Victor Antonacci, MD

I would like to take this opportunity to tell you more about myself and my experience in health care. As a native-born New Yorker, my wife, children and I moved to Rockford after the September 11th tragedy. I’ve found Rockford to be a restful, family-oriented, and charming city; one in which I have greatly enjoyed serving patients and building my practice over the years.

After completing my surgical residency in New York at St. Luke’s Roosevelt Hospital, I knew that I enjoyed the field of joint replacement. This interest drove me to continue to hone my skills at The New England Baptist Hospital in a specialized training program, or fellowship, in joint replacement surgery.

My interest in joint replacement surgery continues to motivate me. I am currently the only area orthopedic surgeon utilizing computer navigation in knee replacement surgery and I have a special interest in partial knee replacement, a minimally invasive knee surgery that removes only the most damaged areas and entails a smaller incision and faster recovery than traditional total joint replacement. I also hold specialized training to perform the Direct Anterior Total Hip Replacement procedure.  In fact, as of January 2017, I have performed 1500 Direct Anterior Total Hip Replacements.  My on-going career goals are to utilize the latest technology and refine my techniques in order to improve patient safety, satisfaction and surgical outcomes.

I find personal satisfaction recognizing that my patients benefit from surgical advancements that allow them to enjoy and improve their quality of life. I look forward to meeting you and providing that same service!

I would recommend OrthoIllinois. The visit was very good from the receptionist, nurse and doctor.

The care provider delivered what he is known for -- excellent results with a hip replacement procedure. He never gave me reason to doubt his expertise and I am now walking limp free for the first time in over 12 years.
