Chapel from Brazil has always been active in sports and a workout fanatic. In 2010, a wear on his left knee had instigated the condition of ACL. Chapel has referred an orthopedic surgeon, who confirmed the diagnosis and suggested surgical intervention. He had a complete ACL and meniscus tear. Stem cell treatment at Viezec saved him from getting operation and arthritis. He feels like he never had the ACL torn. He says “I can bend my knees now and feel that I can do any kind of movement of workout with my legs. I have to say that I have been most awe-struck by your overall professional methodology and the advantage that I have gotten from the stem cell inoculation in my knee and also my shoulder.”
