Hi Jack. I had my surgery (RTKR) on Jan. 6 and went back teaching last Monday. I decided to just teach mornings for the first two weeks and that was a really good decision. I am not teaching Phys. Ed. however (except for one period a week), and that would be more difficult for sure. All the same, I am on my feet most of the time and moving around, going up and down stairs and walking long hallways. I have found that going back to work has been great for the most part. I forget about my knee (except to ice at recess) while I'm teaching and all that movement really keeps my leg limber. I amazed that my walking speed has increased and is getting back to my normal "get there fast" pace. I may tell a different story next week when I'm full-time and I have to do my exercises after a long day and try to get to the gym as well.
Can you possibly start part-time and work up to full-time after you've built up your stamina? Even one or two weeks would help.
The day you describe sounds a little ambitious to jump right into. Is there any way you can hold off on the golf, or get someone to cover for part of the time?
On the other hand, you may be quite fine after the first week and it may help your recovery. Of course, you'll probably be in bed by 8:00 for a bit!
Good luck,
Mag
