Was it the Nuffield in Pltmouth, I had 2 new knees back in 23, Had the same type of anasthetic, Just before the surgeon was about to cut ( I wasnt fully out for the count ) I looks ocer the screen and says remember measure twice cut once, he nodded to anethetist and off I went, great surgeon Simon Coleridge, used to sail with a friend of mine, the second opp I asked to stay awake as I wanted to watch, noooo chance, also asked for the old bits of bone back.... Why ??? well my dog loves chewing bones, all the theatre staff are going yyyukkk. 2 years on from 1st opp and not looking back, 1st 2 weeks were absolute misery though
