Medical science has for years contended that the knee’s anterior cruciate ligament does not heal by simply regenerating. That’s the reason generations of NFL players have had surgery to repair ACL injuries.

Miami Dolphins quarterback Ryan Tannehill went another direction, not having surgery but rather choosing to rehabilitate the partially torn ligament and follow that with stem cell treatments. On Thursday, when Tannehill spoke publicly for the first time since the end of the 2016 season, he said his ACL was indeed healed.

“Yeah,” Tannehill said when asked specifically if his ACL had healed, “it’s really strong and ready to go.”
Tannehill discussed the stem cell treatment he underwent which he partially credits for his recovery.

“I did a lot of research and finding options that were available to me and finding what fit,” Tannehill said. “I spent a lot of time researching and talking to people who are familiar with all the different types of treatments. That seemed to be the best fit for the injury that I had.”

“That’s the basic concept. So your blood stream is carrying stem cells to all the injuries you have throughout your body. Your ACL never completely heals because of lack of blood flow and so they’re just artificially becoming the blood stream to carry the stem cells to the location.”
