I had them done some yrs ago, both a series of SynVisc and yrs later Eufflexa, can't say they did much...I truly truly believe I've gone thru so much more damage from the hip replacement complications I'm left with and subsequent staph infection in knee where they did a "clean out" and I don't think that helped.

Work with rubbing Coconut oil into the knee(s) and also consider Monolaurin internally. There is a LOT of info on this miracle oil.
