Who are we?

Dr Patrick Vienne

Born in Fribourg, Dr. Patrick Vienne graduated from the St-Michel College in Fribourg in 1984. After his final exam in medicine at the University of Bern in 1990, he worked for 2 years in a sports medicine center in Vevey where he also had the opportunity to follow the troupe of professional dancers of Ballet Béjart in Lausanne. He then began his training in orthopedic surgery at the Riaz hospital, then at the cantonal hospital in Fribourg before joining the Balgrist orthopedic university clinic in Zurich in 1995 under the direction of Professor Christian Gerber. He obtained his medical doctor's degree by completing a thesis on the "treatment of complex proximal humerus fractures" and obtained his title of specialist in orthopedic surgery and traumatology of the musculoskeletal system in 1998. After a fellowship of 6 months by Prof. Ted Hansen at the Harborview Medical Center in Seattle (USA), he took charge of the foot and ankle team at the Balgrist Orthopedic University Clinic from 1999 to 2007. He was then certified doctor at the clinic Hirslanden St. Anna in Lucerne until April 2015 and later joined the clinic Hirslanden Bois-Cerf in Lausanne in May 2015.

Dr. Patrick Vienne has went on to publish numerous articles in international journals specializing in the field of the foot and ankle anatomy and he is at the origin of the development of an innovative surgical technique aimed at correcting the deformation of the hallux valgus. He has also worked as a European expert in the introduction of a new total ankle prosthesis in the early 2000s. With the benefit of more than 25 years of experience in his specialization, he is able to propose a solution that is conservative, or surgical (primary or revision) to all pathologies affecting the foot and ankle.

On the sporting side, Dr. Vienne is a fervent fan of running, finishing twice third place at the famous Sierre-Zinal mountain race in 1994 and 1995. An activity that has certainly motivated him to be interested in problems concerning the anatomy of the foot and ankle.

Dr Etienne Ruffieux

Dr Etienne Ruffieux is originally from Fribourg and completed his medical studies at the Universities of Neuchâtel and Geneva, where he obtained his medical degree in 2014. He began his residency in Orthopaedic Surgery and Traumatology of the Musculoskeletal System in 2015 at the Department of Orthopaedics and Traumatology of the Geneva University Hospitals (HUG), where he held the position of Chief resident in the Foot & Ankle Unit from 2022 to 2025 under the supervision of Dr Diogo Vieira Cardoso. Dr Ruffieux obtained his FMH specialist title in Orthopaedic Surgery and Traumatology of the Musculoskeletal System in 2025.

In 2025, he completed a two-months fellowship at the Foot and Ankle Institut in Brussels with Drs K. Buedts and B. Devos Bevernage, followed by a two-months fellowship with Dr Rabat in Barcelona. These experiences enabled him to exchange knowledge, observe, and practice advanced surgical techniques.

Dr Ruffieux's arrival at La Clinique du Pied will further enhance the management of patients suffering from foot and ankle disorders by reducing waiting times for consultations and surgical procedures. He will work in close collaboration with Dr Vienne, under his supervision, and will adopt La Clinique du Pied's treatment philosophy while progressively acquiring the surgical expertise required for the management of complex pathologies. 

On a more personal note, Dr Ruffieux is passionate about aviation (holding several active licences). He practiced fencing for 17 years and played American football for 5 years.

Dr Christopher Tzioupis

Of Swiss and Hellenic nationality, Dr Christoforos Tzioupis began his orthopaedic training at the University of Athens. Between 2007 and 2011, he completed several international fellowships in the United States, the United Kingdom, and Germany. In the United States, he worked at the University of Pittsburgh Medical Center as an Associate Scholar – Fellow, conducting research in bone and ligament regenerative medicine in collaboration with the School of Dental Medicine and the McGowan Institute of Regenerative Medicine. He then pursued a trauma fellowship at Leeds Teaching Hospitals (United Kingdom) before joining the Charité in Berlin, where he practised until 2011.

In 2013, he defended a PhD in medicine focused on regenerative medicine and bone healing. His FMH specialist title in orthopaedics and trauma of the musculoskeletal system was recognised in Switzerland in 2014.

He then worked for several years at Medicol Lausanne as an assistant doctor, where he actively contributed to various clinical research projects, notably in collaboration with EPFL and different university centres.

In March 2022, Dr Tzioupis joined the Clinique du Pied – Hirslanden Clinique Bois-Cerf, to undertake a fellowship in foot and ankle surgery under the direction of Dr Patrick Vienne. He currently holds the position of deputy head of clinic.

Dr Tzioupis provides consultations for patients referred to the Clinique du Pied, both for new assessments and follow-ups, under the supervision of Dr Vienne. He also assists in surgeries as needed and offers personalised conservative treatments, in accordance with the Clinic's protocols.

Author and co-author of numerous scientific publications and chapters in specialised books, he remains actively engaged in continuing medical education and applied research in orthopaedics and trauma.

Outside his medical practice, he is a qualified violinist and has performed with, among others, the National Orchestra of Greece. Passionate about music and motorsport, he combines scientific rigour and artistic sensitivity in his professional approach.

She then decided to complete her training and get her degree as a nurse at the Health Highschool of Fribourg (HEdS) in 2011.
