ACL repair surgery is something that the orthopedic surgery community is just now beginning to talk about after decades of subscribing to the belief that it isn’t possible. The belief is slowly changing, in large part because of the groundbreaking surgical work of my guest on this episode, Dr. Gregory DiFelice of the Hospital for Special Surgery, Sports Traumatology & Joint Preservation Surgical department. In this conversation we talk about about the approach surgeons have taken in approaching ACL surgery in the past, what he’s done to ask questions that nobody was asking, and how his steps have led to the reintroduction of ACL repair surgery that is proving to be highly successful.
