Dr. Darren Herzog is a board certified, fellowship trained orthopedic surgeon specializing in total joint replacement of the hip and knee, complex joint revisions, reconstructions and minimally invasive direct anterior approach total hip replacement surgery.  His clinical focus is on the diagnosis and treatment of disorders involving the hip and knee which often first respond to non-surgical treatments. Dr. Herzog has specialized training in advanced hip and knee replacement surgery otherwise known as arthroplasty.  He has performed thousands of total hip and knee arthroplasties and has extensive experience with direct anterior approach hip arthroplasty, which enable his patients to quickly mobilize only hours after surgery.
