if understand your question you are worried about the shelf life of the procedure vs current activity. Not sure you would qualify, but if you do not sure why you would wait. Once I was off the meds before surgery, pain was excruciating in right knee. Did surgery in late 2005 and am delighted.

in 2008 moved to Florida and began biking. On road bike for two years now and have done 7,000 miles in those two years. Average close to 40 miles per trip and have lost 45 pounds since mid 2008. On, and did 70 miles this past Sunday after exceeding 68, my age for first time.

So for me no problems with biking and can do many other things didn't do before, like walking eand traveling.

Everyone is different so YMMV. If you can do most functions again you may not qualify. None of your activities seem to be be super strenuous that a TKR would stop them. Skiing, running, jumping etc are frowned upon. Check the literature.

If you do surgery, definitely work out before to keep legs strong.
