I’ve rehabilitated a lot of people after knee replacement. I like to ask what they did leading up to surgery. Not everyone tries those injections or has them suggested. It appears to be more of an option than a mandatory conservative step before replacement surgery.
I’ve had people tell me that they had no benefit, a few days, a few weeks or months. I think the goal is six months. Some made it there and a few upwards of a year. It buys some time and that’s about all it’s meant to do. Experience varies and seems to reach a point where the benefit diminishes with subsequent injections. Again, it seems that the experience is very different and individual.
