Animal ligaments can repair human knees - ABC 7 News Story on Kevin R. Stone's work on the Z-Lig

Bay Area researchers have developed a new technique to help repair injured knees. It could someday change the way many surgeries are done. 

From bike riding to basketball, it would be hard to find a sport that Marty doesn't like. But the financial manager, who asked us not use his last name, also paid a painful price with his right knee.

"I'd just torn my ACL playing basketball for the second time in that knee. I had a pretty bad experience the first time, I had a patellar tendon graft, very painful, took a long time getting back to being active," he says.

Marty turned to San Francisco surgeon, Kevin Stone, M.D., who says the grafts typically involve harvesting bone and tendon from the front of the knee, to rebuild the ACL.
