How did you find out about the "Softwave Technoplogy" ?

Was it from an ortho doctor or a pain managements specialist doctor? Covered by insurance? If not, how much did it cost? Did they say how long the positive effect would last, assuming it was going to work? What was wrong with your knees? Meniscus operation beforehand, ligament inflammation, or??? Was the intention to regenerate meniscus and cartilage?
Thank you so much!
