That is SO MOST EXCELLENT !!!
Orthopedic MDs today never really fix anything in the knees, hips or back/neck only remove things (disc, meniscus, ligaments and install auto parts) but very seldom other than set broken bones repair anything. FACT!

Check your state to see if there is a practitioner.
I wouldn't use any other stem cell or PRP treatment . Too many scammer MDs out there
