• EHS: Professor Pascal-André Vendittoli, who are you, and how can you introduce yourself as an Orthopedic Surgeon?
P-A V: I am a French Canadian orthopaedic surgeon. I work as a professor of surgery and clinical researcher at Maisonneuve-Rosemont Hospital / University of Montreal. My principal research activities are the evaluation of new surgical techniques, new technologies and new orthopaedic implants, mainly in the framework of prospective and randomised trials. Over the years, my goal has remained unchanged: offering orthopaedic patients a forgotten hip and knee joint.
I work with 10 other orthopaedic surgeons at Maisonneuve-Rosemont Hospital. We mainly do elective surgeries. As a supra-regional centre of expertise, we take care of secondary and tertiary cases in the fields of arthroplasty, oncology and sports medicine.
My practice is equally divided between hip and knee arthroplasty. Our lower limb arthroplasty unit handles the treatment of young patients with secondary arthritis, complex revisions and joint infections. Over the last 17 years, our group developed expertise using different types of large diameter head hip arthroplasty (resurfacing, metal-on-metal, dual mobility or ceramic-on-ceramic). Since 2011, we have performed more than 3000 large diameter head ceramic on ceramic THAs.1 Dr Lavigne and I designed and use the Profemur Preserve short uncemented femoral stem.
Our hospital is affiliated to the University of Montreal. It is the main teaching centre for students and doctors in training. As a Professor of Surgery at the University of Montreal, I supervised multiple Doctors in subspecialty training in arthroplasty (fellowship), Master students (MSc), Doctoral students (PhD) and postdoctoral students. I am the Program Director of the postdoctoral program in hip and knee reconstruction at the University of Montreal.
• EHS: Do you also get involved in scientific matters and clinical research in Orthopedics?
P-A V: I was elected as a Research Director of the Orthopedics Division of the University of Montreal. My research work was presented more than 300 times at peer-reviewed congresses, and I have been invited more than 200 times as a guest speaker. I published 117 scientific articles on hip and knee arthroplasty in peer-reviewed journals. My research program and research work were recognized by many organisms. In 2003, I received the Alexandra-Kirkley Award for the Best research by a young investigator by the Canadian Orthopedics Association.
In recognition of my research activities, since 2007, I have awarded the title of Clinical Researcher from the “Fonds de la Recherche en santé du Québec” (FRQS). In 2009, Dr Lavigne and I won the “John Charnley award” from the American Hip Society.2 In 2010, I received the Founders’ medal for best basic science research work by the Canadian Orthopedic Association. In 2016, I received the “Edward Samson award”, the most prestigious recognition from the Canadian Orthopedic Association.
In my quest to offer a “forgotten hip”, we improved patients results to a level where we did not find a significant difference in the gait lab between patients with an LDH THA (Large Diameter Heads) and subjects without hip replacement.2 Subjectively, our patients with LDH THA reported a mean forgotten joint score of 88.5 (best-published number to our knowledge) and 74-76% reported their hip as “natural or without limitation whatsoever2,3. My next professional goal is to improve early postoperative recovery and minimize the impact of surgery. Over the last 4 years, I worked on the development of an Enhanced Recovery After Surgery (ERAS) protocol favouring ambulatory surgery. We were able to improve the patients’ outcome to an unexpected level, reduced the adverse event rate by 50% and speed up their recovery dramatically.4
• EHS: What about your involvement in the European Hip Society, and the next International Congress in 2020 taking place in Lille, France?
P-A V: It is really a privilege and an honour to be invited to Lille by the EHS. As surgeon and scientists, I acknowledge the rigour and long-term traditions of European hip surgeon pioneers. As a surgeon, I adopted European implants and their design philosophy.
I have great friends and respected colleagues in Lille, Prof Henry Migaud and Prof Julien Girard. I am looking forward to spending some time with both of them to socialize and to discuss scientific matters.
I was asked to perform scientific lectures on my quest for the forgotten hip score which I will do with passion. I will also unveil the long term (>15 years) results of our RCT (Randomized Controlled Trial) comparing 28mm THA with hip resurfacing.2 I am looking forward to hearing the great presentations from the EHS members and I will do my best to contribute to the success of 2020 Lille meeting.
