Silicon knee injections - upside, in six weeks, might be able to walk fairly normally again...

8. My issue is osteoarthritis in both knees. After 20 years in the Navy and 20 in the shipyards.

I also have degenerative arthritis, and a back injury, and was born with moderate scoliosis that was treated between the ages of 6 and 14 by all sorts of stretches and prosthetics that I wore in my shoes until I was 12.

At your age, first thing you need to see is an orthopedist to check your gait and see if you need shoe inserts to even out your gait, or if you need a referral to a skelatal-musculo specialist. I did that when I got out of the active Navy those inserts got me through 20 years in the shipyards.
Next, you should always sleep with a pillow under or between your knees. Your back, hips, and knees will thank you.

Regular low/no impact exercise, and stretches as recommended by your doctor (s).

You shouldn't need the injections unless you have no more cartilage left, or if your ligaments are shot. Preferably when you are closer to retirement age than I am, and not still running after grandchildren you are raising.
