Thanks Bart. I do believe the FDA has approved PRP injections for the knee. As you point out, insurance coverage is another thing.

I'm on Medicare and that covers some things outside the "normal" (for example, acupuncture or dry needling for only the lower back is approved).

I don't know if you are on Medicare. Medicare might cover PRP injections. May be worth a check.

Otherwise, if you're bone-on-bone, are you considering a TKR? Both of my knees have been replaced and it has been a huge relief to be out of pain. I'm 71 now (knees replaced in 2023) and in the gym everyday - 5x/week spinning for cardio health and 2 days for resistance work with a trainer.

All the best to you Bart!
