Im 55 my mri showed replacment is the only option left as the cartilage is all but gone and osteoarthritis is there. I was shocked considering what I get up to. They recon its so bad if I want to I could head the public list and be next off the trolley anytime I want to. But they have said doing what I do I would wear the new rails out in 5 years or less and they only get two shots at fixing them then you are on your own so they recon try to stretch my time out because they advance the technology every year as well.
Fish oil in volume is a help. I always thought they cut your whole knee out and bang a new metal joint into either bones. This is bullshit ,they remove al the shit that annoys you from within the join then they screw in titanium rails top and bottom either side of either bone so the rails glide on each other.
