osteoarthritis
"I had arthroscopic surgery on my left knee 2 years and 6 mo. ago. My orthopedist told me that I will eventually have to have a total knee.  Since then , I have had 2 Euflexxa injections. I will be receiving another injection in 2 weeks. It has been 15 mo. since the last shot. 
I'm a retired Physical Therapist and do my exercises faithfully."
