Hi,
I am a 50yo male, 6'3", weigh 300lbs, have played lots of sport(basketball,tennis,golf,skiing) all my life. One of my hips seems to have taken the toll of me being heavy and active and might need to be replaced. How strong are the artificial hips? I know I need to lose weight for a number of reasons, but am concerned if the artificial hip "wears out" too quickly. How many times can they be replaced? Let's say I get down to 220lbs - still a worry? How much sport will I be able to play in the future?
