osteoarthritis
"About 11 months ago I received the single dose Monovisc. It was painful to receive the shot and the pressure was great as it was injected. It took about 3 weeks for me to feel better. Before the shot I had a high level of constant pain from bone-on-bone on the outer edge of my knee. A pocket of fluid had formed on the outside for weeks and I had been waking up with knee pain during the night for quite some time. This greatly improved my knee pain. It didn't take me to 0 pain but definitely reduced it. 
About 5 weeks ago, I felt the pain creeping up, the fluid forming and began to wake up during the night on occasion. I called the doctor and scheduled the next one, which I'll get in a few days. 
Better than pain or surgery!"
