Dr. Karzel has been actively involved in education and research into shoulder problems. He has a particular interest in the treatment of rotator cuff and dislocation injuries in the shoulder, and has helped pioneer several new techniques for the treatment of these problems. One of his inventions, the Transporter Device, is used to perform procedures arthroscopically which previously required open repairs. He has published numerous scientific journal articles and textbook chapters on subjects such as knee ligament reconstruction techniques and arthroscopic shoulder surgery. Dr Karzel has also presented many scientific papers, and is frequently invited to give instructional course lectures at national and international orthopedic meetings. He remains actively involved in several research projects concerning knee and should injuries.
