My elderly father's orthopedic surgeon referred me to San Diego Stem Cell for possible treatment for dad's osteoarthritic knees. At SD stem, dad received stem cells injections in low back, one knee, and via IV (as possible support for Parkinsons); he also received an enhanced form of PRP that included some IRAP in one knee. I can't say enough about how wonderful the SDstem staff was: PA Patrick was extremely informative and helpful about explaining the procedures and options, as well as being candid and realistic about prospects for improvement in one of dad's knees which is bone-on-bone.
