A/Professor Ernstbrunner is a consultant orthopaedic surgeon specialising in shoulder, hip and knee conditions, with advanced experience in treating osteoarthritis and sports injuries. He has a special interest in muscle-sparing and robotic-assisted joint replacements of the shoulder, hip and knee, and in complex key-hole surgery for tendon and ligament injuries.

Lukas completed his medical degree with distinction at the Paracelsus Medical University in Austria. He obtained his doctoral degree at the University of Zurich in Switzerland followed by a PhD focussing on biomechanics through a collaborative program between the Paracelsus Medical University, the Federal Institute of Technology in Zurich (ETH Zurich), and the Mayo Clinic in Rochester, Minnesota, USA.
