My breaking point occurred when, after suffering through several years of increasing pain and discomfort, I finally realized I couldn't even play nine holes of golf without being, essentially, disabled for the rest of the day and very stiff the next day (I had always been very active). I finally saw a respected orthopaedist to whom I was referred, who only does THR's. He showed me the x-rays (basically, no cartilage remained in my left hip joint and very little in the right) and told me it wasn't a question of whether I needed to deal with the problem but, rather, a question of whether I was prepared mentally/emotionally to deal with it. He prescribed a N-SAID, which provided some short-term relief, and sent me on my way.
I was 46 at the time, took the prescription and had it filled, and got on the internet to see what my options were. I ended up on the Smith & Nephew website, where I was introduced to the BHR option. On that website there was a page to look up nearby OS's who were certified to do resurfacing and, fortunately, there was one nearby. At my first appoinment with Dr. Andy Engh of the Anderson Orthopaedic Clinic in Northern Virginia I scheduled my first surgery. At that time he had done approx. 100 BHR's and I was totally comfortable with and confident in his ability.
Dr. Andy performed a BHR on my left hip 12/18/07. The relief from the pain was immediate: I felt better in the recovery room than I had for long time. Granted, I was on IV pain med's, but from then on, other than swelling and the initial joint instability, which were more a matter of discomfort than pain, I was amazed at how well everything went.
Dr. Andy performed a BHR on my right hip on 4/4/08. I actually looked forward to having the second surgery done, knowing how well things went with the first. Perhaps because I knew what to expect and had been "initiated," the second BHR process seemed even smoother than the first.
Bottom line: If you need to have it done, find an OS who does BHR's that you are comfortable with and do it. Based on my experience, you'll be glad you did.
I'd be happy to speak with you directly, if you'd like. Best of luck.
