After studying Medicine in Münster and Zurich, Professor Tibesku served his time as an Orthopaedic Department Assistant at the Schulthess Clinic (Schulthess Klinik) in Zurich.
He began his knee surgery training as an Assistant at the ATOS Clinic Heidelberg (ATOS Klinik Heidelberg) before returning to the University of Münster (Westfälische Wilhelms-Universität Münster) as a Research Assistant. In Münster, he earned his PhD in the clinical and functional outcomes following endoprosthesis of the entire knee and continued his extensive research on the emergence of osteoarthritis and knee prostheses.
From 2005 to 2007, Professor Tibesku worked as a Senior Physician at the University of Marburg (Philipps-Universität Marburg) where he completed his higher education teaching qualification in 2006 on the movement patterns following knee prosthetics. Professor Tibesku has written more than 50 scientific papers and has given over 150 national and international scientific lectures.
Since becoming a partner at sporthopaedicum in Straubing (July of 2007 until June of 2017), he has focused his clinical activities exclusively on the treatment of knee joint osteoarthritis and is also an inpatient physician at Klinik St. Wolfgang in Bad Griesbach.
In 2010, he was awarded the chair and again made the list of doctors in the 2012 issue of Focus magazine. He is considered to be one of Germany's top doctors in orthopaedics.
Professor Tibesku utilises a technology for an artificial knee joint which is literally customised to the particular patient.
In July 2017 he started his own knee practice in Straubing.
