I am a few weeks ahead of you having had surgery 12/8. I finally stopped PT at 7 weeks. I do my exercises and bought a 2 lb weight to help strengthen my quads. I still have down days but feel I have turned a corner and making improvements. By the end of the day I am tired but sleep is better and I walk better. I my case stopping PT was the best option. I took back control of my healing and my body. pt had me in tears and then the following day I hurt more. Hang in there and know we are in this with you to support.
