In reply to The Reaper:
Hi there...have just arrived back from a trip to Scotland and picked up this thread. I had bi-laternal total hip replacements in April 2004 at the age of 56. I went in to have them both resurfaced but they were just too bad for that option so woke up with the second option...!!! My first words to my surgeon when he told me were "will I climb again?" his reply "of course you will". He was right - I worked hard on my rehab and my first climb after the op was in July 2004 in Pembroke. I have gone on from strength to strength with much greater flexibility than I had been experiencing for several years. I climb with my husband at every opportunity both here and abroad. We have just been in Scotland climbing ice gullies this past week.
I think there is an important issue worth discussing with your consultant and that is the type of prosthetic that will be used. When I knew I had to have both my hips replaced I sought out a surgeon who specialised in orthopaedic surgery for younger active people who want to continue with their sport. I have had two metal on metal larger diameter head replacements which means that there is an absolute minimal chance of dislocation. I had them both done at the same time as I wanted to get back climbing as soon as possible.
Another important aspect is rehab. You will get some NHS physio but in my experience this was insufficient for someone who wanted to continue with an active and demanding sport. What made a great difference to me was having regular physio and regular sports massage.
Good luck and I hope it all goes well for you.
