All of the activities you mention, should be possible after total knee replacement.
If the X-ray look bad. If your orthopedics recommend surgery. And, most important, if you are restricted too much in what you like to do, I wouldn’t wait too long. The longer you wait the more deconditioned you’ll be. ROM will decrease. Recovery will be quicker and better, if you are still in relatively good shape.
Just some things to consider. As I don’t have much insight your case you should mainly follow your doctors recommendations. But I’ll be happy to answer any further questions.
