osteoarthritis
"My knees were so bad I could barely walk around the office without limping.  I had cortisone shots in both knees, which helped, but the Orthovisc treatment has been remarkable.  A very noticeable improvement: I am much more able to walk, stay on my feet for hours, work in the yard, etc.  As many others have commented, the first injections (one in each knee) were painful and left me limping.  The three remaining injections, however, were painless. I don't know how long the impact will last, but so far, so good.  The only downside is the cost.  I have a high-deductible plan, and I ended up paying over $1,000 for the treatment.  I hope I do not have to do this more than once a year at the most."
