In 2002, Canadian Pro Skier Rick Lewon had his right ACL reconstructed by Dr. Kevin Stone, using a Z-lig replacement device a natural alternative tissue engineered from porcine tissue.. Dr. Stone's treatment was a medical breakthrough and the first non-human biologic method for ACL reconstruction of the knee. After this surgery, Lewon went on to win numerous Canadian Downhill Masters titles. 11 years later, his Xenograft is still going strong and is doing a lot better than the ACL reconstruction he had done on his left leg, which used his own hamstring. Lewon says he is hoping to one day get the Z-lig on on that knee too.
