His post-graduate training included an internship at NYU Medical Center and an orthopedic surgery residency at The Hospital for Joint Diseases – Orthopaedic Institute, where he was chosen to serve as an executive chief resident in his final year. Dr. Petraco also completed a research fellowship in biomaterials and biomechanics at The Hospital for Joint Diseases. He is a fellow of the American Academy of Orthopaedic Surgeons and is board certified by the American Board of Orthopaedic Surgery. Dr. Petraco specializes in joint replacement surgery of the hip and knee. He prides himself on offering the latest advanced techniques in joint replacement surgery including mini-incision hip and knee replacement. As director of the Department of Orthopedics at St. Charles Hospital, Dr. Petraco was instrumental in bringing MAKOplasty® robotic partial knee resurfacing to the hospital. This minimally invasive approach, combined with a patient specific surgical plan allows more accurate implant placement resulting in a more natural feeling knee compared with total knee replacement. Patients are typically discharged home from the hospital the same day of surgery.
