Dear petow23, I am really sorry to hear that you have moderate OA at the very young age of 35! Any hip replacement procedure is major surgery, look at some of the videos on Youtube of hip resurfacing for example. Also, if you are female then I would have even greater reservations regarding any procedure. In my humble, layman's opinion is that as you have diagnosed 'moderate' OA, I would consider rest and a period of non-weight-bearing activities. Take several months' or even up to a year of this. Return gradually to your sports and gauge how you feel. Also, scientific progress will eventually lead to the 'perfect' hip replacement procedure/bearing surfaces. I have had to go for a resurfacing at the age of nearly 63 however I managed to prolong my severe OA hip for 3 years by running less and by reducing my pace! I am now bone on bone and still run half marathons and do 55 miles at least every week! To finish, I would, if I were in your position, try a year of less intensity with plenty of rest and stopping as soon as pain is felt. A delay would also mean you could save up money for any future procedure. In Scotland, thankfully, we have our wonderful NHS and I go in for my resurfacing op on Wednesday 9th October in Glasgow! All the best for the future, Jim!
