No experience with giant breeds I'm afraid, but my old GSD girl, who weighed in at around 42k had both her hips replaced and never looked back :D Best money ever spent, and even post operative care was relatively easy. Why don't you ring an orthopaedic practice, your vet can refer you, so that you can ask questions (I presume a hip replacement has been suggested by your vet?) Generally speaking you will be referred for an assessment for hip replacement and you can ask a million questions then (I know I did!) If you haven't been referred, and your practice is suggesting doing the surgery themselves, please don't - insist on a specialist.
Our surgeon was Gary Clayton-Jones, based in Tenterden in Kent. My hero! It may also be that you can be put on to someone whose dog has had it done, my vet has asked me to speak to a couple of people about different experiences that I have had, and I've been more than happy too. Whilst a surgeon etc can tell you all the technical jargon, it's still very scary, and I would have loved to have talked to someone who had experienced it first hand, although every dog is different.
Any questions you think I could help with, I'dbe happy to answer
