Brian A. Klatt, MD graduated from the University of Pittsburgh School of Medicine in 1997. After completing his orthopedic residency at the University of Pittsburgh, he served 4 years on active duty with the United States Air Force. The final 2 years in the military were spent working with the residency program at Wilford Hall Medical Center, and it was there that his commitment to education was solidified. After an honorable discharge from the military, Dr. Klatt completed a fellowship in adult reconstruction at the Rothman Institute, Thomas Jefferson University in Philadelphia. His decision to attend a fellowship at the Rothman Institute was a direct result of meeting Dr. Rothman at a lecture in San Antonio. Dr. Klatt has been lucky to be mentored by many of the great names in orthopedic surgery today. He is currently an Assistant Professor of Orthopedic Surgery at the University of Pittsburgh. Dr. Klatt returned to the University of Pittsburgh, where he continues to dedicate himself to the education of medical students and residents. His research interests are varied and encompass both clinical and basic science topics. He is honored to have worked with Dr. Parvizi to produce this text. This text is their second collaborative effort. Dr. Klatt hopes that it will provide a quick and easy source for residents who seek to understand the essential information required to master total hip arthroplasty.
