Can any substance be put in between bones to keep from rubbing togethe

I was told that I had enough cortisone injections in one year.
How many shots can a person get without getting another problem? What else can be used to eliminate pain?

Hyaluronic injections work for some. A rheumatologist can do this for you.

THANK U🤗 I am going to try this! I appreciate your suggestion 🤞🏻🙏

Had cortisone, gel shots hylagen and supratz plus stem cells. Ortho said let’s do a laparoscopic, ok. Had that then year later, TKR. Everything went down hill. That’s over 2 years ago. Not a revision candidate. It’s small amount of med all day. Tried CBD oil. Yuk. I so try to get to the gym. Have tachycardia, not heart meds. Turned my life to poop! Keep icing, elevate and try some of the sleeves for the knee. I see people in the gym trying to avoid surgery.

I need both knees replaced, and I use DMSO in a spray bottle. It is a anti-inflammatory it seems to help. I also have neuropathy and I spray it on my feet as well.

What is DMSO?
Thank you

Perhaps the same medications they inject in knee's and shoulders. Steroids, EU Flex, and I am not sure about geniculate injections. I think those are Radio Frequency Ablations. My mom had a steroid injection that worked great a few months after her replacement. I wonder why your doctor didn't review options to try before surgery. Get it replaced before you get too old. I had it done when I was 62. Again at 65. Bad job the first time. I think they must have been in a hurry. Be sure to read the reviews about where you are going. Lots of bad doctors in a hurry for money.
