I have my name on the list for a knee replacement in 3 months' time. But I can't decide whether to have it done or not. The consultant tells me that 80% of the people who have it done are pleased. 1 in 300 dies of a blood clot, 5 in a hundred get an infection and some feel stiff and uncomfortable ever after. I am in constant discomfort and have to go upstairs on all fours and find it painful to walk but I wonder if the devil you know is better than the devil you don't. Anyone here know anyone who's had such a replacement? Any anecdotal info? After the op one is apparently in pain and immobilised for 6 weeks and is not back to normal (even if one is one of the happy 80%) for 6 months. Any advice?
