NOW OFFERING OUTPATIENT TOTAL HIP AND TOTAL KNEE PROCEDURES.  Recover in your own home safely and comfortably!


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!

Here's what my patients are saying:

Dr. Antonacci did an anterior total hip replacement for me on Dec 16, 2015. I had a hip replacement on the other side in 2001 (the "old" way, by another doctor), so I had something for comparison. While the first replacement  trouble free, I remember that recovery as being quite a drawn out process! I'm amazed at how quickly I've been able to recover with this procedure! I think it's wonderful that we have Dr. Antonacci in Rockford, IL!

The staff is very professional and compassionate. Dr. Antonacci and his team have taken excellent care of my hip and knee issues. I had left hip replacement in April 2014 and functioning well in 4 weeks (one night in the hospital and able to walk with little assistance and navigate stairs when I went home).

"Dr. Antonacci operated on my hip in March and one month later I was visiting relatives in South Korea.  I am now pain free for the first time in nearly a decade thanks to Dr. Antonacci's expertise with the anterior total hip replacement procedure."

"Within nine days of my recent total hip replacement, I was walking comfortably without even a cane.  Due to Dr. Antonacci's expertise, I have my life back, no more pain.  Without reservation, I recommend the doctor and his staff."  Anonymous review on
