Please don't think that because you read of the issues here that EVERYONE has problems with their joint replacements. Remember that most people find us whiles searching for answers to their problem, and that is why you see the suffering folks here.
I know that, in my winter community of mostly seniors, there are at least 100 people with one or more replacement joints. Yet I have only known 3 who had major recovery issues, and only one who had an infection after surgery. We are also part of a large community of dancers, and many of us have had hips and/or knees replaced so we can "keep on dancing" - in that group, I am the only one who had a major complication - that was 12 years ago, it got fixed, and I'm still dancing!
We have a fellow here, @heyjoe415, who seems to have the right approach - preparation beforehand, and therapy afterwards. Maybe he will share some words of encouragement.
