About me



I graduated from the Albert Szent-Györgyi Medical University in 1998 with an overall grade of “summa cum laude”.

I began my medical carrier at the Department of Orthopaedics of the University of Szeged, and after a seven year span in England and Australia, I have recently returned to take up a Consultant and Senior Lecturer/Assistant Professor post. I have completed my basic orthopaedic training in 2003, with an excellent result.

Between 2004 and 2006 I spent my two years additional traumatology training at the Department of Traumatology, University of Szeged and at the Bekes County District General Hospital in Gyula, Hungary. I have completed the full orthopaedic and traumatology training in 2007.


I have spent almost seven years in the United Kingdom and Australia.

Fellowships: I was lucky enough to have the opportunity to work as a fellow, receiving subspecialty training for more than three years. I have spent 6 months alongside Mr Richard Villar who is a hip specialist at the Wellington Hospital in London, training in Hip Arthroscopy, Hip resurfacing, Primary and Revision Hip Arthroplasty. Next, I spent more than 12 months with Mr Nick Fiddian, the President of the British Knee Society at that time dealing with primary and revision total knee replacement (partial or total), knee arthroscopic techniques, including hamstring and patella tendon anterior cruciate ligament (ACL) reconstruction, patella realignment, etc. I have spent 6 months with Mr Robert Middleton who is a hip specialist at the Royal Bournemouth and Poole hospitals, and I was exposed to a large number of primary and revision total hip replacements in both the elective and the fracture setting. I have spent 18 months in Newcastle, New South Wales, Australia, working alongside Professor Zsolt Balogh at the John Hunter Hospital as a trauma fellow. I was involved in both clinical trauma care of complex injuries and basic and clinical research.

For more than 3 years I have worked at the Consultant Orthopaedic Surgeon level at the Royal Bournemouth Hospital (the place of my previous knee and hip fellowships). This large district general hospital performs 13000 orthopaedic and trauma operations each year (including 2500 lower limb joint replacements). The Consultant position is the highest specialist rank in the United Kingdom. At the Royal Bournemouth Hospital I performed 400-450 operations a year, which equated more than a 1000 primary hip and knee replacements over my time there, and 80 revision hip and knee replacements, 100 ACL reconstructions, more than 600 knee arthroscopies and numerous other general orthopaedic and trauma procedures (foot, hand, shoulder and general trauma operations).

The approximately seven years spent in England and Australia has greatly widened my general and specialist orthopaedic and trauma knowledge, and had the opportunity to learn from established experts/mentors who belong to the international elite in their field. I also had the opportunity to actively participate at well-known international courses, where I was able to learn from orthopaedic and trauma leaders.

In 2013, I was accepted into the Royal College of Surgeons – and hold the title FRCS (Fellow of the royal college of surgeons.

2013 -

I have returned to the Department of Orthopaedics, University of Szeged in September of 2013. In 2014 I was appointed assistant professor/senior lecturer. I have continued to introduce, use and fine tune all the surgical techniques acquired in the UK and Australia (minimized posterior approach to the hip, surgical planning for reconstructive surgery, arthroscopic hamstring anterior cruciate reconstruction, modern combined treatment for patellofemoral instability (MPFL reconstruction and Fulkerson osteotomy), revision techniques in hip and knee arthroplasty. I have continued to educate residents and orthopaedic trainees in these techniques. I was instrumental in organizing several conferences in these topics with the involvement of international faculty. I have been a certified instructor of AO (arbeitsgemeinschaft für osteosynthesefragen) since 2017, representing AO Recon, the joint replacement branch of AO, both in Hungary and Central Europe. I have been a member of the board of the Hungarian Orthopaedic Association since 2017. I have completed my habilitation in 2019. The title of my habilitation lecture was: Surgical planning in primary and revision arthroplasty. In July of 2020, I was appointed Associate Professor and was also entrusted with the position of interim Head of Department.
