I had a knee replacement 19 years ago due to an athletic career that ended a few years too late. On Thanksgiving I got an infection in it and had to have an antibiotic spacer installed until infection cleared. I still haven’t had the final replacement yet but knowing yours isn’t as bad as it could be may make you feel a bit better. I had to quit playing a week after surgery but maintained. I’ll be looking at another week or 2 at least when I get the final replacement. Having the trumpet to practice during all this is a gift.

Good luck, BTW why do you want to take up something as expensive and frustrating as golf, try pool. Trumpet fulfills all my frustration needs.
