Arthritis in knee

I’ve used a support when I’ve twisted my knee and been unable to walk without it. It did help support the knee but not sure how good it would be for arthritis.

For arthritis I use Felexiseq. It’s a gel you apply either side of and ar the back of your knees, leave on for 10 minutes and it gets absorbed to lubricate the joints. I had very creaky knees and could hardly get up out of a chair. After a couple of weeks I found I was mobile again.
