I have to agree with Lee about floor care, regardless of how you feel post op. The bottom line is you have a degenerative problem and it could continue at different levels. Floor care will always be risky regardless of the weight of the item. It is about the nature of the movement as well as the weight. Try to permanently move your pots and pans up to a waist high level. I keep my two most frequently used skillets and pots neatly stacked on the stove top. I use cast iron but would do the same if I used lighter weight cookware. Loading and unloading a dishwasher causes me pain. You will get the knack of doing light housework and picking up with a grabber. I would recomend cleaning and moving defensively on an ongoing basis. The doctor and/ or physical therapist will give you all sorts of activities to keep you in shape. Best wishes.
