Did Bears star Brian Urlacher go to Germany for medical treatment or not? It's a question the football player isn't answering, but a Chicago woman who underwent the procedure says it definitely works.
Andrea Hall suffered from osteoarthritis so bad that she couldn't walk to her mailbox, so she traveled to Germany to receive the procedure, called Regenokine.
The procedure is not approved for use in the U.S., which is why athletes such as golfer Fred Couples, baseball's Alex Rodriguez and basketball's Kobe Bryant have flown to Europe to try it out.
The doctors take the patient's own blood and injects it back into their joints, which they believe boosts its healing power.
"I got six shots in my back and one in each knee, and I did the same thing every day for five days," Hall said. "I walked in with a cane and walked out and went shopping."
U.S. doctors say they'd like to see more research on the procedure before advising anyone to try it.
