-resurfacing/hip-resurfacing-devices/jointmedicas-polymotion-hip-resurfacing-system/ (https://surfacehippy.info/category/hip-resurfacing/hip-resurfacing-devices/jointmedicas-polymotion-hip-resurfacing-system/) It has a vitamin E crosslinked polyethylene liner.
There are also several ceramic on ceramic hip resurfacing devices on trial overseas. https://surfacehippy.info/category/hip-resurfacing/hip-resurfacing-devices/recerf-ceramic-hip-resurfacing-device/ (https://surfacehippy.info/category/hip-resurfacing/hip-resurfacing-devices/recerf-ceramic-hip-resurfacing-device/) https://surfacehippy.info/category/hip-resurfacing/hip-resurfacing-devices/h1-ceramic-hip-resurfacing-device/ (https://surfacehippy.info/category/hip-resurfacing/hip-resurfacing-devices/h1-ceramic-hip-resurfacing-device/) But none in the US.
So the FDA moves slowly and most newer devices will only be available in trials.
I hope that gives you a little more info. I wish you the best.
Well I have both so I guess I will be the guinea pig. I had the Birmingham implanted 12 years ago and the EndoTec ceramic device 8 months ago. Both were done by Dr. Pritchett. He gave me the choice and some links to the research. After studying it a bit I decided to go with the ceramic on the second device. So far the only difference I note is that I seem to have more range of motion with the ceramic device but this could be due to other factors also.
