Mr. Nikolaos Davarinos

Consultant Trauma and Orthopaedic Surgeon







Orthopaedic Surgery


Mr Nikolaos Davarinos is a Consultant Orthopaedic Surgeon fellowship trained in hip and knee replacements. Mr Davarinos holds a Specialist Registration in Trauma and Orthopaedics in Ireland, UK and Greece.

Mr Davarinos uses the latest techniques for his patients including computer assisted knee navigation and an Anterior Minimally Invasive Surgery (AMIS) for hip replacements, also known as the ‘bikini’ hip replacement. The AMIS technique allows the Surgeon to perform a hip replacement or arthroplasty through a small skin incision, avoiding injury to the muscles, tendons and nerves. The AMIS technique allows the patient to recover more quickly than some other techniques because no muscles are cut.  Patients who undergo a bikini hip replacement can potentially benefit from decreased pain after their operation, a shorter hospital stay and a faster return to daily activities.

Mr Davarinos graduated from Trinity College Dublin School of Medicine in 2004. He completed his intern year and basic surgical training in Dublin, and became a member of the Royal College of Surgeons in 2008. Mr Davarinos continued his orthopaedic training in the UK and Greece in 2015 before being awarded a specialty degree in Trauma and Orthopaedic Surgery and completed further subspecialty training in hip and knee replacement.

Mr Davarinos was awarded his first Fellowship from the European Federation of National Associations of Orthopaedics and Traumatology (EFORT). On completion of training in Geneva and Athens, Mr Davarinos focused on the AMIS technique for total hip replacement.  Mr Davarinos completed a fellowship in knee and hip arthroplasty in Canada and graduated from McGill University as an Orthopaedic Fellow in June 2018.

Areas of Specialist Interest: Apart from general trauma and orthopaedic surgeries, Anterior Minimally Invasive Surgery (AMIS) for total hip replacements and computer assisted knee navigation.
