Dr. Christoph Kittl, MD
Head of Knee Surgery and Sports Traumatology
Department of Trauma-, Hand-, and Reconstructive Surgery (Head of Department: Prof. Raschke)
University Hospital Muenster
Christoph Kittl is a specialist knee surgeon at the department of Trauma, Hand and Reconstructive Surgery at the university hospital in Muenster, where he also completed his residency training under Prof. Michael Raschke.
In 2019 he finished his postgraduate Master of surgery degree on the anatomy, biomechanics, and reconstructions of the anterolateral structures of the knee at the department of mechanical engineering with Prof. Andrew Amis at Imperial College London. This led to his special research interest using the six-degree of freedom robotic setup.
After residency training in Austria, he completed his fellowship training in Berlin with Prof. Andreas Weiler, at the sporthopaedicum Berlin, which shaped his special interests in anatomy and biomechanics of the peripheral structures of the knee and their reconstructions.
He has published several research and book chapters on the anterolateral and anteromedial structures of the knee and his work has recently been awarded the ESSKA Ligament and Biomechanics Award, the ISAKOS Young Investigator Award, and the AGA Medi Award. Christoph Kittl is an active member of the editorial board of the AJSM, VJSM, and KSSTA and serves as a member of the scientific committee of the 2021 ESSKA congress.
