Replying to Arthrosurface Procedure

Just wondering if anyone has had one of this procedure.  My mom is looking into getting it since she's skied her knees out and can barely ski anymore without excruciating pain. It's a pretty new procedure but I figured with a site full of other skiiers like this, someone is bound to have at least some knowledge/experience with it. 


I know ski gabber is a shit-show now but hopefully I can get some real information here other than your mom jokes.  If you're gunna make a joke, at least keep it original.

Any help is much appreciated.
