I had good results with hyaluronic acid for knee osteoarthritis. Sometimes they sell it as Type II Collagen. "Source Naturals Hyaluronic Joint Complex" was the best for my relatives/friends' knee problems. I take it a few times a month (with resveratrol) for smooth skin. I have been taking it since 2008 without any negative result.

How does Type II Collagen work for patella tendonitis? I have jumpers knee (chronic) and would love to find something that helps -- even a little.

Seems like it should work. I do not have experience with that condition. A quick search online (patella tendonitis hyaluronic acid) yielded this study: https://pubmed.ncbi.nlm.nih.gov/22526713/

So they are using hyaluronic acid injections for patella tendonitis. Taking hyaluronic acid orally would probably take longer for effects compared to injections. Most people would prefer the injections because they feel safer for a doctor to do all the work. I prefer the tablets. If you have the money, I guess go for the injections. I would use the H.A. tablets. (With a tall glass of water, and do not take at the same time as blood-thinning medication, like pain killers or drugs.)
