I had total knee replacement, manual manipulation and revision surgery within 10 months. I can bend my knee 95. But it swells up after physical therapy and/or exercise. I can only walk 1/2 mile. Started electro magnetic therapy and it is helping with the scar tissue build up but still having swelling. I even rented a flexinator for home. No pain unless I bend my knee to far. I'm also seeing a functional doctor helping me with walking/sitting. She even prescribed Epsom salts for feet and knee. And magnesium for pain/stiffness. It's hard not to be depressed. It doesn't make sense to exercise with my knee swollen. Did I mention I was also given steroids? Any more suggestions? I was wondering if anyone has tried stemwave Therapy. It's costly, does it work? Will nano knee help? Go through the process again? Any suggestions?
