I have a torn meniscus in my right knee. So I know how a knee can bring you down. The best thing that I've tried is green lipped muscle. I work in the veterinary field and we use it for dogs with arthritis. They have a human version for it. I'm sure you could look around and find some brands but the one I use is called glycoflex. Awesome really no pain and crepitus in knee is almost gone. Felt fast results. Hope this helps.
