Kristaps J. Keggi, MD, Dr Med (hc) is the Elihu Professor of Orthopaedics and Rehabilitation at the Yale University School of Medicine in New Haven, Connecticut. Dr. Keggi was born in Latvia and arrived in America as a World War II refugee at the age of 15 years. With the exception of 2 years of general surgical training at the "Old" Roosevelt Hospital in New York City and 2 years of military service with the United States Army in Texas and Vietnam (3rd Surgical Hospital, Army, Mobile), Dr. Keggi has been associated with Yale College and Yale University since 1951. First, he attended Yale as an undergraduate and medical student, later trained as a Yale orthopedic resident, and ultimately joined the teaching faculty of the university, a post he holds to the present day.

Dr. Keggi completed his orthopedic training in 1964 and was practicing and teaching orthopedic surgery for more than 5 years when the Charnley Low Friction Arthroplasty was brought to the United States. He was among the first in Connecticut to perform this procedure in its classical transtrochanteric manner. Based on his training with Wayne O. Southwick, MD, who encouraged innovative thinking, he rapidly moved to utilize the less traumatic Direct Anterior Approach. With the help of Terry Light, MD, his resident at the time, he presented the DAA technique for total hip arthroplasty (THA) and published his early results as a Scientific Exhibit at the 1977 Meeting of the AAOS in Las Vegas. Subsequently, in October of 1980, he published the results in Clinical Orthopaedics and Related Research, thereby becoming one of the first American surgeons to publish on the DAA for THA. Continuously since that era, the DAA has been his primary approach for all simple and complex hip arthroplasty procedures.

Over the course of a career spanning over 50 years, Dr. Keggi has improved the lives of thousands of patients, has taught over 150 Yale residents, and has hosted more than 250 international fellows brought to Yale and The Waterbury Hospital from Latvia, Estonia, Lithuania, Russia, Ukraine, Georgia, Belarus, Kazakhstan, Uzbekistan, Tajikistan, Sweden, Germany, and Vietnam. He is the author of numerous publications on total hip surgery, has lectured at multiple meetings and locations, and has visited sites around the world to teach and perform DAA hip replacements.

During his career, Dr. Keggi has received numerous Yale teaching awards, honorary degrees from Universities around the world, and has been honored with the Latvian Order of the Three Stars in 1993, the V Class Order of the Estonian Red Cross in 1999, the Distinguished Service Medal of the Latvian Physicians Association (the second ever awarded) in 2009, and the Silver Medal of Medical Dignity and Service to Russian Medicine in 2012. He was granted honorary memberships in both the Latvian Academy of Science in 1990 and the Russian Academy of Science in 1993. One of his greatest honors was to have received the George H.W. Bush Lifetime of Leadership Award from his alma mater, Yale University, in 2005.

Reviews

"This is the single best reference for the direct anterior surgical approach to the hip. The final section of the book is particularly impressive as it deals with outcomes and evolving implant design concepts specific to the DAA. It is an essential addition to the academic orthopedic surgical library."
