Knee replacement?

@ray666 Have you tried hyaluronic acid injections in your knee(s)? I've just finished with my 2nd set of injections (3 years apart) (3 injections, each one a week apart of some viscoelastic joint lubricant material). The first set of injections 3 years ago didn't seem to have much of an effect on my knee pain. This year, after arthroscopic surgery on my left knee in April '25, it is working very well in reducing pain. I have a spot on that knee that is bone on bone and contact in that spot is pretty painful. For me, I'm trying to find out 1.) Are the hyaluronic tablets on the market any good for pain relief? and, 2.) if I've been given the lowest grade of viscoelastic HLA and it does some good (I do not know how long it will last before it disappears from the knee joint), what about the other commercially available HLA injectables that supposedly last much longer than the cheap stuff? My ortho knee specialist seems to be familiar with the better ones, but she says Medicare HMO insurance will not cover the cost (I don't care about that cost). I'm still texting her about this issue.
