Also, shower chair is very valuable. To hang one leg out straight at first and then later before you get balance back. It would be awful to fall on new knee. I live in rotten winter weather and got handicap permit asap. Again, don't want to fall. You will be icing a lot! If you can rent or borrow one of the polar ice machines it is just wonderful. Later for occasional use you can use freezable packs. You can get heavy duty ones on Amazon for very reasonable price. I still use daily after exercise at 11 weeks out. I had first knee done in summer and second in October -- the pain and recovery period where totally different for each. I think previous response is generally optimistic for being off walking aids so soon. Every knee is different and my second one has been so much more difficult than the first. You will need to pace yourself depending on your particular recovery experience. Your Dr and PT will also advise you. I would not have even thought of exercising on the floor. My "good" knee was bone on bone during the recovery of the first and now they are both still rehabbing. I could never have gotten back up! Be prepared for a lengthy rehab time frame. If you luck out and it progresses faster that will be wonderful. I was amazed at how different the knees did with same surgeon, same PT, same everything. All the best with your replacement!
