I had my TKR December 1., had my follow up with with my orthopedic surgeon this week. My foot and knee swells over day as well, if I am on my feet most of the day, my knee is warm and stiff between . He told me to continue exercising, I ice between, leg high. The inflammation can stay for up to six months. I do water aerobics and Chair yoga again to stay fluid and continue to take Celecoxib 200 mg for another 2 weeks.
