Yes, the PT is very important. I think that I would come home instead of rehab the next time because I just like being home and I do have someone to help me. I had one knee done and only took meds for about five days. Needed it for PT, though. Pain meds were messing with my digestive system and I felt better without them. Didn't get the shower chair and high toilet seat that they wanted me to take home. I didn't need it. Use the ugly walker or cane for stability and you will do fine.
