Hip dyplasia

Hello
i am new to the site and have a daughter, Rachel, who is 29 and has cerebral palsy. She has significant disabilities but can walk very short distances. She has hip dyplasia and a recent X-ray showed no significant deterioration in the last four years, which is good news, but she does have obvious discomfort on her left side. 

We haven't got to the painkiller stage yet and have been advised not to consider surgery yet as Rachel's learning disability means that she will not co operate with any post surgery exercise or instructions. While she can still walk, I am unwilling to consider it but, while I have met several young people who have had hip surgery, none of them were walkers. I would be interested in hearing experiences or recommendations from anyone in a similar situation.

Thanks so much for reading!
