I would look in to a regenerative medicine doctor. They will probably recommend PRP first and if that doesn’t work, the new next step is.MFAT WHERE THEY LIPOSUCTION FAT AND INJECT THAT INTO THE AFFECTED JOINT. I AM 71 AND I AM TRYING TO AVOID KNEE REPLACEMENTS. THE PRP HELPED MY RIGHT KNEE BUT NOT MY LEFT KNEE BECAUSE IT WAS BONE ON BONE THE MFAT did help my left knee. I had it done a year ago and just recently had a hydraulic acid injection done so it’s not perfect but it’s definitely better. I play pickle ball so I do not want a knee replacement. Good luck one bad thing this is all out-of-pocket insurance doesn’t cover regenerative medicine.
