Prof. Dr. Werner Zimmerli

Prof Dr Werner Zimmerli

Werner Zimmerli studied medicine in Basel University, Switzerland, and obtained the PhD in 1974. After continuous education in inner medicine and rheumatology, he worked in a research project at the Department of Infectious Diseases in Geneva. The project aimed to explain high susceptibility to infection of implants lead by the pathogen mechanisms. Afterwards he worked as a chief and consulting physician in Infectious Diseases department in University Hospital Basel. This was followed by examination of function of granulocytes (tutored by John Gallin) during his research stay at the National Institutes of Health in Bethesda/USA. In 1989 he completed his habilitation in internal medicine and became a professor at the University of Basel in 1992. From 1991 till 1999 he led the newly established department of Infectious Diseases at the University Hospital Basel. In 1999 he began to work as a professor and a chief physician in inner medicine at Medical University Clinic Liestal.

Since 1979 his research focus was pathophysiology and treatment of implant infections. A major breakthrough in the treatment of such infections was the proof of the effectiveness of rifampicin against biofilm infections. Together with Peter Ochsner, an orthopedic surgeon, who worked in the same hospital in the field of orthopedic infections, and infectious diseases specialist Andrej Trampuz, he developed a treatment algorithm for patients with periprosthetic infections, which was published in N Engl J Med. Werner Zimmerli was a member of Infectious Diseases Society of America (IDSA), which published guidelines for diagnosis and treatment of prosthetic infections. The guidelines are based on published therapy algorithm and apply today as an international standard.

Since his retirement as chief medical doctor, Werner Zimmerli continues to work as a consultant professor in orthopedic infections at the Medical University Clinic Liestal.

Assist. Prof. Dr. Rihard Trebše, PhD


Rihard Trebše MD PhD, obtained his medical education at Medical University in Ljubljana, Slovenia in 1993. He defended his Ph.D. thesis at Medical University in Ljubljana under the mentorship of Prof V. Smrkolj. In 2014 has been elected as Assistant Professor for Orthopaedics at Medical University in Ljubljana. Since 2012 he works as a Head of Service for Bone Infections at Valdoltra Orthopaedic Hospital, Slovenia.

Rihard Trebše is also a deputy director of Valdoltra Orthopaedic Hospital. Between 2012 and 2015 he was the president of Slovenian Orthopedic Society, since 2009 he is a national delegate from Slovenia in European Hip Society, and since 2014 he is a national delegate from Slovenia in EFORT. His surgical expertise covers: bone infection surgeries, revision and primary hip and knee arthroplasty, osteotomies around the hip and open elbow surgeries.

Assist. Prof. Rihard Trebše, MD, PhD is a renowned scientist with various research interests. His most important research field has been the treatment of prosthetic joint infections but he was also involved in hip tribology and artificial joint survivorship studies. He is involved in design of new revision implants for acetabular reconstruction. Another focus of his work is the development and evaluation of computer aided surgical techniques for joint replacement and bone osteotomies of hip and knee joint. Since late nineties his main contribution has been in implementation of CAD – CAM technologies in orthopaedic surgeries particularly in precision osteotomy cuts and socket navigation in hip replacement. He has also been investigating the importance of synovial cytology, the role of synovial interleukin, and the significance of molecular methods in diagnosing PJI.

Prof. Dr. Olivier Borens


Olivier Borens, MD, is Head of the Department of Septic Surgery and Head of the Orthopaedic-Trauma Unit of the Department for the Musculoskeletal System of the University Hospital in Lausanne (Switzerland). He has received his medical education at the University of Bâle and specialized in orthopaedics and traumatology at the hospitals of Liestal and Lausanne. After a one-year fellowship at the Hospital for Special Surgery in New York his work concentrated on the traumatology of the acetabulum and the pelvis and on infections of the musculoskeletal system, especially following joint replacement

He has made his department a reference center for orthopaedic infections of the European Society for Clinical Microbiology and Infectious Diseases (ESCMID), welcoming visitors from Europe, North and South America as well as Australia. Olivier Borens is intensely involved in scientific activities and regularly invited to present at national and international conferences. His research focuses, among others, on the prevention, diagnosis and treatment of periprosthetic infections, biofilm, local antibiotics and minimally invasive techniques in traumatology.

He is member of the European Trauma Society (ETS) and of the Swiss AO Trauma Committee as well as Board member of the European Bone and Joint Infection Society. He takes active part in the education of medical students and the training of under- and post-graduate physicians.

Prim. Priv. Doz. Dr. Bernd Preininger


Bernd Preininger is an Austrian orthopedic surgeon who received his medical diploma at the University of Vienna. He started his professional education at the Vienna Military Hospital and in Villach where he was approved as general physician. He then further specialized on muscular skeletal surgery in Villach at the Dept. of Trauma Surgery. In 2008 he went to the Center of Musculoskeletal Surgery to Berlin where he completed his residency (Prof. Haas, Prof. Perka). As a Consultant and specialist for hip and knee prosthesis, especially for revision surgery Dr. Preininger could gain a lot of experience with complex cases. After two years in a private clinic in Bavaria where Preininger was specialized on Knee arthroplasty Dr. Preininger was called to Villach again where he now is the Head of the Orthopedic Department.
During the time in Berlin Preininger closely worked together with the team of Andrej Trampuz and thereby could develop quite some expertise in treating complex infectious cases with the specialized team there. His surgical expertise now covers all of the primary and revision arthroplasty, complex osteotomies of the leg and the foot, as well as arthroscopic interventions of the knee and the foot.
Preininger has been intensively involved in the science of bone healing as well as the optimization of knee and hip arthroplasty in primary and revision situations. Preininger is a part of the PJI workshop team for already several years and enjoys in taking over responsibility for the professional education of colleagues.
