Theodore J. Ganley, MD, is Director of the Sports Medicine and Performance Center and an Attending Orthopaedic Surgeon at Children’s Hospital of Philadelphia (CHOP). He is also an Associate Professor of Orthopaedic Surgery at the Perelman School of Medicine at the University of Pennsylvania. Since 1997, Dr. Ganley has treated children, adolescents and young adults who are high-level performance athletes at CHOP. He is one of a small group of surgeons in the country with a primary focus on sports and trauma in the young athlete. Dr. Ganley earned his medical degree from Hahnemann/Drexel University School of Medicine, Philadelphia, PA. He completed an internship at Orlando Regional Medical Center, Orlando, FL, and his residency at Hamot Medical Center/Shriner's Hospital for Children, Erie, PA. In addition, Dr. Ganley completed two specialized fellowships: a pediatric orthopaedic fellowship at CHOP, and a sports medicine fellowship — caring for children and adults — at Graduate Hospital, in affiliation with The University of Pennsylvania, Philadelphia, PA. Because of Dr. Ganley’s specialized training and skills to optimize treatment outcomes for younger elite athletes, he was one of the driving forces behind creating CHOP’s Sports Medicine and Performance Center. Dr. Ganley has specific expertise in the arthroscopic treatment of knee, shoulder and elbow injuries. He developed — and was the first in the nation to perform — a new technique of reconstructing the anterior cruciate ligament (ACL) in patients who are still growing that does not disrupt the growth plates. In addition to his clinical practice, Dr. Ganley is also an active researcher. His research interests are focused on the optimal treatment of sports injuries in elite adolescent and pediatric athletes. He has published extensively on pediatric ligament and cartilage conditions in children. Dr. Ganley is co-founder of the Research in Osteochondritis Dissecans of the Knee (ROCK) group, a multicenter/multinational group dedicated to developing superior treatment strategies for cartilage lesions. He helped form the Pediatric Research in Sports Medicine (PRISM) Group and is in the presidential line of that organization. He is also a member of the Multicenter ACL Revision Study (MARS) group, and has studied and published on systematic reviews and meta-analysis of pediatric ACL injuries and associated tibial spine fractures. Dr. Ganley lectures nationally and internationally on ACL reconstruction, OCD lesions, sports and trauma in the young athlete. He is a member of the Pediatric Orthopedic Society of North America Education Committee, and a board member of the International Pediatric Orthopaedic Symposium advisory.
