Steroid injection for osteoarthritis is very
common.
However, the problem of steroids is that they are very acidic drugs.
Usually, we mix steroids with local anaesthetic, which has a toxic effect to the cartilage
and you may have heard that you can only have the steroid three times and you cannot have it any more.
The pure reason is that this will not work anymore, and if you think about it, we are using a very acidic substance
to put into a joint that is painful, it doesn’t
add up.
So therefore, a better alternative is to provide
the cells with growth factors, to provide
the cells with an environment where they can recover. For example, we can use PRP or hyaluronic acid,
these will help to maintain the joint health 
a lot more than steroids.
