I've had injections twice.

At around 50% cartilage loss.

The first time didn't last 6 months.

Went to a different ortho and he asked if I first had a round of cortisone to reduce inflammation and swelling of the joint before the treatments. Negative.

Did a round of cortisone, then a round of the injections and it lasted quite a few years.

Getting to be that time again (and I've got heel spurs now too), but COVID has effed up my plans to get things fixed before summer.
