I am 3 1/2 years post op. your activity is going to depend a lot on you and your overall health. But, when i had mine done, i was in pretty good health. however, there were a lot of things i couldn't do afterwards. i am unable to kneel or get on my knees in any way without pain. i have to bend to pick up or lift things. i had to quit my job - i was a store manager, because i couldn't stand to be on my feet that much. So, i had to go to a sit down job. i tried exercise programs - without luck - i cannot do any type of exercise except walking. i do know someone who golfs and has had knee replacement - but i don't know about the basketball - it might depend on your age. I try to do whatever I can. i still climb ladders - paint rooms - do most work -even move furniture. i have trouble with a lot of stairs and lifting things up and down starirs. I am also having some problems now. i moved the furniture in my office and helped someone move and i am having knee pain in the right knee. i have an appointment on wed to see what is wrong.
