TimoTHY l. Tan, MD

 Timothy Tan MD is a board certified and fellowship-trained orthopaedic surgeon who specializes in adult reconstruction of the hip and knee including both primary and revision surgery. He cares for patients with all types of degenerative hip and knee conditions, as well as those with complications from prior joint replacement surgery.


He attended University of California Los Angeles and graduated Summa Cum Laude in Physiology with honors. He continued at UCLA for medical school and went to the Rothman Institute at Thomas Jefferson University in Philadelphia for his orthopaedic residency. He completed additional subspecialty fellowship training in total joint replacement and adult reconstruction at University of California San Francisco. 


In addition to his clinical activities, Dr. Tan is active in research and has published over 120 peer reviewed papers and his research has been presented at over 300 national and international orthopaedic meetings. He has received numerous awards from the Hip Society, Knee Society and American Academy of Hip and Knee Surgeons for research on outpatient total joint replacement, infection prevention and treatment, and the prevention of complications during joint replacement. He also serves as a manuscript reviewer for several orthopaedic journals. His academic interests include same day joint replacement, and complications and failures after joint replacement. He enjoys talking to and educating his patients about their conditions and the scientific literature behind about their different options and including them in their treatment decisions. 


Tim was born and raised in Northern California. In his spare time, he enjoys playing basketball, tennis, hiking, traveling, and trying restaurants with his wife and Dooly, his dog. He chose to reside in the Central Valley because he immediately fell in love with the community.
