hi again Pat, i got an e-mail from dr bose, i'm impressed, thanks again, he did say it is imperative that i keep bone stock and not get a thr because of my age, he wants details of my condition an xray etc, he did also say that thr are more for 70 yea old people and that when young people get a thr there is a higher risk of failures due to high acticity, so being said i am going to get a second opinion and if all else fails i will do my bst to meet with dr bose. I just didn't like when my doctor said that he felt that a thr would be better than a resurfacing, he did say that i could play hockey again and go back without restrictions, but due to this life changing experience i think a second opinion is important,i'm not a guinea pig, i won't go down without a fight.tahnks again for dr bose's email address, he is a very positve dr and seems to care about my situation and very importantly, my age!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
