Total knee replacements have moved on since they first came on the market in the late 60's. That GP is possibly thinking of the bulky replacements inserted so long ago and many did not work, unlike today.
Nowadays there is so much less metal in the knee and on the whole it is an easier and quicker operation. That GP is thinking about the past.
I agree with Jane anaesthesia has also moved on and I was given around 6 choices the first time I had a knee replaced. Last year I was talked into spinal anaesthesia- pain free and I knew nothing about anything.
You need a second opinion fairly swiftly. That GP is in the dark ages.
