osteoarthritis
"I had a series of 3 injections of orthovisc in both of my knees last year and they worked great!! Pain relief after 3 weeks which lasted 3 full months. Same time of year I decided to get another series of injections, this time they did not do a thing for me. Actually I believe it made it quite worse! It's been over 6 weeks since my last shot, I've still yet to see anything beneficial this time around...."
