About Dr. Sassoon

Dr. Adam Sassoon is board ceritifed by the American Association of Orthopaedic Surgeons and dual-fellowship trained orthopedic surgeon with expertise in joint preservation, joint replacement, and orthopedic trauma.  Dr. Sassoon currently focuses his clinical efforts on revision and primary total joint replacement of the hip and knee, partial joint replacement, hip resurfacing, hip arthroscopy, hip preservation procedures (periacetabular osteotomies and surgical dislocations), and post-traumatic reconstruction. 

Dr. Sassoon completed his orthopedic surgery residency at the Mayo Clinic in Rochester, MN.  While in residency, he also completed a Master’s Degree in Biomedical Science based on work focusing on tissue engineering using adult derived stem cells.  He was given the H.A. Peterson Award for scholarly writing, and was a finalist for the Patrick J. Kelly Research Award for works completed during this time.  Additionally, he was the first individual to be awarded three separate Mayo International Health Program Grants for orthopedic outreach in Central America performed while in residency. 

Following residency, Dr. Sassoon completed an orthopedic traumatology fellowship at Orlando Regional Medical Center and a subsequent fellowship in hip and knee preservation, resurfacing, and replacement at Washington University in St. Louis.  During these two years, Dr. Sassoon performed and assisted in over 1500 surgeries. 

In addition to time spent caring for his patients, Dr. Sassoon has also devoted himself to advancing the field of orthopedic surgery and has contributed over 20 original, peer-reviewed, scientific articles to the medical literature, and authored multiple book chapters in orthopedic surgical texts.  His research has also been showcased in regional and national orthopedic scientific meetings on over 40 occasions. 

Dr. Sassoon is a member of the American Academy of Orthopedic Surgeons, American Association of Hip and Knee Surgeons, Orthopedic Trauma Association, Orthopedic Research Society, International Congress for Joint Reconstruction, Mid-America Orthopedic Association, Alpha Omega Alpha, and Phi Beta Kappa. 

Patient Care Philosophy

"The best interest of the patient is the only interest to be considered," a quote from William J. Mayo is one that has resonated with Dr. Sassoon since he began his training.  Dr. Sassoon treats each patient with respect to their individual needs and goals in an attempt to maximize their outcomes from a biological, psychological, and social standpoint. Dr. Sassoon takes great pride in directing the efforts of a multidisciplinary team in the restoration of patient comfort, mobility, and independence, so his patients can get back to enjoying their lives, families, and friends.
