osteoarthritis
"I'm a 41 year old male, been playing volleyball for many years, and had a minor knee injury and went to the orthopedist to get it checked out. He said I had moderate osteoarthritis in both knees and gave me Orthovisc. One injection per week for 3 weeks, not too bad. A little pinch during the injections but no pain afterward. After a few weeks, I noticed a lot less crunching in the knees, and can squat normally again. I believe it has helped a lot, and I hope it continues! I also started taking cod liver oil (with meals) as I read this helps with joint repair and function. They're pretty cheap at any vitamin store. Good luck and I hope this helps someone."
