For so many years I have advised patients NOT to be infected with “any stuff” in the knee, mostly because long-term effects are not known. Steroids may temporarily help but they are “destructive” and nay even causes rupture of ligaments.
Acupuncture is very often quite effective but may have to be repeated. I have taught quite a few families to do home acupuncture which is really easy to perform and not dangerous. No “stuff” is being injected.
