Volker Musahl, MD, is Professor of Orthopaedic Surgery and Bioengineering at the University of Pittsburgh, Chief of Sports Medicine at the UPMC Freddie Fu Sports Medicine Center, Program Director of the Sports Medicine fellowship program, and associate head team physician for the University of Pittsburgh Football team. Prof. Musahl has received numerous honors and awards and has published over 400 peer reviewed publications.

He is Deputy Editor-in-Chief of Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA). His research interests are broad, but his main focus is on the clinical and basic science of knee and shoulder injuries in athletes. He serves as Co-Director of the Orthopaedic Robotics Laboratory, a state-of-the-art robotics laboratory which is the first of its kind in the United States. His research interests include clinical outcomes research and biomechanics of the knee and shoulder. He is currently Co-Principal Investigator for two large scale multi-center randomized control trials, on knee ligament injuries. The STABILITY II trial funded by the NIH (National Institute of Health). The project aims to determine if graft type (QT, BPTB, i.e., Quadriceps tendon or Patella tendon) with or without a lateral extra-articular tenodesis (LET) affects the rate of graft failure two years after anterior cruciate ligament reconstruction (ACL-R), patient-reported outcomes, donor site morbidity, complications and adverse outcomes, and Cost-effectiveness of ACLR and LET. He is Co-Principal Investigator of the STAR (Surgical Timing and Rehabilitation) for MLKIs). The purpose of this study is to investigate effects of timing of surgery (early vs. delayed) and timing of post-operative rehabilitation (early vs. delayed) for the treatment of military personnel and civilians that sustain a multiple ligament knee injury. This is a department of defense (DOD) study. He is also Co-Investigator for the POETT trial (Predicting the Outcome of Exercise Therapy for Treatment of Rotator Cuff Tears). This study is an NIH grant. This trial aims to develop diagnostic methods to allow surgeons to determine whether physical therapy or surgery is the most effective initial treatment of rotator cuff tears.

Anders Troelsen is a professor of Orthopaedics at the Copenhagen University Hospital in Hvidovre, Denmark. He serves as a senior consultant performing knee and hip arthroplasty. He has a particular focus on individualizing the treatment of knee osteoarthritis based on wear patterns by means of unicompartmental knee arthroplasties. In his current practice 2 of 3 patients receive a unicompartmental knee arthroplasty.

In the past years, Anders Troelsen cooperated on publishing more than 270 peer-reviewed papers in national and international journals. In the recent literature he has contributed to an increased understanding of the benefits of unicompartmental knee arthroplasty and how to optimize outcomes.

In 2025 Anders Troelsen is the president of the European Knee Society (EKS). 

Professor Dr Jan Victor obtained his medical degree in 1985 from the University of Leuven and his board certification in orthopaedic surgery on August 6^th, 1991. His clinical career is dedicated to the treatment of knee pathology, including arthroscopy, soft tissue procedures, osteotomy and joint reconstruction.

From 1991 to 1995, he was staff member at the department of orthopaedic surgery at Leuven University Hospitals. From 1995 to 2011, he was staff member of the Department of Orthopaedics Surgery at St-Lucas General Hospital, Bruges, where he became head of the department in 2010. In 2009 he obtained his PhD with the thesis ‘A Comparative Study on the Biomechanics of the Native Human Knee Joint and Total Knee Arthroplasty’. In 2011 he was appointed Professor at Ghent University and Chairman of the Department of Orthopaedic Surgery and Traumatology at the Ghent University Hospital.

He has published over 180 papers in international peer-reviewed journals, published several books and wrote multiple chapters on knee pathology and surgery in orthopaedic handbooks. He is reviewer for a significant number of peer-reviewed journals in the field of orthopaedics and biomechanics. 

He was president of the Belgian Society of Orthopaedic Surgery and Traumatology in 2002 and 2003. He is founding member of the Belgian Knee Society (BKS) of which he was President from 1999 to 2001. Since 2005 he is an active member of the American Knee Society. He was president of the European Knee Society in 2016 (EKS) and is board member since. He is honorary lifetime member of the International Society for Technology in Arthroplasty (ISTA). He is a member and scientific advisor of the European Federation of National Associations of Orthopaedics and Traumatology (EFORT) and the American Association of Orthopaedic Surgeons (AAOS). He organised multiple national and international congresses and participated as a speaker at numerous orthopaedic meetings worldwide.

He was awarded several times (best scientific exhibit AAOS 2009, John Insall Award 2009, Ranawat Award 2011, American Knee Society, honorary membership of SOFCOT). He holds several patents in the field of knee arthroplasty and co-designed several implants and surgical instruments.
