Synvisc injections, Glucosamine with Chondrotin supplements, Celebrex, Ice, exercise and maybe biosil supplements, fish oil supplements, Lidocain injections...These are all options. Im a big believer on the Glucosamine but any supplements should come from a Health food store or at GNC..Do not get them at walgreens or Walmart or those places that have a lower grade of it..Also, cortisone injections if severe. If in the Winter, gotta wrap that knee and keep it warm.
