I did cortisone in each knee approximately every 4 to 6 months for many years. I asked for it when the pain level told me I needed it. Was the miracle cure for me for a long time.
But then I had a painful time of it walking around cities in Spain and Portugal in fall 2016 even with cortisone right before the trip; came home and got more cortisone around Nov 2016 that got me through that winter. Probably should have done the surgery then instead, but I was a baby and scared about it, so continued on without.
When I planned a trip to Warsaw, Krakow, and Prague in June 2017, a year ago, I waited with the next round of cortisone, even though my knees were hurting, getting it right before departure, in May. And boo hoo

that's when I found out it did nothing by that point and I had an extremely painful time of it, walking those cities. Big mistake.
Came home and immediately reported that agony; was invited to come in for yet another round of cortisone, only about a month after the May shots, late June 2017. And that round of shots did nothing either. So then I was offered and accepted Synvisc, three weekly shots in both knees and that did nothing either. Still in great pain. That's when I was convinced I was going to have to get a grip and schedule the surgery. Except then I had an unexpected adventure with pulmonary embolisms in July 2017 that put me in ICU for three days and then on anticoagulant for six months, and so surgery was not allowed until that was all cleared up. Which it was, in early 2018, and I got my hematologist's okay to go ahead with my first TKR, which happened in March this year. And while it wasn't easy, it wasn't as bad as I feared it would be.
If there's a lesson to be learned, I suppose it's don't wait too long, as I did, living in agony before you go ahead with the joint replacement surgery! In hindsight I probably should have had my surgery in winter or spring 2016/2017, or even before the fall 2016 trip, and instead it didn't happen until March 2018. Because I was scared.
I have heard that relying on cortisone injections can actually hasten the degeneration of the joint. But I did it anyway because I was so frightened of having the surgery.
