Hi Rhetman - Sounds like you're recovery to this point is going well if you're thinking about sprinting! I had my left hip resurfaced with Dr Peter Brooks of the Cleveland Clinic 6 months ago today. I'm absolutely thrilled with my recovery to this point. I've gotten to the point where I really don't think about my hip anymore. Just feels like a normal hip. Dr Brooks has the most conservative recovery process of any of the surgeons of seen discussed on this forum. I was on a strict 75% weight baring rule for the first 6 weeks. At my 6 week checkup I was released from crutches, and back to everyday tasks however I am restricted from doing anything "high impact" for the balance of the year. No jumping, running, etc. My surgeon provides some pretty limited leg lift exercises that focus on stretching. I'm permitted to do light exercises such as swimming, exercises bike, etc., with very limited resistance. Pre-surgery I was very active, so now that my leg/hip pretty much feel "normal" it's getting harder and harder to stay away from high impact activities, but after all this effort I've gone through the last thing I'm going to do is ignore doctor's orders. My advice is to be patient, and follow your surgeon's recommendations to the last detail.
Good luck in your continued recovery.
