I was diagnosed with protrusion when I was 15 after having hip pain for 2 years, I stopped all running sports (pain improved enormously - only had pain rarely). My hip sockets were protruding and very thin on my xrays/scans but they have not deteriorated as fast as the Dr's/consultants expected - I was told to expect hip replacements in my early 20's. I am 45 now and have been travelling all round the world and very active, hiking up mountains, biking, scuba diving, sailing, swimming, kayaking, snowboarding, sky diving/bungy, waterskiing the list goes on. It is only this last year that I have decided to get my hip replaced as the range of movement has become much more restricted (it is now stopping me from doing lots of the above activities) and level of pain has increased (not in hip but in back and knee!). As the majority seem to be saying have the operation soon, I thought I would share my experience as I chose to delay having the op. I didn't really like football or other running sports so cutting these out of my life wasn't a problem, if it is a major part of your life then probably do the op sooner rather than later. I only decided to have the op when I could not continue to do the things I love!
