Researchers recently made an announcement at the American College of Rheumatology's Annual Meeting in San Francisco that's great news for anyone suffering from knee pain. They announced that they were able to demonstrate that injecting ozone gas into the knee can help reduce pain and improve the quality of life of people suffering from osteoarthritis (OA) in their knees. I have to be honest, these findings didn't surprise me at all. That's because I'm very familiar with this technique of injecting oxygen into an inflamed joint. In fact, I invented it over 20 years ago. I call it Prolozone® therapy.
