Mr Mark O'Sullivan

Mr Mark O’Sullivan is an Orthopaedic Surgeon and a Chief Investigator on the Victorian hip dysplasia registry (VicHip).

Mark is Melbourne born and completed his basic medical training at Melbourne University. Orthopaedic training was also through the Victorian training program and was completed in 1990.

After completing his basic orthopaedic training, he spent two years in the United States, obtaining a Fellowship in Paediatric Orthopaedic Surgery. On returning home to Melbourne in 1992, he commenced work at the Royal Children’s Hospital and the Western Hospital in Footscray. He has worked at the Royal Children’s Hospital for over 20 years. He is a senior surgeon at the Royal Children’s Hospital. He is particularly involved in the management of hip and knee conditions and the treatment of bone and soft tissue tumours. He has teaching commitments with the registrars, Fellows and medical students that rotate through the hospital.

Mark has always had a strong interest in sporting injuries. His work also encompasses knee and hip surgery in adults and children. Most of this work is performed arthroscopically. He has particular interests in the management of acute knee injuries, including ACL reconstruction, the management of meniscal injuries and patellar realignment surgery. He has been involved in the management of difficult hip conditions for 20 years using a combination of femoral and pelvic osteotomies and, more recently, hip arthroscopy to improve the outlook of these hip problems. Mark has joined with several other surgeons to form a Hip Preservation Group in an effort to manage the more difficult of these hip conditions. The other major area of Mark’s practice is the management of bone and soft tissue tumours.

Mark is a member of the Australian Orthopaedic Association, the Australian Paediatric Orthopaedic Association, and a Fellow of the Royal Australasian College of Surgeons.
