Hi, I just found your question, I hope it is still valid to reply :)
i am a 23 year old female and I had both my hips replaced at the end of 2004. I had had severe pain in both hips for a long time. It was worse at night, causing me to be unable to sleep.I was on very strong pain killers and they still did nothing to help. I had a lot of people saying it was very young to be having it done, but the thing is if it is so bad it runs your life, then why wait.
By the time that I need replacements the technology will be better again, so who knows what will be available. My surgeon was very helpful, he did lots of x-rays etc to work out how bad my hips really were. It turned out they were both extremely worn away at the joint. He said I could wait, and deal with the pain for a few more years while putting my life on hold, but what do you really gain by doing that?
So I have had it done. Iv had arthritis since I was 4 years old and been on pain killers since then. After the operation pain went away I have not had to take a pain killer since. Im not saying it's easy, it's not. The days following the operation is the hardest part to get thru. Plus you really have to dedicate yourself to doing the physio right. But all im saying is don't discount it because of your age.
If you want to know anything else feel free to ask me :)
hope this helps
