We interviewed renown orthopedic surgeon Dr. Nima Mehran to talk all about all things related to the anterior cruciate ligament or ACL. With over 200,000 ACL injuries per year and over half of those injured going to go surgery, the ACL is a hot topic within the performance and health fields alike. But what is the ACL? What does the ACL do? Do you need surgery after an ACL injury? We answered all those questions and more in this fantastic interview!
