Five years Amsterdam collaboration on health and safety in sports

Five years Amsterdam collaboration on health and safety in sports

In 2016 is Amsterdam Collaboration on Health and Safety in Sports (ACHSS) geaccrediteerd als een van de elf wereldwijde IOC-research centra. Nu, vijf jaar later, blikt het ACHSS team terug en kijkt het vooruit. Wat heeft de samenwerking in Amsterdam opgeleverd?


Ankle Cartilage Team: Jari Dahmen

Amsterdam Ankle Cartilage Team: Jari Dahmen Appointed Editor KSSTA Journal and Editorial Board Member CARTILAGE Journal

Care for athletes goes hand in hand with high-quality research. At ACES, patient care is guided by ever increasing insights in diagnosis and treatment from the latest scientific research. The department of Orthopaedic Surgery of Amsterdam UMC has been officially accredited as an Expert Centre for the treatment of ankle cartilage injuries in 2018. The foundation of its clinical research is rooted in a wide network of an enthusiastic research and clinical team. Jari Dahmen currently helps to coordinate this team of researchers in the field of ankle cartilage, which led to the publication of numerous high-quality scientific reports. The continuous efforts for the best evidence are in the service of patients and their families being impacted by cartilage damage in the ankle.

The contributions of Jari to the field of ankle cartilage repair has not gone unnoticed. At the end of 2020 Jari was appointed as (web-)editor at the KSSTA journal from the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) and as Editorial Board member for the CARTILAGE Journal – which is the official journal of the International Cartilage Regeneration & Joint Preservation Society (ICRS). He is furthermore involved as a Board Member in the International Society for Cartilage Repair in the Ankle (ISCRA).

Jari emphasizes that these accomplishments are predominantly thanks to the concerted group efforts of the enthusiastic young (student) researchers, research fellows, and doctors that are all part of the Amsterdam Ankle Cartilage Team and happily works together within this team.

Within 30-40 years, Osteoarthritis will be history

Gino Kerkhoffs by Marieke de Lorijn

Gino Kerkhoffs, Professor and Head of Department of Orthopedics, Amsterdam UMC
Together with a team of sports physicians, radiologists, movement scientists and physiotherapists, Professor Kerkhoffs has set up a center of expertise for the continuous improvement of care for injured (top) athletes. The Academic Center of Evidence based Sports medicine (ACES) stands for a combination of integrated diagnostics, tailor-made treatment and high quality rehabilitation protocols with a longitudinal monitoring of all results to optimize the outcome. The research focusses on primary (surgical) preventive interventions for the treatment of joint disorders of the lower extremity (i.e. the legs), with a focus on ankle cartilage injuries and sports injuries.

Does movement matter?
‘Keeping people in motion brings health gains in all areas. The importance of sports and exercise within society is growing, as sports is becoming an increasingly important aspect of life. The understanding that exercise contributes to the prevention and treatment of numerous diseases is becoming more and more evident. At our department we have a major role in keeping the athletes and the people of the Netherlands healthy, starting from primary prevention of injuries, to mental health, and further on to the prevention of osteoarthritis. Sports can also cause damage to the musculoskeletal system, such as joint wear and tear. If you can eliminate this and are able to position the muscles optimally and prevent cartilage damage, you can create optimal conditions to benefit movement. With better cushioning of a joint, you can prevent cartilage damage or osteoarthritis, even before it really starts. In this way, movement is healthy, without any side effects. Preventing the overload and inflammation of the joint, that’s what it’s all about.’

How can you prevent osteoarthritis?
‘Cartilage research is what we are good at, as is seen in a nice cross-pollination collaboration between Theo Smit (professor of Translational Regenerative Medicine, Amsterdam UMC, location AMC) and a company that deals with body materials, including cartilage substitutes. We hope that cartilage damage can be prevented in the future. This prevention was primarily thought off for top athletes, as well as for people with excess weight, or with such low muscle function that they put too much strain on the joints at an early stage. However, the preventive intervention seems interesting for the whole population in motion. In people who already have some osteoarthritis, we aim to slow down the process so that eventually hip or knee replacements become superfluous. Our aim is that osteoarthritis will be eradicated in 30 to 40 years time. It is therefore a primary, preventative task of great societal impact. After all, osteoarthritis is considered one of the most common diseases of our time. The cartilage of the ankle expands to cartilage of all the other joints. We see a lot of patients with ankle disorders, and the model can easily be transposed. The same goes for the muscles, there are a lot of muscle injuries that limit movement abilities, albeit often to a lesser extent than with disorders of the cartilage’.

How important is the mental aspect in the healing process?
‘I think it is important to consider the whole person in the healing process, certainly also the mental aspects. While longitudinal evidence about any causal relationship is lacking, the suggested relationship between sports career-related concussion and mental health symptoms in former elite athletes warrants the development of support measures for elite athletes transitioning out of sports. Especially for those with a history of concussion. What effect did it have on Dutch international Van Basten when he had to stop playing soccer? If you can’t do what you like best anymore, in all the roles you have, you are limited. He is the former best player of the world. The Drake Football Study The Drake Football Study, successfully initiated by former professional player Vincent Gouttebarge, will measure a range of variables across cardiovascular, musculoskeletal, cognitive and mental health, but will also track players over at least 10 years, thus hopefully filling the gaps in knowledge around the onset and progression of several health conditions associated with a career in football’.

Does research collaboration make a difference?
‘We joined forces even before the official merger between AMC and VUmc back in 2015. The collaboration gives synergy: 1 + 1 = 3. The bundling of research on prevention and treatment of sports injuries from the partners at VUmc and AMC is a highlight in recent times in the Netherlands. This spontaneous collaboration led to an official accreditation as one of ten International Olympic Committee Research Centers for the protection of the Athlete’s health, chaired by professor Evert Verhagen from VUmc and myself. Our team also hosts a number of Team NL’s clinical preferred partner positions with professor of Radiology Mario Maas, cardiologist Harald Jørstad, Simon Goedegebuure and Niels Wijne from Sports medicine and myself in Orthopedics. The Sports medicine research in our center is in great hands with Hans Tol, who was recently appointed as the first professor of Sports Medicine at Amsterdam UMC and leads a talented team of sports medicine researchers. This bundling of expertise provides many more starting points, in addition to what was always there as part of AMS. We are able to work together with several disciplines to address the matter. I’m very keen on this multidisciplinary approach, because it provides the cross links that strengthen the foundation of our research and very important it is more valuable, powerful and above all more fun to work as a team’.


ACES Ajax

Extension of 3-year contract with AJAX

Extension of 3-year contract with AJAX

ACES Ajax

AJAX has recently extended the contract of Sports physician Hans Tol for a period of 3 years. The contract, which runs since 2018, is thanks to the high-quality top sport medical care that is offered by the Academic Center for Evidence-Based Sports medicine (ACES) of Amsterdam UMC, location AMC.

ACES combines multidisciplinary care of elite athletes with scientific research and education. Tol: “Within ACES we have very short lines of communication between sports medicine, Gino Kerkhoffs of sport traumatology and orthopaedics, Peter Struijs of paediatric orthopaedics, Mario Maas of sport radiology and Harald Jorstadt of sports cardiology. As a result, we can offer AJAX the best possible care 24/7. Additionally, medical professionals of AJAX have direct access to our education and profit from the insights that we attain through scientific research. Meanwhile, we manage to keep our feet planted in the mud of elite football. The experiences that we gain there is beneficial to all athletes under treatment in Amsterdam UMC.”

Scientific Research
The cooperation with AJAX has enabled ACES to make growth related injuries a research priority. Tol: “Until recently, little research had been done on this topic, despite certain injuries being career-limiting at a very young age. Osgood-Schlatter is such an example; an injury of the knee that frequently occurs in growing young boys. It is described as an innocent injury that is self-limiting. However, we suspect that this injury has many long-term consequences than is currently assumed. A torn cross ligament, that always receives plenty of attention, is likely less career limitating than growth related injuries.”

Sports physicians Amsterdam UMC
The daily sports medicine care at AJAX is in the hands of a large team. Besides Hans Tol, two other sports physicians of Amsterdam UMC are part of that team: Guus Reurink and Niels Wijne. The last two mentioned physicians are employed by AJAX for this purpose. Reurink, together with Tol, is responsible for all care associated with the youth selections. Additionally, they accompany the games of the Young-AJAX. This team, with the big, young talents, play in the so-called Keuken Kampioen Divisie (First Division). Niels Wijne is head of the medical staff at AJAX and accompanies the first team.

Basketball players for calf muscle research

Orthopaedic Surgery basketball players

At the Academic Medical Center Amsterdam, the department of Orthopaedic Surgery is looking for basketball players (male and female) that would like to participate in scientific research to assess the efficacy of calf exercises on performance and the prevention of muscle injury.

As an athlete you want to improve performance and reduce the risk on injury. Former research has shown that an increase in calf muscle force can positively change the jumping height. With the application of a novel MRI technique, the researchers would like to visualize muscle characteristics to understand the mechanism of preventive exercises on muscle morphology in the calf muscles.

What does participation mean?
When the basketball player is contacted by the researchers a first MRI scan and intake is scheduled. The player is then randomized into one of the three groups: Interventiongroup A (Alfredson’s eccentric heel drop), Interventiongroup B (Concentric heel raise) or in a controlgroup (no intervention). The intervention period will take 12 weeks following an individual exercise plan. These exercises will cost no longer than 3 times 15 minutes per week. Travel expenses are reimbursed.

The exercises can be easily executed on the stairs or on a small elevation. If you are a female or male basketball players, 16 years or older, curious and excited to participate in this research? Sign up and let us know by sending an e-mail to l.s.bannink@amsterdamumc.nl or sign up via our website!
