Dr. Mark Oyer completed an Adult Reconstruction Hip and Knee Fellowship at the University of Wisconsin Madison School of Medicine and Public Health. During residency, he developed my interest in the orthopedic sub-specialty of total joint replacement. He has special interest in outpatient and minimally invasive surgery, the Direct Anterior Approach for total hip replacement, and complex revision surgery.
