I know there is probably a previous discussion or comments about the use of a treadmill during knee replacement recovery but I couldn't find it, so I guess I'll post the question. I have not asked my OS and didn't have PT so I'm asking the group. I don't care to walk outside and prefer a treadmill, but one of my OS consults told me to stay off of the treadmill with a replacement because it puts more stress on the new part more than "regular" walking. Has anyone else been told this? I have a huge expensive treadmill and if I'm supposed to use it, fine, but if I should be using something else, I'd rather sell it and buy something I CAN use. Like everyone else, I'm trying to lose weight and currently ride a stationary bike, do leg lifts, etc.
