Great news, Marg. I'm happy for you. Just don't try to rush the recovery. Let it heal properly, and all should be well.
I've had 2 knee surgeries in the last 3 years, and before those a shoulder surgery and even a brain surgery. That one was 29 years ago, and I'm doing better than expected for a 59 year old.
So all the best, relax and all will be great.
