Orthopaedic Surgeon
Dr Sam Martin is an innovative and careful Orthopaedic surgeon. He is focused on providing the most up-to-date techniques and technology in hip and knee surgery to the people of regional NSW. He takes meticulous care from start to finish to minimise the risk of problems.
Communication is very important to Dr Martin. He listens to people and doesn’t start by assuming everyone wants or needs an operation. It is very important to him to take time to go through the concerns a patient or their family may have, and to thoroughly answer any of their questions.
Dr Martin does his best to avoid confusing medical jargon. It is important to him that you end up making the decision that is right for you.
To stay up to date, Dr Martin is interested in research and reads and travels widely. He is in touch with world experts and makes sure his practise is evidence-based. The National Joint Replacement Registry is an example of an important resource Dr Martin makes extensive use of in his work.
Dr Martin cares about his patients and is aware that surgery hurts! Minimising the pain involved in surgery is important to him. He strongly believes you should not need to have a very high pain tolerance to be able to rehabilitate well from a joint replacement. He uses the anterior approach with computer navigation for hip replacement surgery and subvastus approach with a lateral incision with computer navigation for total knee replacement. He is constantly refining his practise to improve both early and long-term results.
Dr Martin’s practice is expanding: some patients currently travel from quite a distance to see him. Everyone is welcome! Surgeon visits to observe his techniques are also welcome.
Dr Martin studied Medicine at the University of Tasmania where he graduated with Honours in the year 2000. He trained in Orthopaedic Surgery in Queensland and was awarded a Fellowship of the Royal Australasian College of Surgeons (FRACS) in January 2010. He spent the rest of 2010 and early 2011 in Europe undertaking further Fellowship training in hip and knee surgery. In May 2011 he began his position at the Grafton Base Hospital and has enjoyed working there ever since.
Dr Martin operates at Baringa Private Hospital where he predominantly does hip and knee replacements.
Dr Martin is committed to the Clarence Valley region. He consults in Grafton, Maclean, Coffs Harbour and Woolgoolga. He is currently working on the development of a specialist centre and private hospital adjacent to the Grafton Base Hospital.
Orthopaedic Surgeon
Dr. Daniel Cohen is an Australian trained specialist hip, knee and trauma Orthopaedic Surgeon who believes in a patient centered, personalized approach drawing on both traditional and innovative surgical techniques.
Dr. Cohen graduated from Sydney University Medical School in 2010 and was subsequently offered a position on the NSW Orthopaedic Training Program. He completed the Royal Australasian College of Surgeons Orthopaedic Training Program in 2020. Dr. Cohen then undertook postgraduate subspecialty training both locally and internationally. This included a fellowship in hip and knee replacement at the prestigious St. Michael’s Hospital, University of Toronto Canada. This subspecialty training enabled him to further refine his skills in highly complex hip and knee replacement procedures. He is fellowship trained in multiple approaches to hip replacement including the minimally invasive anterior approach and the direct superior approach.
Dr. Cohen has also completed a robotic hip and knee joint replacement fellowship where he learned about patient specific planning and component placement based on individual patient anatomy.
Beyond his clinical work, Dr. Cohen has a strong interest in research and has previously completed a research based Masters of Science in Physiology. He has numerous publications in peer reviewed medical journals also presenting his research nationally and internationally. His research interests include alignment and balancing in knee replacement, day surgery joint replacement and recently the timing of surgery during the COVID-19 pandemic. Dr Cohen has also been involved in quality improvement projects aimed at advancing post-operative patient care to better support recovery and pain management. A select list of his publications are available below.
Dr. Cohen is currently appointed at Grafton Base Hospital, Baringa Private Hospital, St. George Public, the Sutherland Hospital as well as St. George Private and Kareena Private Hospital.

In addition to his arthroplasty practice, Dr Sadeghilar manages a wide range of foot and ankle conditions, including arthritis, sports injuries, tendon disorders, deformities, fractures, and reconstructive procedures.
