Rafael Arriaza, MD, PhD
Universidade da Coruña
A Coruña, Spain

Born Dec. 2, 1960, in Madrid (Spain). I started medical education at Madrid’s biggest university and then, there were two circumstances that clearly decided my future. The first one was the fact that I was gifted or lucky enough to enter the Spanish National Karate Team. Undoubtedly, getting there was not without its share of discipline, a lot of sweat and hard work, endless technique repetitions, life-long friendship, travels and, obviously, some injuries. The second one was that the fact of having experienced myself what an injury means to an athlete led me to choose, in 1984, an Orthopaedic residency program, where I was again lucky enough to meet some incredibly good teachers, including one of the founding partners of the Spanish Arthroscopy Association, created just in 1982, who acted as my mentors and helped me to develop solid arthroscopic skills.

In 1987 I married my wife, Belen, who has been my strong supporter since then, and in 1989 our first son was born, soon followed by another two. By then, I had obtained the University Degree of Sports Traumatology from the University of Nice (France) and was acting as team doctor for the Spanish karate squad. We decided to move to a smaller city by the seaside (La Coruña, in Galicia), and in 1990, I was designated as Chairman of the Medical Commission of the World Karate Federation. Two years later, I started teaching on “Injury Prevention and Exercise Rehabilitation” at the University of La Coruña, and became Head of Sports Traumatology for the Deportivo de La Coruña soccer team, at a time when the team reached top positions in the Spanish and European leagues, and I had the pleasure and the responsibility of treating players who were at the same time playing for their national teams, which made me develop links with top colleagues from all over the world. One of our sons has qualified as orthopaedic surgeon in Madrid, another one qualified as an osteopath in Wales and is actually living in New Zealand, and the third one is working in marketing and branding in La Coruña. In 2012, we opened a new facility, sport-focused, the Instituto Médico Arriaza y Asociados, which has been honoured as Teaching Center for the Spanish Arthoscopy (AEA) and the Spanish Sports Traumatology (SETRADE) societies, as well as ESSKA and ISAKOS. At the same time, I got the assignment to coordinate the Chair of Sports Traumatology at the University of La Coruña, and we receive residents from Spain and Portugal for short-time stays and fellows mainly from Spanish-speaking countries.

Andy Williams MB, BS
Founder, Fortius Clinic
London, UK

Knee surgeon at, and founder of Fortius Clinic, London, UK; Reader at Imperial College London; and Honorary Senior Research Fellow, Nuffield Department of Orthopaedics, Rheumatology, and Musculoskeletal Sciences, University of Oxford. He qualified from King’s College Hospital, London in 1987. Orthopaedic training at The Royal National Orthopaedic Hospital, Stanmore, and a year’s Fellowship in Brisbane, Australia with Peters Myers and McMeniman. This is where his experience with sports-related surgery began. On return to the UK in 1997 he became Senior Lecturer / Honorary Consultant at The Royal National Orthopaedic Hospital, Stanmore.

Elective practice is exclusively soft tissue knee surgery, and he undertakes around 100 ACL reconstructions per year, of which more than half are on professional athletes, and a multi-ligament reconstruction every 1-2 weeks. This latter work represents one of the World’s largest experiences. He has been the primary knee surgeon for many of the UK’s professional sports teams, including 75% English Premier League soccer, and 80% English Premiership rugby teams for many years. 70% of his patients are professional sportsmen and women, and over 50% of all his operative cases involve this group. He has published over 120 peer-reviewed articles. His study of knee motion employing weight-bearing, ‘dynamic’ MRI fundamentally changed thinking in the field.  For this he was awarded The Hunterian Professorship by The Royal College of Surgeons of England for 2005-2006. Current research interests are in the fields of inflammatory response to knee injury, and biomechanics at Imperial College, London, where an anatomical study of the lateral soft tissue restraints aiding the ACL was awarded the Trillat Prize at ISAKOS 2015. Current work there focuses on the medial ligament complex. He was a lead editor of the 39th Edition of Gray’s Anatomy published in December 2004. He was on the executive of The British Association for Surgery of The Knee. He sits on the Editorial. Board of The American Journal of Sports Medicine, and previously the Editorial Board of The Bone and Joint Journal and serves on the Knee: Sports and Preservation committee for ISAKOS, as well as The ESSKA Sports Committee.  In 2002 he was awarded the ABC Travelling Fellowship. He was named in the UK’s Top 100 Doctors by The Times newspaper in 2011. He is the first UK member of The Herodicus Society, a U.S. sports surgery organisation.

Paul W. Ackermann, MD
Karolinska Institutet

Karolinska University Hospital
Stockholm, Sweden

Dr. Paul W. Ackermann is a Senior Lecturer at Karolinska Institutet, and orthopaedic surgeon at the Department of Orthopaedics and Trauma, Karolinska University Hospital, both in Stockholm, Sweden. His passion for sports and particularly basketball and soccer led him to get involved with sports injuries, and this was the reason to enter a residency in orthopaedics. His mentor, Professor Per AFH Renström, a well-respected figure in orthopaedic sports medicine, introduced him to the world of sports medicine.

The mission of Dr. Ackermann’s research is to understand and exploit neurovascular pathways in the musculoskeletal system for restoring joint function, alleviating pain, and minimizing complications.

Dr. Ackermann’s research has demonstrated that patients with Achilles tendon ruptures exhibit a high risk, 50%, of suffering deep venous thrombosis. Even a silent deep venous thrombosis has by Dr. Ackermann’s research group been demonstrated to affect the patients´ outcome at one year after the rupture. 

One means to facilitate the development of improved treatment of tendon injuries pursued by Dr. Ackermann’s research group is to develop biomarkers for early healing, which can predict long-term outcome. Currently Dr. Ackermann holds a grant from the Swedish Research Council to examine the effects of Intermittent Pneumatic Compression (IPC) on tissue repair and prevention of deep venous thrombosis during lower limb immobilization.

After medical school in Louvain, Belgium, Dr. Van de Velde joined the Bioengineering Laboratory at the Massachusetts General Hospital, Boston, MA, where he studied the biomechanical pathogenesis of osteoarthritis in patients with cruciate ligament deficiency. This NIH-funded investigation was commemorated with a PhD in Medical Sciences at the University of Leiden, the Netherlands. While in Boston, Dr. Van de Velde obtained a master’s degree from the Harvard School of Public Health, received the Ruth L. Kirschstein Award from the NIH, and won the O’Donoghue Sports Injury Award together with Thomas J. Gill, IV, MD. He has published more than 50 peer-reviewed articles and has presented his research at numerous annual medical conferences and symposiums both nationally and internationally.

Dr. Van de Velde did his orthopaedic surgical training at Leiden University Medical Center, the Netherlands. He then visited the Royal Children’s Hospital Melbourne, Australia, followed by a one-year clinical fellowship in pediatric orthopaedic surgery at the Hospital for Sick Children in Toronto, Canada. After the general pediatric orthopaedic training, Dr. Van de Velde completed one year of training in the diagnosis and specialized treatment of hip and knee pathology in children and young adults in Perth, Australia. Surgical treatments included periacetabular and femoral osteotomy, surgical dislocation and femoral capital realignment, hip arthroscopy and hip joint replacement, and knee ligament reconstruction. In addition to the joint preservation fellowship, Dr. Van de Velde participated in two medical missions to the Comoros Islands in Africa. During these missions he performed complex limb alignment and corrective surgeries while training local providers in the developing world in the Ponseti method for clubfoot deformity. Finally, Dr. Van de Velde received extensive training in the treatment of complex pediatric foot and ankle deformities and malformations during his fellowship training at Seattle Children’s Hospital in Seattle, Washington.

He lives with his wife and three children on Park Slope in Brooklyn, NY.
