About me

Dr. Erik Hansen is an orthopedic surgeon who specializes in surgeries of the hip and knee, including reconstruction, replacement and revision (surgery to address problems with or caused by a previous implant). He has expertise in the direct anterior approach for hip joint replacement, a minimally invasive approach that has advantages such as faster postoperative healing and enhanced joint stability.

Hansen has been the William R. Murray, MD, Endowed Chair in Orthopaedic Surgery since 2019. In research, he focuses on diagnosing, treating and preventing infections around artificial joints.

Hansen earned his medical degree and completed an orthopedic surgery residency at UCSF. He served as a fellow in adult reconstructive surgery at the Rothman Orthopaedic Institute at Thomas Jefferson University Hospital.

Hansen directs a database of total joint replacements as well as a database of postsurgical joint infections for the surgery.

      I would choose Excellent with anything regarding Dr. Erik Hansen. I appreciate the fact that he reviewed my X-rays, MRI, and PT notes before our first visit and again before the follow up visit. He also showed me the MRI scan area by area which had not been done by the previous doctor. His analysis of my injury, prognosis and outcome was vastly different than the MRI analysis and the previous doctor's prognosis. I believe Dr. Hansen encouraged me and helped me improve my knee to the point of not needing surgery.

      Dr Hansen listened and took the time to answer all my questions. He also worked with scheduling to expedite my surgery based on my current condition
