About
Dr Yas Edirisinghe
Orthopaedic Surgeon — Hip & Knee | Adelaide
When your hip or your knee is the thing standing between you and the life you want to live, the surgeon you choose matters. You want someone who will listen carefully, explain everything in words you can understand, and bring every modern technique to bear on your particular problem.
That is the practice Dr Yas Edirisinghe has built.
A surgeon for problems that are not straightforward
Dr Yas's practice is focused on two joints — the hip and the knee — and on every kind of patient those two joints can present. Young athletes with torn ligaments. Active adults whose cartilage is failing. Older patients whose arthritis has made every step a negotiation.
He is particularly sought out when the problem is not straightforward. When a knee has been operated on before and needs revision. When previous injury or unusual anatomy makes a standard joint replacement insufficient. When another surgeon has said that the situation is too complex, or when a patient simply wants a careful second opinion before committing to surgery.
These are the cases that draw on everything Dr Yas has trained for.
Clinical focus
- Robotic-assisted total knee replacement
- Direct anterior total hip replacement
- Complex and revision joint replacement of the hip and knee
- Sports knee injuries — ACL reconstruction, patella instability, meniscal and cartilage injuries
- Knee arthroscopy and joint-preserving surgery
Technology, used where it genuinely helps
Joint replacement has changed profoundly over the last decade. Robotic-arm-assisted planning, patient-specific implant positioning, and muscle-sparing surgical approaches are now part of everyday practice — but only for surgeons who have trained in them and who know when to use them.
Dr Yas has built his practice around these technologies because, in the right hands, they allow a level of surgical precision that was simply not available before. For many patients, that translates to a knee that feels more like their own, a quicker return to walking after hip surgery, and a realistic surgical option in cases that once had none.
Technology, however, is only ever a tool. What matters is the judgement to know when to reach for it, when to set it aside, and how to adapt during surgery when the anatomy does something unexpected. That judgement comes from training, experience, and a deep interest in the craft of operating.
Training and qualifications
Dr Yas completed his medical degree at the University of Auckland before moving to Australia in 2008. He was then selected into the Australian Orthopaedic Association SET training programme, working through major public hospitals in Sydney and Newcastle, New South Wales, where he cared for the full range of orthopaedic conditions — from trauma and fracture through to elective joint replacement.
He then undertook subspecialty fellowship training in knee arthroscopy, reconstruction and arthroplasty at Westmead Hospital and the Prince of Wales Hospital in Sydney — two of Australia's leading centres for knee surgery.
He was admitted as a Fellow of the Royal Australasian College of Surgeons (FRACS) and a Fellow of the Australian Orthopaedic Association (FAOrthA) in 2022.

Entrusted with teaching Adelaide's next generation of orthopaedic surgeons
Dr Yas is the Director of Training for the Australian Orthopaedic Association at the Northern Adelaide Local Health Network — the most senior teaching role within Adelaide's northern orthopaedic training programme.
In this role, he is responsible for the education, assessment and certification of the orthopaedic surgeons who will be looking after South Australians for the next thirty years. The appointment is given by the profession to surgeons whose technical standards, judgement and integrity are trusted to set the benchmark for those in training.
For you as a patient, it is a simple reassurance: the surgeon caring for you is the surgeon other surgeons are taught to be like.
How Dr Yas works with his patients
Dr Yas believes that a good outcome begins with a good conversation. He will take the time to understand what matters most to you — whether that is walking your grandchildren to school, returning to the golf course, or simply getting through a day at work without pain — and he will build a plan around your goal rather than around the diagnosis alone.
Not every hip or knee problem needs surgery, and he will say so when non-operative care is the better path. When surgery is the right answer, he will explain exactly what is involved, what recovery looks like week by week, and what a realistic result will feel like. You will leave the consultation knowing what is being recommended, why, and what to expect.
