Hi
Welcome to Hip Talk.
You are not too old to have a hip resurfacing if your surgeon thinks you are a good candidate. Men as old as 75 have had hip resurfacings if their bone density and other factors make them good candidates
http://www.surfacehippy.info/agesurvey.php See my age chart of hippies.
I was 61 when I had my hip resurfacing with Dr. De Smet of Belgium in March 2006. I am now 63. Some older ladies have had their hips resurfaced too - one lady I am thinking of was 67.
So hip resurfacing is for the young at heart and those that are candidates for the procedure. It does not necessarily depend on your age.
If you are an active person, you will want a hip resurfacing if possible. It is bone conserving in that they don't cut part of your femur bone off and pound the long stake of a THR hip prothesis into it. You have your whole femur bone left so that if you require a revision later in life you have a complete femur bone for the revision to a THR.
You are lucky that your doctor knows about hip resurfacing and has suggested it. In the US many doctors don't even know about hip resurfacing and many are against it because they dont' understand the process.
You are still young and have much of life ahead of you - get a hip resurfacing and be as active as you can be. That is the purpose of hip resurfacing - to allow you to do any thing you want without worrying about dislocations.
Good Luck with your hip. Please keep us informed about what your sugeon suggests.
