Christopher Leibold, D.O., is an orthopedic surgeon who focuses on partial and total knee replacements and anterior hip replacement, a surgical approach that may lead to faster recovery and less pain. Dr. Leibold also provides revision hip and knee replacement.

Originally from Mount Vernon, Ohio, Dr. Leibold has always loved learning and working with his hands.

“My values have always been caring for my family and helping others in need,” said Dr. Leibold. “I got interested in orthopedics during one of my shifts in medical school. I learned to love the diverse field of orthopedics and how you can decrease pain while improving the body’s range of motion.”
