San Francisco, CA (Feb. 16, 2025) – On Wednesday, February 12, 2025, Dr. Rafael J. Sierra, professor of orthopedic surgery and chair of the Division of Hip and Knee Surgery at the Mayo Clinic, delivered Grand Rounds at Genentech Hall on the UCSF Mission Bay campus. His presentation, titled "Hip Dysplasia: Are We Changing the Natural History with Periacetabular Osteotomy," explored advancements in hip preservation surgery and the evolving impact of periacetabular osteotomy (PAO) on patient outcomes.
“Dr. Sierra’s presentation was a tremendous opportunity for our team,” said Dr. Erik Hansen, chief of adult arthritis and joint replacement at the UCSF Department of Orthopaedic Surgery. “We are incredibly grateful for his insights into hip preservation surgery and the evolving role of periacetabular osteotomy in improving patient outcomes. His work continues to inspire our efforts at UCSF as we strive to advance care and push the boundaries of what’s possible in orthopedic surgery.”
Dr. Sierra, a leading expert in hip and knee arthroplasty, is widely recognized for his research in hip preservation surgery, femoral head osteonecrosis, and the prevention of complications in hip and knee reconstruction. His research includes clinical trials in hip and knee arthroplasty, as well as prospective and retrospective studies in hip preservation surgery and the diagnosis and management of femoral head osteonecrosis.
Dr. Sierra also focuses on preventing complications associated with primary and revision hip arthroplasty. He investigates the biomechanics of periprosthetic fractures, improvements in function with soft tissue procedures for the abductor mechanism, and failure modes of dual-mobility implants.
In addition, Dr. Sierra leads multicenter trials focused on improving perioperative management in knee arthroplasty and advancing treatments for periprosthetic infections, further enhancing the field of joint surgery.
The Department of Orthopaedic Surgery at UCSF is grateful to Dr. Sierra for sharing his expertise and insights during his Grand Rounds presentation, which continues to inspire the department’s ongoing efforts in advancing patient care.
