  • Background

    J. Todd Lawrence, MD, PhD, is an attending surgeon with the Division of Orthopedic Surgery at The Children's Hospital of Philadelphia and an assistant professor of orthopedic surgery at the Perelman School of Medicine at the University of Pennsylvania.

    Dr. Lawrence obtained his medical training at the University of Pennsylvania, Philadelphia, PA. While there, he also earned a PhD in Cell and Molecular Biology. He completed both his internship in general surgery and residency in orthopedic surgery at the Hospital of the University of Pennsylvania.  

    To continue his training and education, Dr. Lawrence completed a fellowship in pediatric orthopedic surgery at The Children's Hospital of Philadelphia, and later a second specialized fellowship in sports medicine and shoulder surgery at Duke University Hospital, Durham, NC. At Duke, Dr. Lawrence cared for two NCAA tournament championship teams including the NCAA Men’s Basketball Championship team.

    Dr. Lawrence has a highly specialized skill set and is dedicated to the care of high-level pediatric and adolescent athletes. He has particular expertise in the arthroscopic treatment of injuries to the knee, shoulder, elbow and ankle. He helped develop a new technique of reconstructing the anterior cruciate ligament (ACL) in patients — who are still growing and developing — that does not disturb the patient's growth plates.

    Dr. Lawrence's research interests center around determining the optimal treatment strategies for a number of sports-related injuries in children. With his background in basic science research, he has also conceived of a novel cartilage repair strategy for adolescents and is working to translate that to clinical practice.
