I am 1 yr and half out from TKR. I had an awesome physical therapist did cupping and had immediate relief got a bunch of feeling back in that area too. Still have some permanent numbness that is slightly larger area than I had from a previous meniscus surgery but no issues. also had me use roller on both sides of knee from top to bottom every day for 3 minutes per roll. No pain at all. Once surgeon has done their job physical therapist is lifeline in my experience.
