Clinical Interests

Dr. Gupta is a board certified orthopaedic surgeon with sub-specialty training and expertise in shoulder, elbow, and hand surgery. His practice primarily focuses on shoulder surgery and complex reconstructive surgery. As one of only two active members of the prestigious American Shoulder and Elbow Society practicing in Orange County, he has a particular interest in shoulder replacement and minimally invasive/arthroscopic shoulder surgery. Other areas of focus include treatment of fractures, degenerative conditions, compressive neuropathies, distal radius malunions, and brachial plexus injuries.

Research Interests

Dr. Gupta's research interest includes both clinical and basic science. He has published studies on topics ranging from rotator cuff injuries to distal radius fractures. He is internationally recognized as leader in understanding and treating peripheral nerve and brachial plexus injuries and Surgical Simulation to help educate the next generation of surgeons. He is the Principal Investigator for the UC Irvine Peripheral Nerve Research Lab that has been funded with extramural grants for the National Institute of Health since 2000. This lab is focused on understanding nerve regeneration and Schwann cell control of neural injury.

Background

Dr. Gupta received his undergraduate degree from Rensselaer Polytechnic Institute, and his medical doctorate degree from Albany Medical College through the Accelerated Six Year Biomedical Program. He completed a general surgery internship, residency in Orthopaedic Surgery, and an NIH Post Doctoral Research Fellowship at the University of Pennsylvania. Subsequently, Dr. Gupta completed fellowship training in hand surgery/microsurgery at the University of California, Los Angeles, followed by an AO Fellowship in hand surgery/traumatology/shoulder at the University of Berne in Switzerland. He served in the role of Department Chairman for the University of California, Irvine from 2006 to the end of 2015. During his tenure as Chairman, the department rose from being ranked #128 by U.S. News & World Report to #40 and became the highest ranked specialty for UC Irvine Health.

Dr. Gupta is Professor of Orthopaedic Surgery, Anatomy & Neurobiology, and Biomedical Engineering. He has a very robust surgical practice- both at the University of California Medical Center in Orange and the Long Beach Veterans Hospital. He enjoys seeing patients with routine orthopaedic problems as well as tackling the most challenging clinical cases.
