Orthopaedic Surgery Research

The Department of Orthopaedic Surgery at Royal Prince Alfred Hospital is founded on the idea of academic and surgical excellence in musculoskeletal injuries and conditions. Our surgeons have a diverse range of interests and specialise in multiple areas including joint reconstruction/replacement (arthroplasty), trauma and oncology. Committed to an evidence-based approach to patient education and appropriate care, the department strives to further the field through high quality research.
