 Hiking, weightlifting were being significantly impacted by this sharp pain in my knees. So Ryan chose stem cell therapy with Dr. Mark Wagner, MD, at Seattle Sports and Regenerative Medicine. And now... I take my hips below my knees with no pain whatsoever. They feel strong. They feel stable. Which means, yes, he's back to weightlifting. I feel like I have brand new knees. Brand new knees. It's an incredible transition from where it was to where it is now.
