Thank you everyone. My mum had a hip op. 8 years ago & desided that excerise was out of the question due to having had a back op which had left her partially disabled, so when when she does anything (not very often) out it pops, 6th time end of last year.
This has made me very apprehensive about the op. but know I am a lot more active than she has ever been so was just looking for reasurance as to the success rate & I really need to relieve the pain which pain meds are not doing.
