Philosophy of Care

Dr. Meehan believes that the successful journey from an initial patient visit to completed post-operative care involves a team of highly qualified people, from nurses to therapists to surgical technicians. He has helped develop and grow the perioperative home that has led to UC Davis being identified as a top performing hospital for both hip and knee replacement surgery. He enjoys meeting new patients and educating them about their condition and helping them achieve a better quality of life that includes less pain and improved mobility.

Clinical Interests

Dr. Meehan is an orthopedic surgeon with subspecialty training in Adult Reconstructive surgery that includes hip and knee replacement. He has spent over 20 years in an academic practice that treats people with age-related osteoarthritis and also people with the most complex musculoskeletal conditions that are referred to UC Davis Health. He strives to provide the safest possible care that incorporates emerging technologies including computer navigation and modern implant designs.

Research/Academic Interests

Dr. Meehan’s research interests have included surgical outcomes in hip and knee replacement using large databases to identify best practices and also identify risk profiles for potential complications. Recently he has published articles on the hip -spine interaction in hip replacement and the potential for accelerated osteoarthritis in select patients. Currently he is studying a novel blood serummarker for venous thromboembolism and its potential as a less invasive technique for diagnosis of blood clots in post- operative joint replacement patients.
