Orthovisc
"I had meniscus tears in both knees almost 20 years ago. I've had knee pain ever since. I had the series of injections about two months ago and my knees felt great for about five weeks. I don't know if it's wearing thin or what, but now I've got more pain than I ever had before the injections and the pain is nearly 24/7. Makes me feel like there's some kind of scam involved, like they know that when it wears off it will be worse due to getting used to less pain for a short time. I do NOT recommend it."
