"I had been in pain for over 10 years with my knees and constantly on pain medication. I am a musician - performing for events on keyboard and vocals, standing at the keyboard leading my band. At the end of every performance I was in terrible pain. When I got home each evening I was limping and could not sleep without pain killers."

"I was an ardent yoga practitioner for many years and avid hiker until black ice brought me down. Not in an ashram or on a mountain but right on Fifth Avenue and 13th St. I realized what had happened -- a broken kneecap -- and that I couldn’t get up. I once thought I would never cross the street without crutches again, but now I’m back on the mountain!"
